An additional story has been built on top of the north part of the house to increase the floor area. In combination with an extension at ground level the house now provides more space for the family and their guests. Its 1970s character has been further developed with the result of a triple-height staircase and a diagonal view through the house by continuing the split-level idea up to the additional second floor. The internal open space serves as a communication zone while the private/intimate spaces such as bedrooms and bathrooms are clearly separated.The shape of the existing building has been respected and transformed into a contemporary form with a folded roof structure.
The former wooden rain screen covering the first and second floors has been kept as the concept and transformed into a new design of a fully insulated wall with a black waterproofed background layer and a front layer via thin vertical timber stripes on an irregular grid. The facade has been developed by KHBT as well as produced and installed. The timber fins have been coated with a newly developed mineral-based paint by the company Keim.
