Alte Landstrasse residential development, Kilchberg, 2007–2011

The steep topography and a unique view of Lake Zurich and the Alps characterise this property. The eastward sloping site also benefits from the adjacent plateau, which allows better sunlight from the west. These factors create the basis for a site with a high residential quality.


The general conditions of building regulations with the stipulation of view protection and maximum excavation made it impossible to fully utilise the permitted building height. The type of house developed responds to these conditions and allows the permissible building volume to be optimally exploited through an unconventional sectional solution.

Each of the four residential units benefits from this sectional situation and features exciting compositions in their spatial sequence and light distribution. The stepped building silhouette and the bronze-coloured aluminium panels of the façade help to ensure that the buildings are harmoniously embedded into their verdant surroundings.
