The hall has a rectangular two-bay layout and is 43x76 m on plan. The simple cubic volume is over 10 m high and accommodates two parallel gantries. The laminated timber columns at 6-metre centres are constructed in the form of Vierendeel trusses. Their relatively great depth and the rigid fixing of both chords in the foundations ensure optimum cross-bracing. The taller chord of the outer columns supports the roof construction, the lower inner chord bears a gantry rail. The roof loads are transmitted to the internal columns via a trussed girder. Between the chords of these columns is an access walkway. The roof construction is supported by a series of slender laminated roof trusses at two-metre centres. Longitudinal bracing is provided by steel crosses in the long facades, by laminated sheeting in certain areas of the roof, and by the longitudinal beams and gantry rails.
