Load-bearing structure with very short assembly time and fast weather protection

The 62 m x 22.5 m single-storey structure with a height of 10.4 m is built on an elastically bedded foundation slab made of reinforced concrete and is a pure timber construction from the upper edge of this foundation slab.

The load-bearing and bracing interior walls of the hall are constructed as cross-laminated timber walls. The exterior walls with the functions of load transfer and thermal outer shell are predominantly designed in timber frame construction, individual areas that have to be used to stiffen the building are also designed as cross-laminated timber walls.

The complex roof geometry with hips and ridges is represented by a conventional roof structure consisting of trusses, hip rafters and purlins as the primary supporting structure. The areas between the primary supporting structure are closed as roof elements in widths of approx. 3.00 m with a high degree of prefabrication. This enables a very short assembly time and rapid weather protection.

The external appearance of the multi-purpose hall takes up the character of the courtyard and barn roofs that characterise the area in its façade and roof shape as a large modern form and blends into the landscape as the northern edge of the village.

The large and small halls are accessed from the forecourt in the west via the foyer in front. To the east behind the large hall, in the centre of the structure, is the heart of the building, the stage with its ancillary areas. Behind it are the cloakrooms and the props store. Adjacent to the foyer in the northern area are the ancillary rooms such as visitor toilets, kitchen, staff and storage rooms. The east-facing room for the countrywomen, the changing rooms and the stage can be reached quickly via the southern side entrance for sports and club activities.

The multi-purpose hall with its contemporary, sustainable, open and transparent appearance in ecological timber construction using local timber to a large extent, both in the construction and in the extension, represents a valuable contribution to the townscape and club life of the sub-community of Geißlingen and the entire Klettgau region.

The special feature of the building is its floor plan, which is customised to the uses. The polygonal floor plan can be adapted to the size requirements of the various events by means of flexible partition wall elements that connect or separate the two halls and the foyer.

The suspended acoustic ceiling is adapted to the different roof pitches by folding the individual surfaces several times, so that optimum acoustics are created for concerts, for example.

To make optimum use of the building cubature, the ventilation centre was located above the changing rooms on the top floor. This meant that there was no need for a basement. In addition to reducing earth movements by not building a basement, the centralised arrangement also reduces the length of the pipes.
