To strengthen the monolothic and natural character of the building, compressed concrete was chosen as the material for all 5 facades. A compact, pressure-tight material was produced by compressing layers of natural stone and cement of varying pigments. In the entrance, the spaces suspended above the open area are held in place by the glass facade's post construction. Elsewhere, the are reinforced with a slab system. The roof is made from insulated reinforced concrete.
The building's solid structure has an exterior wall thickness of 50-80 cm. The facade materials allow for a natural insulation in the building. All window elements are deeply recessed in the facade, creating a natural shade on the interior. The windows are also glazed for protection against solar rays.
The outer walls and a part of the roof are composed of compressed concrete. The use of this traditional method of material manufacturing - in which cement and natural stone are brought together in layers and compacted - bridges the gap between historical building methods and the contemporary building design. Furthermore, this material was chosen as it has a strong degree of regional and local relevance.
