Exercise and Socializing
The Schönberg Sports Hall

Three years of construction, an investment of 18 million euros, and a vision that goes far beyond traditional school sports: With the new Schönberg Sports Hall, a sports center has been created on the campus of the Probstei Comprehensive School that combines architecture, functionality, and sustainability.
The hybrid wood construction, the striking lighting design, and the exceptional amenities—including permanently installed gymnastics equipment—make this new building a landmark project.
A New Center for Exercise and Socializing
The new sports hall on the campus of the Probstei Comprehensive School in Schönberg replaces an existing facility that could no longer be renovated for economic reasons and provides far more than just new space for physical education classes. The result is a multifunctional sports center that brings together the school, sports clubs, and the public, and views sports as a social gathering place.
The scale of the project speaks for itself: The municipality invested around 18 million euros in the new building, the completion of which was celebrated after about three years of construction. For the approximately 1,500 students, this means one thing above all else: Physical education classes are once again held indoors—regardless of the weather or season. After the old gym was lost, physical education classes had been temporarily moved outdoors, even in winter.

Flexible Spaces for Sports and Events
At the heart of the new Schönberg sports hall is a spacious three-court facility that can be flexibly divided into smaller sections using movable partitions. It is complemented by a separate gym with permanently installed equipment—a unique feature that significantly reduces the effort required for setting up and taking down equipment during the school day while also creating new training opportunities.
In addition, there is a fitness room and a two-sided bleacher system with seating for about 500 spectators. This means the gym can accommodate not only classes and club sports, but also competitions, sports festivals, and school events.
It is precisely this multi-purpose use that defines the facility’s operating concept: While school sports take center stage during the day, clubs take over the facilities in the afternoon and evening. In the future, the facility is even expected to host interregional competitions.


Architecture: A Balance Between Precision and Warmth
Architecturally, the new building is deliberately designed to stand alone as a freestanding structure. It blends into the campus without being subordinate to the existing buildings in terms of design.
The entrance area is designed as a minimalist exposed-concrete structure: robust, clean-lined, and understated. The hall areas, on the other hand, are enclosed by a slanted, perforated trapezoidal sheet metal façade. This creates an unusual sense of dynamism and makes the large structure appear lighter.
The wraparound band of translucent profiled glass is a particularly striking feature. It begins in the entrance area, accompanies visitors through stairwells and bleachers all the way to the fitness room, and extends around the entire building as a unifying element. The interplay with the perforated façade creates shifting effects of light and shadow that generate a unique atmosphere both indoors and outdoors.
This material strategy continues inside. Exposed wooden structural elements, wooden slat walls, wooden benches, and exposed concrete surfaces create a warm, natural spatial atmosphere. The choice of materials not only serves design purposes but also improves acoustics and wayfinding.

Sustainability as an integral part
In the planning and construction of the Schönberg Sports Hall, sustainability was not viewed as an additional measure, but rather as a fundamental planning principle.
The sports hall was constructed using a modular design with a high proportion of prefabricated elements. This made it possible to reduce construction time, material loss, and waste. At the same time, prefabrication enhances the precision and quality of the workmanship.
The chosen hybrid wood construction method combines the load-bearing capacity of reinforced concrete with the environmental benefits of wood as a building material. Many of the materials used are separable and largely recyclable—an important factor for later reuse or recycling.
The building also takes a clear approach to energy efficiency: an air-source heat pump, photovoltaic panels, and solar thermal systems cover a large portion of its energy needs using renewable sources. This is complemented by natural lighting and ventilation, which reduce the need for artificial lighting and mechanical ventilation. The new building meets the KfW-55 standard and thus significantly undercuts the energy consumption of conventional buildings.

More than just a gym
Sports facilities are increasingly viewed as infrastructure that fulfills social functions beyond their primary purpose. This concept was also incorporated into the planning for Schönberg. The Schönberg sports hall is fully accessible and can be used by people of all ages. At the same time, it can serve as a multipurpose or emergency center when needed—for example, during public events or for disaster response.
As a multifunctional sports center, this project combines a three-court gymnasium, a fitness area, and bleachers within a striking architectural design. Natural materials, sustainable building technology, and flexible usage concepts create a space for schools, clubs, and the entire community.
The result is a building in Schönberg that goes far beyond the traditional concept of a school gym: a place for physical activity, social interaction, and community—with architectural originality and a long-term vision.
