Hej roof space

Designers and building contractors have recognised the potential of space on the roofs of our cities. In a few decades, our roofs will be landscapes.

With its green façades, multi-purpose use and, above all, roof space that has been capi­ta­lised on, IKEA Vienna West­bahnhof is much more than just a furni­ture store – it is a new meeting spot in the heart of the Austrian capital.

Along­side the façades, the roof is the building’s special feature. The huge roof terrace offers not only a magni­fi­cent view over Vienna, but also versa­tile offers for the public – and a chall­enge when it comes to sound insu­la­tion.

Desi­gner and buil­ding contrac­tors have reco­g­nised the poten­tial for space on the roofs of our cities. In a few decades, accor­ding to Jakob Dunkl from quer­kraft archi­tekten, our roofs will be “land­scapes that will be inha­bited, used and greened” – so, a very big topic for the future.

The façades and roof are exemplary and pioneering, especially when it comes to climate protection and the increased requirements for sound insulation.

 The archi­tec­ture and the possi­bi­li­ties of use are always crucial factors for a buil­ding’s success, and quer­kraft archi­tekten have done a lot of work here. They created a highly commu­ni­ca­tive struc­ture with urban spaces for expe­ri­ences and active roof surfaces.

A green mantle surrounds the entire buil­ding. It is 4.5 metres deep, provides plenty of shade, and houses rooms, terraces, plants and lifts, emer­gency stairs, toilets and buil­ding services.

The façades and roof are exem­plary and pionee­ring, espe­ci­ally when it comes to climate protec­tion, intel­li­gent urban conso­li­da­tion and the increased requi­re­ments for sound insu­la­tion.

The building is in line with the positive image of the furniture store, and yet this branch is different from all the others that have gone before.

IKEA wants to be a good neigh­bour, so the buil­ding also looks extre­mely friendly, uncon­ven­tional and urban. The Swedish furni­ture store uses five of the seven floors. Hotel Jo & Joe is located on the top two floors.

The buil­ding is in line with the posi­tive image of the furni­ture store, and yet this branch is diffe­rent from all the others that have gone before. On each level are open spaces with plants, greened façade elements, birds’ nests, beehives and lots and lots of light. A total of 160 trees ensure a more plea­sant micro­cli­mate.

IKEA Vienna West­bahnhof is crowned by an attrac­tive roof space with offe­rings that make a diffe­rence. The roof and buil­ding have already been awarded the GREENPASS ® Platinum certificate.This is an equally ambi­tious, new, all-in-one plan­ning and certi­fi­ca­tion tool for climate-resi­lient urban plan­ning and archi­tec­ture.

Everyone involved is a winner: those who meet for coffee on the spectacular roof often also visit IKEA, and vice versa.

IKEA and quer­kraft archi­tekten have reco­g­nised that capi­ta­li­sing on roof areas is a huge oppor­tu­nity to made our proper­ties, and thus our cities, more attrac­tive: the IKEA “TOPPEN” snack bar on the roof terrace is the first in the world that is publicly acces­sible. But there is no compul­sion to consume – you can also bring your own snacks.

Ever­yone involved is a winner: those who meet for coffee on the spec­ta­cular roof often also visit IKEA, and vice versa. Those who want to stay the night in Vienna also choose their accom­mo­da­tion based on the offers in the surroun­ding area – and the terrace on the roof is open until the evening.

This combination of lively living and bedrooms below naturally entails requirements for compliance with maximum sound insulation.

REGUPOL is the right partner when it comes to deve­lo­ping holi­stic urban solu­tions, and also when it comes to the absence of conflict between the various user concepts.

The roof terrace above Hotel Jo & Joe is open to the public until late in the evening. This combi­na­tion of lively living and bedrooms below natu­rally entails requi­re­ments for compli­ance with maximum sound insu­la­tion (target value LnT,w< 28 dB accor­ding to ÖNORM S 5012:2012).

The impact sound insu­la­tion that is suitable for the outdoor area of IKEA Wien West­bahnhof not only meets all the sound insu­la­tion requi­re­ments but also protects the sound­pro­ofing against mecha­nical influences and has a drai­nage func­tion. A filter fleece for preven­ting slur­ries ensures these proper­ties on a perma­nent basis.

To put it in the words of the architect: “If you love something, it stays for longer.”

IKEA Vienna West­bahnhof is brea­king new ground on many levels. On the one hand, the Swedish furni­ture store is taking account of chan­ging consumer beha­viour with a new, car-free concept, and, on the other, thanks to nume­rous archi­tec­tural and tech­nical ideas, it offers enormous struc­tural sustaina­bi­lity.

Yet, the plea­sant and authentic appearance of the buil­ding, the gree­nery and the capi­ta­li­sa­tion on the roof areas (yoga courses are even held here) also give it emotional sustaina­bi­lity. To put it in the words of the archi­tect: “If you love some­thing, it stays for longer.”
