The single-span hall is used by the primary school and local associations mostly for sporting activities.
Due to significant cracking in the timber structure, the integrity of the roof structure was called into question and needed to be replaced.
In order to stabilize the building`s structure and to increase the seismic safety, a new equipment room was added. All components to be replaced were planned in accordance with current energy standards. So far, unresolved functional problems such as inadequate natural ventilation, lack of flues and of visual contact to the outside, resulted in revised drawings. The gym`s profile is relatively flat and therefore hardly appears in the city's skyline. The old flat-pitched hipped or gable roof with red tile roofing did not fit optically with the height of the building and was rethought entirely.
The new extensive green roof panel mirrors the natural terrain of the vineyard and the building “huddles” against the slope.
The new façade with the entrance, consisting of copper diamonds and facing the school building, will be more noticeable than the older, as the previously very deep-set eaves side turns into a gable wall. Thereby the connection of the sports hall to the enclosing walls of the theater basement is improved.
The ridge turret allows for the required natural lighting, ventilation and smoke extraction of the hall. Domes and skylights typical of sport halls can be avoided.
