With the design of a façade, architects want to create a spiritual and visual arch from the inside to the outside and back again. In the case of this business and company building, architect Marcus Frank has succeeded exceptionally well. For in a place where everything revolves around fire, fireplaces and tiled stoves, the reception should be as warm as possible, even from the outside. The flexibly cut Natural basalt slabs piled up to form a lively structure which is reminiscent of a pile of wood, give the building a correspondingly inviting effect. Natural has an unusual property: the initially fresh yellow-green colour scheme of the slabs gradually turns into a velvety, slightly sparkling brown-red surface. The effect is similar to the weathering process of certain types of wood, which develop a beautiful patina through the influence of sun, wind and rain. Or it is reminiscent of burning wood, with its flickering play of yellow and red colours.
