Competition Stadion Union Berlin

Berlin

UNION BERLIN is getting a new stadium on the same site—a historic location that has shaped the extraordinary closeness between the club and its fans. In Wuhlheide, situated between the Wuhle and the forest, a pure football arena has been in use for decades. The characteristic spatial proximity between the pitch and the stands is enhanced and atmospherically intensified in the proposed design through the geometry of the new structure.

A stadium transforms into a theater—a pitch becomes a stage— and the stands turn into seating tiers and boxes with areas for dining, merchandising, infrastructure, and more.

The new stadium is optimized for marketing capabilities (media/advertising) and third-party usage options (additional uses).

All spectator seats will be covered. The roof covering will be translucent, colored, and will thus serve as a signal. The roof membrane extends into the facade plane of the top gallery, creating the appearance of a floating, luminous object.

The primary structure consists of prefabricated reinforced concrete elements, while the roof framework is made of a steel truss with V-shaped supports and rear guy wires. This design ensures that all seating rows are free of supports and unobstructed. Lighting, sound systems, and drainage are integrated into the construction. The surfaces available for advertising are maximized and optimally aligned with camera positions. These include the perimeter boards, the interior and exterior edges of the roof surfaces, the surrounding areas of the upper and lower galleries, VIP boxes, and the exterior of the textile facade (which can display changing illuminated advertisements), among others. In addition to conventional camera positions, the upper gallery will serve as the main camera location, with options available at any point.

BVB Stadium

Dortmund

In the course of the ongoing modernization and flexibilization of the BVB stadium, which is increasingly intended to accommodate non-sporting events, BVB is considering combining the concept of a stadium with that of a multifunctional hall. This project is the result of a feasibility study.

During the ongoing match operations, the spectator capacity is to be expanded and the stadium extended with a roof that enables it to be used as an indoor arena.

Realized in several construction phases, parts of the existing building will be linked to the new components, realized with a maximum degree of prefabrication, enabling modular joining on site and at the same time significantly reducing the construction time. In order to protect the turf when the hall is in use and at the same time ensure the regenerative growth of the grass surface, the pitch itself becomes a roof. For this purpose, a shipbuilding technology is used: hydraulic heavy-lift systems, which are installed at four points in the stadium corners, raise the pitch by 40 meters within half an hour, where it will then fulfil the function of a roof. A seven-meter-high, walk-on steel grid forms its supporting structure and contains all the lighting and acoustic installations of a hall.

In future, the stadium will offer up to 80,000 seats for open-air sporting events. For music events under a closed roof, the capacity could be increased even further thanks to the available space inside.

Competition Suspension Railroad Kluse

Wuppertal

The Kluse suspended railroad station in Wuppertal, which was destroyed during World War II, is being rebuilt at its historic location near the Schauspielhaus theater. Since several urban pathways intersect at this point, Petersen Architects placed great emphasis on urban significance and integration in their station design.

The lower distribution level serves as an additional public space during the day, illuminated by the translucent platforms above. These platforms are made of slip-resistant, walkable glass [Litefloor].

The entire structural framework is divided into longitudinal planar structures, which are stiffened by compression pipes both at the platform level and above the tracks, as well as by cable tensioning. Each structural frame consists of a pair of cantilevered external supports, inclined in alignment with the frames of the track carriers. These supports bear the facade and are shaped according to their bending loads. Together with a story-high truss below the distribution level, they form a tensioned structural system.

In front of the single-glazed facade, perforated metal panels are hung at a distance, serving as glare and sun protection. The steel frames of these panels are mounted on sliding mechanisms and can be lowered down to the access level to lock and secure the station, giving the structure a different appearance at night.
