The four-storey apartment building, which was built using solid timber construction and has a partial basement, has a total of ten residential units. As a special accent, the façade was clad with natural, untreated larch wood cladding.

Even today, solid timber construction cannot be regarded as the standard acoustic construction method. Structural engineers, timber construction companies and acousticians worked together to develop solutions based on the current state of the art in order to ensure the best possible sound insulation. The basic idea was to leave the timber surfaces visible in at least one component of the room and to avoid costly and, particularly in multi-storey timber construction, unrealistic decoupling measures between the individual components. Based on the acceptance measurements, it was proven that significantly better qualities were achieved in the area of airborne sound insulation than could have been predicted on the basis of the theoretical models.
Another special requirement of the project was the inner-city courtyard location, which is atypical for passive houses. Due to the surrounding buildings and the trees worthy of protection, solar heat gains can only be exploited to a limited extent.
