Rheinblick 741

Rheinblick 741 in Düsseldorf

Nomen est Omen

A pioneering swimming venue and meeting place for leisure, sports and politics on the banks of the Rhine.

The barrier-free building also plays host to a district administration office, including rooms for meetings and conferences for district representatives.

In cooperation with the Bädergesellschaft Düsseldorf mbH, the North Rhine-Westphalian state capital of Düsseldorf has realized a pioneering swimming venue and meeting place for leisure, sports and politics on the banks of the Rhine.

With its shape and silver-grey facade, the organic building complex is reminiscent of a pebble lying next to the Rhine. It houses an indoor pool, a physiotherapy practice, a fitness room for use by clubs and for physiotherapy as well as an event room for up to 200 people.

The new multifunctional and completely barrier-free building also plays host to a district administration office, including rooms for meetings and conferences for district representatives. Next to the complex there is a large area with 131 parking spaces as well as bicycle parking spaces. And right across from that there is a 50 by 70 metre football training pitch.

The swimming area includes a 25-m pool with diving towers, a separate 15 × 8 metre teaching and lesson pool with an adjustable floor and a playfully designed children’s splash area.

“Rheinblick 741 – Begegnung am Wasser” is the only indoor pool in Düsseldorf that offers swimmers a view of the Rhine.

Thanks to the large windows, the interior is flooded with daylight.

The swimming area includes a 25-metre pool with diving towers, a separate 15 × 8 metre teaching and lesson pool with an adjustable floor, a warm water pool and a playfully designed children’s splash area with many colourful water toys. One highlight here is the “Miniature Rhine”, which flows through the area and can be dammed up.

 

Around the lesson pool, there is a long stone bench from which all areas are visible.

Particularly eye-catching are the triangular Troldtekt ceiling panels seemingly reflecting the surface of the water.

In the children’s area, turquoise mosaic tiles combined with brown floor tiles and brightly coloured walls create a friendly atmosphere. In the swimming area, large brown floor tiles are paired with brown mosaic tiles, creating a warm contrast to the bright walls.

Particularly eye-catching and an important design element are the triangular Troldtekt ceiling panels that have been installed, seemingly reflecting the surface of the water.

Troldtekt is cement-bonded wood wool panels that ensure good acoustics in any room. The acoustic panels are manufactured using certified wood, which is a 100 per cent natural material, and cement, which is extracted from Danish mineral resources.  

This provides a healthy and strong material with unique sound absorbing properties.

The swimming pool of the future

The swimming pool of the future

Games. Sport. Recreation.

These trends cover a wide range of aspects that impact on architecture – from economics and digital features to new usage patterns.

IAKS has compiled a report on a number of trends in the swimming centres and outdoor baths of the future.

Swimming and water exercise are popular activities among all ages and at all skill levels. We also use swimming centres to relax – or to be active with our families. The varying usage scenarios place demands on form and function when developers, architects and builders have to jointly arrive at the perfect design.

In a report, the German International Association for Sports and Leisure Facilities (IAKS) NGO listed trends in future swimming centres. The 16 trends can be useful to keep in mind – right from the drawing board stage.

These trends cover a wide range of aspects that impact on architecture – from economics and digital features to new usage patterns.

Swimming is popular

Blurred boundaries between work and leisure are making individual, flexible activities such as swimming, running and cycling increasingly popular. This entails a need for better access to swimming pools and extended opening hours.

Accessibility is not only about focusing on users with physical disabilities. Changes in demographics and ethnic diversity also place special demands on swimming centres.

A lifelong healthy lifestyle

Exercise in water helps fulfil the desire to lead a healthy life at any stage of life. An increasing number of seniors are demanding good exercise pools. Since fewer parents are teaching their children to swim, there is also a need for teaching pools – ideally with an adjustable/movable floor.

Wellness is gaining ground

The combination of sport and relaxation has become more popular. It is therefore a good idea to complement the classic competition and exercise pools with wellness facilities such as spas, saunas, Turkish baths, treatment facilities and lounge zones.

Fun for children and families

Families with children are an important target group for swimming centres. It is therefore important to have facilities that support play and give children a good introduction to the water.

Designing for inclusivity

Accessibility is not only about focusing on users with physical disabilities. Changes in demographics and ethnic diversity also place special demands on swimming centres. Everything from stairs and changing rooms to signs and lighting can have an impact. It is important to involve all key stakeholders early in the design phase.

Sustainability and carbon footprint also play a major role in the construction of swimming centres.

Pools as places for socialising

Leisure activities are also a hub for socialising. It is important to encourage young people to meet at the swimming centres. And again, it is important to involve users in the design process.

Sustainable and healthy facilities

Sustainability and carbon footprint also play a major role in the construction of swimming centres. Measures that save water, recover heat, harness solar energy and minimise waste must be in focus. Ideas about a healthy lifestyle also place demands on technical conditions in relation to things like water and air quality.

Safe and secure pools

The risk of ‘anti-social behaviour’ may necessitate video surveillance above and below the water, and increased use of security personnel at swimming centres.

Competing demands on public finances

Government investments have to be prioritised. To secure funding for a swimming centre, the parties behind it have to be able to highlight the social value of the project. Partnerships with non-profit organisations or private companies may be a model for financing.

A swimming centre can be combined with a sports hall, a gym or even a library.

Improving economics

Swimming centres should ideally be operated without incurring losses. A swimming centre can be combined with a sports hall, a gym or even – as seen in England – a library. Achieve economies of scale by managing indoor and outdoor facilities in the same region in a single unit.

Private sector focuses on profitable cases

It can be difficult for municipalities to balance their budgets. Private players often invest in the most profitable business cases, such as gyms and large wellness centres. This can leave municipalities with the less attractive ones. When this happens, it is important to focus on the social rather than the economic benefits.

Digital transformation

Digital features also have an impact on the architecture of new swimming centres. The ability to track your performance in the water, water slides with virtual reality and cash-free payments are examples. In terms of the actual construction process, building information modelling (BIM) will become increasingly significant.

User expectations are growing

People are travelling more and experiencing more online. This can increase expectations of user experiences – including when visiting the swimming centre. It is therefore important that new swimming centres meet current international standards.

Good design is essential to ensuring a good user experience – so that visitors keep coming back.

Scarcity of space

Given the shortage of space in many cities, swimming centres need to serve multiple purposes. For example, an outdoor baths in summer could double as a skating rink in winter.

Fight for talent

When the economy is healthy, it can be difficult to find enough skilled staff for swimming centres and other sports facilities. Internal training can be one way to attract and retain employees. Technological solutions may in some cases be able to replace employees.

Good design

As evidenced by the trends outlined above, designing and building a new swimming centre is a complex task. But it is important to do this well. Good design is essential to ensuring a good user experience – so that visitors keep coming back.

Therme Lindau

Therme Lindau

All in

Minimalist charm and unique design, promising extensive bathing fun and maximum relaxation.

Therme Lindau offers a unique wellness and bathing landscape spread over 13,000 m² and including a spacious outdoor area with a spectacular view of both water and mountains.

Designed by 4a Architekten GmbH from Stuttgart (Germany) and nestled in the beautiful landscape between Eichwald and Lake Constance, the spa in Lindau is located on the shore of Lake Constance.

The elongated new building features expansive windows and a wood/concrete facade, inviting you to linger in its unique wellness and bathing landscape spread over 13,000 square metres and including a spacious outdoor area with a spectacular view of both water and mountains.

The elongated building was aligned with the edge of the shore. The ground floor features the various areas of experience. Above this, gently embedded in the landscape between Eichwald and Lake Constance, lies the second level.

The water attractions in a total of six different pools include a lazy river, a wild stream complete with tube water slide, a water cave for children and a giant whirlpool for up to 30 people.

The spa features a family and sport pool, including a 25-metre Olympic swimming pool and an expansive area boasting thermal baths, a wellness centre and saunas.

An elegant and inviting dining area with a pool bar overlooking the lake, a fitness area as well as a spa area that can be booked for private use complete the premium wellness offer.

The water attractions in a total of six different pools include massage loungers, bubble seats, neck jets, a lazy river, a 40-degree spring pool, a wild stream complete with tube water slide, a water playground, a water cave for children and a giant whirlpool for up to 30 people. There are also diving towers, an intensive salt water floating pool with underwater lighting as well as an underwater concert hall.

The Troldtekt acoustic panels absorb sound and go well with the overall design.

The minimalist exposed concrete design combined with wood and stone elements is elegant and expressive. Large, partially sloping concrete structures subdivide the areas on the ground floor, creating striking spatial scenarios.

The building’s open ceiling design allows even more light to enter in addition to the large windows.

The Troldtekt acoustic panels absorb sound and go well with the overall design, thus fulfilling a key role. Adding colourful highlights in green, red and black, they contrast beautifully with the light walls and floor.

Troldtekt Accoustic Ceiling

Acoustic ceilings in swimming pools

Shhh.

To be successful in offering relaxation, the quality of the building materials used along with attractive facilities is crucial.

Ceiling and walls clad with Troldtekt acoustic panels effectively absorb the sounds of splashing, shouting and playing, thus contributing to pleasant acoustics in swimming centres.

Escape from everyday life and experience relaxing moments. This is what today’s guests expect from an indoor swimming pool. To offer this, not only attractive features are required – the quality of the building materials used also determines the well-being of the guests and thus the success of the pool.

Ceiling and walls clad with Troldtekt acoustic panels effectively absorb the sounds of splashing, shouting and playing, thus contributing to pleasant acoustics in swimming centres.

Cement-bonded wood wool panels are also durable, with a natural resistance to moisture. The flexible design options also offer considerable architectural freedom.

Choosing materials is a particularly challenging process for architects designing swimming centres. Of course, the materials have to aesthetically match the architectural idiom. But a number of functional requirements also need addressing.

Swimming centres are usually large spaces, high-ceilinged and with many glass or concrete surfaces. In combination with the excited shrieks of children having fun in the water, this calls for acoustically exacting solutions. It is therefore important that the large ceiling and wall surfaces are clad with materials that have a high absorption coefficient – so they effectively soak up the sounds.

Environments with constant high humidity also place additional demands on the strength and moisture tolerance of the materials. Finally, the expansive walls often need a very carefully conceived visual design.

Troldtekt panels are chosen for many swimming centres – and outdoor baths – because the natural advantages of the cement-bonded wood wool panels perfectly match the requirements. You can read about five reasons why Troldtekt is an ideal choice below.

Cement-bonded wood wool retains the essential qualities of the components used to produce it – the strength of cement and the natural breathability of wood.

Superior acoustics

The open structure of Troldtekt acoustic panels absorbs sound effectively. The result is shorter reverberation times, minimising unpleasant noise – in the swimming pool areas and in the associated facilities (changing rooms, café etc.).

>> Read more about good acoustics

Natural strength

Cement-bonded wood wool retains the essential qualities of the components used to produce it – the strength of cement and the natural breathability of wood. Troldtekt acoustic panels are moisture-tolerant and therefore extremely suitable as acoustic ceilings in wet rooms. The panels cannot rot and do not attract fungal growth or other microorganisms.

The Danish Technological Institute has documented that Troldtekt acoustic panels are suitable for installing in rooms with:

  • moisture levels of up to 98 per cent (+/- 2 per cent)
  • high temperatures of up to at least 40 degrees.

Troldtekt has thus achieved the highest CE marking level (D) for water resistance.

The documentation shows that Troldtekt is a robust choice for even the most humid and warm rooms such as swimming pools, shower rooms and wellness departments.

>> Read more about natural strength

Effective fireproofing

Wood alone is an organic and flammable material, but every single wood fibre in a Troldtekt panel is encapsulated and protected by cement. Troldtekt panels are therefore fireproof without the use of any fire retardant or dangerous chemicals.

Troldtekt acoustic panels are fire classified under European standard EN 13501. Troldtekt acoustic panels are classified as B-s1,d0, which denotes the material’s reaction to fire. In practice, this means that Troldtekt panels are only weakly combustible and weakly heat and smoke-emitting.

>> Read more about effective fire protection

Troldtekt panels can be used to create a unique look on large ceiling and wall surfaces, adding to the whole as sound-absorbing design elements.

Flexible design

Troldtekt panels offer a number of different design options. Through special installation, colours or CNC machining, the panels can be used to create a unique look on large ceiling and wall surfaces, adding to the whole as sound-absorbing design elements.

Troldtekt design solutions come with the same great technical properties as the classic Troldtekt acoustic panels.

>> See the design options

Documented sustainability

Troldtekt is certified in the silver category under the internationally recognised Cradle to Cradle scheme.

The certification was attained in part because the panels contain no substances that are harmful to humans or the environment. They can therefore return to the biological cycle as nutrients, or to a technical cycle as a raw material in cement production.

 

Ramboll has also outlined how Troldtekt specifically contributes points to areas such as total cost of ownership, indoor climate and materials in the leading sustainability certifications – DGNB, LEED and BREEAM.

>> Read more about documented sustainability

Simple installation

Troldtekt panels are installed directly on battens on ceilings and walls or using profile systems such as suspended ceilings – with concealed or visible profiles. When installing the panels, only a few screws are needed per panel. There is no need to use filler or paint after installation.

The Troldtekt series includes specially designed screws that match the panels’ standard colours and structure. If you choose Troldtekt panels in custom colours, we can supply extra paint so you can dab the screws in the same colour.

Lochau Lido

Lochau Lido

Here comes the summer

Relaxed presentation of construction and material at Lake Constance.

The Lochau Lido is one of the most beautiful on Lake Constance. Between water and landscape, it has the appearance of having always been there.

In the spatial field between jetty and new mouth of the Kugelbeerbach brook in the Austrian municipality of Lochau at the Lake of Constance sits the flat, one-storey Lochau Lido building, right between lake and landscape. Rest and activity zones are kept close to the  building, leaving generous areas for bathers. Long boundary walls along the cycle path give structure to the surrounding space, defining a safe, identifiable area for parking bikes and guiding visitors to the widely roofed entrance area.

Lochau Lido’s wide, protective roof, covering various infrastructural units, also serves as a gentle mediator between the building’s indoor and outdoor areas. Entrance area and shop/cafeteria form one unit, accessible from both street and lake side. The spacious terrace of the cafeteria is separated from the lakeshore by a slight difference in height with wall fencing that still keeps access barrier-free for both bathers and guests.

On the opposite side of the main entrance, in an economical sequence of zones, are changing, wet and locker areas. Short distances and compact arrangement of organizational units characterize the building’s infrastructural core.

The laid-back presentation of construction and material characterizes the new building, appearing so natural.

Subtle, delicate architectural features and the direct expression of construction and materiality shape Lochau Lido’s character. The accompanying wall panels along the cycle path provide stability. A simple wooden building is positioned in this frame, its light structure reminiscent of a summery arbour. The immediacy of expression and its simplicity give the building a summery, laid-back charm.

Technical units are positioned on the roof above the respective room units, allowing for short distances and highly efficient operation. Clad in a galvanized steel mesh, the integrated technical equipment takes a back seat, clearing the stage for a striking, identifiable, emblematic new orientation point on the lake.

In connection with the architecture, which is so clear, the Lochau Lido is another attraction on Lake Constance.

When planning a building that is used only in summer, the choice of material is obvious. And so is, in terms of consistency, the choice of its load-bearing structure. A large, flat wooden panel as a roof, mounted on a layer of beams, supported by a central spine of small walls of solid cross-laminated timber and a wide downstand beam. Then, slender outer columns, each with an equally slender downstand beam. 

All technical and electrical systems are placed in an additional roof structure, a light steel skeleton frame resting on the roof slab on some points. The aesthetic qualities of the timber construction mentioned above make any cladding unnecessary.

Lochau Lido shows a very lean and thus highly economical construction.

We did this.

Rulantica

Silent giant

The Rulantica indoor water world

Advertorial

 

 

pbr & Troldtekt Acoustic panels

Situation

The incomparable Rulantica fairy tale water world in Baden-Württemberg offers adventurous and extraordinary aquatic fun for the whole family. The gigantic water park with an area of 40,000 square metres is located in the immediate vicinity of Europapark Rust, Germany’s largest amusement park.

Embedded within 450,000 m² premises, which also includes a hotel, the magical Scandinavian water world comprises nine elaborately themed areas that are populated by fantasy creatures such as mermaids, trolls and sea monsters.

Rulantica’s attractions include 17 water slides, the largest wave pool in Germany, a flow channel, several water playgrounds for different age groups and waterfalls.

Rulantica

Behind Rulantica’s imaginative and mystical scenery there is also a diverse story based on the youth book series with the same name by Michaela Hanauer. The story tells about the orphan Mats and the mermaid Aquina from the mysterious island of Rulantica in the North Sea.

The park’s interior comprises a 32,000 m² large hall that is 20 metres in height, the shape of which is reminiscent of a shell. It is traversed by one of the largest wooden roofs in Europe, made of natural wooden trusses (spanning up to 50 metres) and supported by five circularly arranged concrete columns with a diameter of 1.20 m.

Construction

A complex ventilation concept ensures that inlet air flows in from above and the air is drawn in at the lower area of the hall. The technology was installed in specially developed wooden framework boxes. In this way, pollutants are optimally removed from the water surface.

The main facade is divided into five 33-metre-wide elements by facade towers. With their filigree steel and glass constructions, they allow a noticeable amount of daylight into the hall.

pbr

Ceilings

The fact that it is surprisingly quiet in the impressive Rulantica bathing world is, on the one hand, due to the many rocks and decorative elements, and, on the other hand, due to the Troldtekt acoustic panels built into the ceiling.

The panels, which are suitable for damp rooms and made from the 100 percent natural building materials wood and cement, are characterised by excellent sound-absorbing properties. The acoustic panels were also installed in the heavily frequented foyer and in the changing room area.

Isfuglen

Hot and cold with a view

The Isfuglen winter bathing club

Advertorial

 

 

Matters & Troldtekt Acoustic panels

Situation

The winter bathing club “Isfuglen” (Kingfisher) at Brøndby harbour has created a great clubhouse. Club members can enjoy cold goosebumps, hot saunas and a cosy get-together here.

With its jetties, yachts and leisure activities, Brøndby harbour is a charming meeting place for residents living south-west of Copenhagen. Almost all of the many small wooden houses are painted red. The Isfuglen winter bathing club has also taken up the tradition of rust-red wood.

Identity

At the very edge of the harbour construction, the wooden structure catches the eye and welcomes everyone who enters the harbour by boat.

Its opening to the water is one of the many qualities of Isfuglen. From the large terrace that connects the clubhouse with the main pier, members can enjoy the view of the open Baltic Sea. There are benches here that invite you to linger.

Programme

Inside, Isfuglen offers club members access to a sauna with a panoramic view of the sea and the horizon. Further facilities are of course changing rooms, showers and toilets.

The main room with a kitchenette is generously dimensioned and warm. The walls are made of plywood, the ceiling has Troldtekt acoustic panels as cladding. Winter bathers like to meet here for morning coffee.

Atmosphere

The large windows and glazed doors allow for close contact with the harbour and the sky above. The room is flooded with daylight and the created atmosphere is fantastic.

The wood and the Troldtekt panels underline the warm atmosphere and create great interior acoustics. The interior appears simple and complex at the same time. This is due to the fact that the ceilings reflect the shape of the small gable roofs with which the wooden house ensemble is covered. A mirror wall reflects the great view of the building’s interior. Inside and outside become one.

We did this.

Ernst Ulrich Tillmanns

A day at the sea

Ernst Ulrich Tillmanns on constructing swimming pools

Introduction

Imagine diving into cool, clear water under a blue sky on a warm summer’s day – as Die Fantastischen Vier (The Fantastic Four) describe in their song “Ein Tag am Meer (A day by the sea)”.

“Du spürst die Lebensenergie (You feel the energy of life)
Die durch dich durchfließt (That flows through you)
Das Leben wie noch nie in Harmonie und genießt (Life like never before in harmony and you enjoy it)
Es gibt nichts zu verbessern (There is nothing that can be improved)
Nichts was noch besser wär’ (Nothing that could be even better)
Außer dir im Jetzt und Hier (Except you in the here and now)
Und dem Tag am Meer (And the day at the sea)”

It is precisely this experience of a refreshing swim outdoors that Ernst Ulrich Tillmanns and his colleagues from 4a Architekten strive for when designing swimming pools. 4a Architects have already designed, built or renovated numerous swimming pools in Germany, Austria and Russia – and have won several prizes in the process.

Each swimming pool is different

“Good swimming pools combine efficient functionality with an inviting atmosphere,” says Ernst Ulrich Tillmanns, managing director of 4a Architects. “Every swimming pool is different. No matter whether you are building a modern wellness club from expensive materials or renovating a simple swimming pool from the 1960s. It is always possible to come up with a good design in which guests feel comfortable. First and foremost, the bathing facility’s functionality and the atmosphere have to be observed.

Essential design elements are light and colour, with which different areas can be accentuated.

Avoid slaughterhouses

In order for the building to fulfil its intended function perfectly, all areas must be connected and well organised. Guests should find their way around with ease, the available space must be used optimally.

“It is very important not to waste space and to ensure that the design is as transparent as possible. If you start planning early, you can save a lot of money,” says Ernst Ulrich Tillmanns. “The atmosphere of the building is just as important. Some older swimming pools, like slaughterhouses, have white tiles and therefore look rather cold. Instead, it’s better creating a warm and inviting feeling of wellness. Therefore, choosing the right materials is crucial.”

Wood and water

Ernst Ulrich Tillmanns has his favourite among the available materials: wood.

“There is a lot of water at ground level. Tiles and concrete are preferable there. But a metre above that, wood is a very good material, both for the walls and ceilings. It is a natural material that does not corrode, lends a great atmosphere and is resistant.”

In the form of ceiling tiles, wood also ensures pleasant acoustics, which is a very decisive factor for a swimming pool to become a success.

Nature at the pool

Ernst Ulrich Tillmanns speaks up for an architecture that brings nature into the interior of the building.

“Since we humans prefer swimming outdoors, it is important to create the impression that you are being active outdoors. This can be achieved with large glass surfaces that create a visual connection between the interior and exterior. Other options are light colours and wood wool to carry the outside atmosphere inside. We did this, for example, when renovating the Lochenbad, a smaller swimming pool from the 1970s. With bright green acoustic panels and large glass surfaces, it seems as if bathers are immersed in a natural landscape”.

The importance of acoustics

Wood wool should not only create a natural atmosphere. Ernst Ulrich Tillmanns emphasises the importance of acoustics in the pool area, especially when large glass surfaces are part of the room that is already dominated by hard surfaces.

“It is very important to use acoustic materials for the ceilings. People should be able to have fun and relax. A pool area with poor acoustics is bad for the brain. I once visited an older swimming pool with a large glass dome over the swimming pool area. The noise level was almost unbearable.”

Variety

He concludes: “If materials enable variety of design in addition to acoustic properties, this offers us architects great potential.

One example is the recently opened water and leisure park in Kusel. The coloured ceiling elements in particular lend the building a special charm. With their colour scheme, which is based on a colourful field of flowers, they lend the indoor pool a cheerful atmosphere and, last but not least, its own identity.”

Kusel swimming pool

Not everybody has this

Kusel swimming pool

 

 

 

4a Architects

Situation

In order to enable bathing to continue economically, the existing bathing landscape of the Kusel swimming pool – Vitalbad Kusel – needed to a very large extent to be deconstructed and rebuilt.

The aim of the design was to develop the functional new construction as an attractive landscaped bathing area with a high quality of space in which to spend time and a distinct character and to make maximum use of synergy effects.

Kusel

The municipality of Kusel nestles scenically in the natural region of the Palatinate Uplands and with 5,400 inhabitants it is Germany’s second smallest district town. The Vitalbad aquatic and recreational park is located at the north-western edge of the town.

The aim of the redevelopment of Kusel swimming pool was to increase the attractiveness of the aquatic park and to increase the feel-good factor as weil as bringing the baths technically up to date.

Original

The original single-storey building was organised for classic bathing from east to west. comprising a foyer with catering facilities, changing areas and a bathing hall with pools for non-swimmers and for swimmers, diving towers, a slide facility and an outdoor pool accessible from indoors. The outdoor pool area with outbuildings and sunbathing lawns used to be adjacent to the south.

In order to enable economic bathing in future, Kusel swimming pool had to be almost completely stripped down to the bathing platform. Only the basement and the slide tower were retained.

All the parts of the existing building were stripped back to their shell and provided with new surfaces on the floor, wall and ceiling.

Aims

The basis for the alignment and design of Kusel swimming pool was the existing basement on which the new building was erected. The shape and geometry of the swimmers’ and non-swimmers’ pools were retained in the existing building but were re-tiled and the diving facility was replaced.

The aim was to keep the shape of the building as compact as possible and to optimise the functional procedures, for example in order to be able to staff the pay desk and catering area with only one person during off-peak periods.

Structure

Due to greater roof loads, the existing spatial framework was replaced with a frame construction consisting of welded double-T steel girders. The white steel girders are positioned in a transverse direction to the building and span across the entire width of the building.

A wooden substructure with suspended lightweight wood-wool boards ensures excellent acoustics within the building and lends a summer-fresh ambience to the interior space. In order to reduce the volume of the building, the height of the building was adapted to the use of each area as part of the redevelopment.

Ceiling

The ceiling height of the ancillary rooms is lower compared with the bathing hall, while the roof in the diving area turns upwards.

In addition, the façade was repositioned outwards so that the supports for the steel load-bearing system stand inside the building. This prevents the energetically disadvantageous penetration of the outer skin while additional surfaces are gained.

Functionality

The entrance to the indoor and outdoor pools remains on the south side of the building. Along the glazed entrance façade, a roof overhang provides a protected outdoor area towards the outdoor pool.

Via the transparently designed foyer with a catering area, bathers gain their first views into the bathing area and reach the bathing hall via the changing areas and sanitary facilities. Structurally, the ancillary rooms form three cubes with rounded edges between which there are passageways with visual axes towards the bathing hall.

Design

A brightly coloured design runs throughout the whole building. The fresh ceiling design in particular gives Kusel swimming pool a unique identity and a cheerful atmosphere. In contrast to this, the wall and floor surfaces were designed in calm, dark shades.

The additional bathing offering with a new children’s area and hot whirlpool and the extended recreational and reclining areas likewise increase the welcoming quality of the new aquatic park.

Outdoor area

The water surfaces in the outdoor pool area were reduced in order to make the running of the baths more economical. There is no need for a non-swimmers’ pool and, with four lanes, the new stainless-steel swimmers’ pool is smaller than in the original construction.

The recreational pool remains in the original structure after the redevelopment of the pool border and surroundings.

Additions

A new outdoor children’s pool and a mud area were added for younger bathers. A new changing building was also added constructed as a cold building. The kiosk between the swimmers’ pool and the slide facility remained in the original building.

The basement had tobe structurally extended for the technical installations of the indoor and outdoor pools.

Budget

The tight budget for the redevelopment of Kusel swimming pool is reflected in certain parameters, for example the volume of the building, the water surfaces and also, in part, the design of the surfaces.

lrrespective of this, it was possible to form the indoor and outdoor pools as a unit in terms of design and functionality and to give the new Vitalbad a brightly coloured radiance and an identity of its own.

We did this.

Jamsil Hangang Park

Curving & connecting

Jamsil Hangang Park in Seoul

100 Architects

About

A creative international collaboration between 100 Architects (Shanghai), Carve (Amsterdam) and Urien (Seoul), with the local coordination & support of the landscape architect Walter Ryu, has resulted in this proposal for a leisure facility in Seoul, South Korea.

Bring back the glory

With the purpose of improving the existing public facility of the Swimming Pool in Jamsil Hangang Park, the Municipality of Seoul launched a competition for a design solution that would bring back the former glory of this 30-years-old facility on the banks of the Hang River.

Not only by renovating the Swimming Pools themselves, but also seeking a solution that would reactivate the entire Park as a public destination within the City of Seoul.

Bring back nature

Our mission transcended the renovation of the existing pools, targeting the reestablishment of the natural landscape and fulfilling an entire urban regeneration, turning Hangang Park into a major urban and ecological landmark for the city of Seoul, to be used throughout all seasons.

The proposal unifies the pool complex with the surrounding cultural facilities. On the West, the Sagak Sagak Artistic Area, and on the East, the Botanical Learning Center. The plan connects those 3 facilities through a system of meandering interweaved pedestrian paths, allowing easy pedestrian accessibility between all of them, transforming the entire riverfront into a prominent public natural destination.

Taegeuk

The joint proposal draws its inspiration from Taegeuk, the traditional Korean symbol which can be found in the National Flag of South Korea, as a very honored, loyal illustrative and recognizable shape. A perfect circle split in two halves, red & blue, representing the balance in the universe.

The search for this balance between nature & architecture, is the core of our design, translating the Taegeuk into a circular architectural object, a pedestrian walkway that encloses the main pool facility. This circular walkway is interrupted at the riverbank, hovering over the river, a belvedere allowing amazing views over the Hang River.

The walkway

Curving upwards towards the highway, the elevated pedestrian walkway shields the pools from the traffic noise. At the same time, it accommodates necessary indoor facilities under its roof.

It flattens at the intersection with the riverfront promenade, in order to ease pedestrian connectivity; and finally, it protrudes over the riverbank, creating two walkable piers overlooking both, the river and the restored nature of the riverbank.

Valuable interaction

The undulating intertwined pedestrian paths create opportunities and affordances for the park’s public program. Programmatic interventions for entertainment and leisure spaces within the natural environment are envisioned, offering valuable interactions with nature. Spaces for practicing a wide range of sports, resting areas, shading structures and natural kids playscapes, resulting in a multifunctional park suitable for all kind of ages.

All pools are designed in a sustainable way to naturally clean its water by using a helophyte filtering system with reeds planted around the pools. The treatment of cleaning the water is naturally done by bacteria living in the roots of the planted reeds.

We did this.

Paracelsus Bad & Kurhaus

Naked in Salzburg

Paracelsus Bad & Kurhaus

Berger+Parkkinen Architekten, Agrob Buchtal

About

The Paracelsus Bad & Kurhaus, which opened in the 4th quarter of 2019, is already exceptional because it is located in the middle of the city of Salzburg (Austria) as a five-storey spa, bathing and sauna world. In addition, the architects from the Viennese office Berger+Parkkinen created an impressive building sculpture which offers a high degree of security despite its extensive openness.

Wall and floor tiles of the Savona series of Agrob Buchtal play a key role in this.

Situation

The new Paracelsus Bad & Kurhaus is located on the edge of Salzburg’s old town, which is protected as a UNESCO World Heritage Site – directly next to the spa gardens and Mirabell Castle, where people have been bathing and recovering already for more than 150 years.

Continuing this tradition was one of the most important goals of the City of Salzburg when it decided to demolish the outdated previous building from the 1950s and replace it by a new building with an enlarged range of facilities.

Three areas

Anyone approaching the new building from the spa gardens will come across a slightly curved monolithic structure, whose cladding of vertical marble-white ceramic lamellar elements provides extensive openness at the same time. “It is only at second glance that you become aware of the classic building division into base, beletage and upper floor”, says architect Alfred Berger.

Base floor

The gymnastics, massage and therapy rooms of the Kurhaus as well as the entrance and changing rooms of the swimming pool and sauna area are located on the three levels of the base floor.

Behind the glass facade of the beletage, the ceiling of the swimming hall, modelled as a gently undulating spatial sculpture, is clearly visible. Above it are the pool and sauna restaurant as well as the sauna area with four saunas, steam bath and roof terrace with Infinity Pool.

Arrival

The fact that the architects have succeeded in creating a uniformly designed building despite independently articulated areas is already evident in the entrance hall. The focal point is a wide “stairway to heaven” with marble-white terrazzo steps and landings, which seems to lead straight under the undulating ceiling of the swimming hall.

Only when one has reached the cash desk on the 2nd upper floor leading to the bathing and sauna area, the large fixed glazing separating the entrance area from the bathing world becomes visible.

Changing areas

After the access control, the visitors first enter the changing area, whose changing cubicles, striped in light green and blue, are reminiscent of airy beach chairs by the sea.

The 60 cm long porcelain stoneware tiles from Agrob Buchtal’s Savona series, laid alternately in 20 and 30 cm wide strips on walls and floors, also fit into this picture. Their lively, moving surfaces in the shade of lime, together with the irregularity of the free bond, create a secure, earthy-warm room atmosphere.

Stairway to heaven

Via the upper part of the “stairway to heaven”, the bathers finally reach the swimming hall with diving platform, sports, children’s and family pool. This staircase opens up visual references to the entrance hall as well as to the changing and bathing areas and thus significantly facilitates orientation in the building.

It is particularly impressive when bathers arrive at the large, light-flooded swimming hall on their way up – as if “emerging” directly from the ground. There, they not only find a spacious bathing landscape with a seemingly weightlessly meandering suspended ceiling, but also a variety of views of Salzburg’s old town and the spa gardens.

Colour composition

A contrast to this overwhelming spectacle of nature and forms is the restrained colour and material concept of the bathing landscape. The sand-brown or white surfaces of the walls and the ceiling are predominant, as are the floors, which are also completely covered with lime-coloured tiles from the Savona series.

Thanks to the same size, colour and laying method as in the changing room and the upper “stairway to heaven”, the entire changing and bathing area appears as a coherent space continuum.

The only and thus determining colour accent is provided by the water basins glowing in light turquoise, which are atmospherically reminiscent of the many crystal-clear mountain lakes in the vicinity of Salzburg. This effect is based on 12.5 x 25 cm wall and floor tiles of the Chroma Pool series in the shade of medium turquoise. “The glaze makes the water appear in a natural way as if it were shimmering by itself”, explains Berger.

View of the Mönchsberg

As an integral part of the space continuum of the bathing landscape, the entire floor of the sauna area on the 5th floor also has porcelain stoneware tiles from the Savona series laid in strips, there however in the colour anthracite. This colour perfectly harmonizes with the wood-covered walls, but also refers to the dark, rugged Mönchsberg rock, one of the landmarks of Salzburg’s old town.

The tiles are not only to be found in the access and rest areas, but also as an architectural link in the showers and in the saunas, some of which are oriented towards the glass facade. “The possibility of being able to use Savona anywhere in the swimming bath in principle – on the floor and walls as well as in the water and in the sauna – was decisive for us when it came to selecting a suitable tile”, says Berger.

Infinity Pool on the roof terrace

In both senses of the word, the highlight of every sauna visit at the Paracelsus Bad & Kurhaus undoubtedly is the outdoor pool on the southern roof terrace, designed as Infinity Pool. A small part of the pool serves the sauna guests as a cold plunge pool, while the rest is designed as a 32° warm brine pool.

Thanks to the raised pool on the roof surface with elevated water level and a low overflow channel on the outside, the view of almost the whole of Salzburg is unobstructed.

The gently rounded pool edges and the anthracite-coloured 5 x 5 cm mosaic tiles of the Chroma Plural series create a delicate small-scale structure conveying a feeling of security and well-being in the pool, which is designed as a nude bathing area. 

Conclusion

Even though the building opens to the city in many places, this feeling of security can be experienced everywhere. It is created not least by the pleasantly consistent design concept, which is based on natural colours and materials and thus offers an intuitively sensual bathing world – an important aspect in a place where people meet in vulnerable nudity.

The Paracelsus Bad & Kurhaus offers great gestures and finest details. It offers its guests a wide range of services in many different areas. Through the skilful combination of flowing floor plans and rich materials, it is an extraordinary experience in every space.

Hubertus Pool

Eye in the sky

Hubertus Pool Olang

noa* network of architecture

Hotel Hubertus

The Hotel Hubertus is located in Valdaora, at the foot of the famous ski and hiking area Kronplatz in the Puster Valley at an altitude of about 1350 m.

The family establishment was generously enhanced and enlarged with 16 new suites, a new kitchen with restaurants and “Stuben”, an entrance area with lobby, reception and wine cellar and a fitness and a relaxation room with panoramic terraces.

The new 25 m long pool, functioning as a connector between old and new, underlines the essence of this comprehensive renovation and renewal project.

Hubertus Pool

The new Hubertus Pool, which imposingly rests in-between the two accommodation wings, seems like a floating rock, come to rest at the site, overlooking the valley. The hidden edges of the pool, kept in anthracite-coloured stone, abolish the gap between pool and landscape, creating the impression of the water flowing into nothing, disappearing between pool and landscape.

The pool metaphorically reminds of a mountain lake, nestled into the astonishing mountainscape of the UNESCO World Heritage site, the Dolomites.

Challenge

The key challenge in the project was to create a link between the existing building and the new design, in order to keep a uniformal and consistent appearance. The debarked larch trunks, which were used as multifunctional façade elements for the existing and new building, succeed in creating this aesthetical connection. The multifunctional façade elements of debarked larch trunks create an optical link between existing and new, maintaining the homogeneous appearance of the project. They not only support the dynamics of the curved façade, but function also as sunscreens, room dividers and rain protectors, further enhancing the feeling of privacy and in addition to this forming the static basis for the cantilevering pool and façade.

Floating

Hubertus Pool is floating like a natural rock over the new accommodation wing. Without any visible boarders, a width of 5 m, a length of 25 m and a depth of 1,30 m the over 17 m cantilevering pool can be seen as completely unique.

The position of the pool, which floats 12 m above the ground, at its extreme edge, gives the swimmer the feeling of floating – weightlessly between heaven and earth. This impression is further reinforced by the glass front and a glazed window on the bottom of the pool.

We did this.
