The cubic content of the two-story office building of DATAflor AG, with approximately 900 m2 gross floor area, shows an arrangement of the office rooms around a massive core that serves as a plenum and workspace for flexible work. The building is linked to the existing structure via a connecting volume and was designed as a reinforced concrete skeleton with exterior walls in timber frame construction. A steel structure runs three-dimensionally around the perimeter as an escape balcony, which, with vertical larch wood slats, forms a filtration layer to the densely built surrounding area.
