The deep window reveals and the narrow column grid along the entrance side adopt its architectural stance and provide structural sun protection. The natural stone reappears indoors in the form of flooring and wall panelling, and in bathrooms as solid washbasins. The key theme in terms of material is the timber structure, visibly exposed to a major degree. The building measures 33 × 33 m, houses an auditorium and 13 classrooms, and can accommodate up to 1000 students. It was designed as a timber construction with as little steel as necessary. The remarkable ribbed ceilings meet high soundproofing requirements and consist of cross laminated timber slabs on top of glued laminated timber downstand beams spanning up to 9.20 m. This lightweight system can be simply disassembled as required. Soundproofing and thermal insulation both contain cotton sourced from recycled jeans, performing better than key values set by the Dutch circularity indexes BCI and MCI.
Shafts and ducts for building services were avoided as far as possible. A timber staircase with sculptural appeal is situated in a two-storey atrium in the centre of the building. The atrium vents air naturally. Ample daylight enters through shed roof skylights. The visibly exposed wood surfaces contribute to a comfortable learning atmosphere that fosters focused work. The building offers many different views of the surrounding park: spanning the entire lecture hall width in the north, filtered by natural stone slats in the east, and on the gallery level, framed by windows with deep reveals that double as benches.
