The overall project school and sports facilities planning Neukirch includes as an essential component besides the new construction of a secondary school building the construction of a triple sports hall. The simply structured building consists of a nine metre high hall with three floors assigned to specific uses. The gymnasium is partly underground. The high roof loads (greenery, photovoltaics, roof sinks for skylights) are transferred via ceiling girders made of glued laminated timber to the concrete supporting structure below, which is characterised by exposed concrete surfaces. These girders rest on the 50m wide façade girder of the north façade, a wall plate running over the entire height of the hall and on the walls of the south façade. The adjoining rooms are spanned by conventional flat slabs, which rest on the space-enclosing walls.

Characteristics of the timber construction:

• Span of the timber beams: 32 m
• height of the double beams: 2.38 m
