A simple architectural trick is all that is needed to create high-quality apartment units within the existing masterplan: South-facing breaches transform the linear blocks prescribed by the masterplan into townhouse-like volumes: This way, all apartments and breakfast kitchens are given two exterior facades with different orientations, one of which always is south. At the same time, the building shape makes stairwell neighbors locatable: each apartment is thus assigned its unique specific place within the estate at large. Individual apartment zones are situated concentrically around the central circulation stairwells in the interior of the buildings. The compact building shape and state-of-the-art HVAC systems (residential air-conditioning and ventilation, geothermal heat pumps, solar panels) make the entire estate meet passive house standards.
