Multipurpose Hall Rünenberg.

Following structural and economic assessment, the municipality of Rünenberg decided to replace the existing sports and cultural centre with a high-quality new building.

The replacement structure is a two-storey building, 36 m long and 30 m wide, consisting of a small basement with plant rooms and storage, a ground floor with foyer, multipurpose hall, community rooms and a kitchen, and an upper floor with changing rooms and additional sanitary facilities. A new access wing connects it to the school building.

Following demolition of the old gymnasium, the foundations were first constructed with lean concrete piles and the ground slab. This foundation was necessary because the upper soil layers of the site were not load-bearing and the loads therefore had to be transferred to deeper, load-bearing strata.

The support structure consists of a hybrid timber frame with timber-concrete composite floors above the ground floor and a timber beam roof. In the basement, solid reinforced concrete walls withstand earth pressure and moisture. The stairwell core is also of reinforced concrete. On the ground and upper floors, timber columns and timber stud walls of spruce were employed for vertical and horizontal load transfer. The roof was fitted with a PV system.
