Built on an extremely steep piece of land with an area of only 450m², Dietrich│Untertrifaller designed this single family home to best fit the constraints of the site. While a black painted concrete core ties the house to the hill and contains all service rooms, a more open wooden structure was chosen for the living area and bedrooms. The form of the home allows for the focal point of all the interior spaces to be the forests and the Rhine valley below.

At first sight the building looks like a freely shaped sculpture. But its form is the result of an economical calculation and translates the special conditions of the site into an architectural design. The narrow and extremely steep slope requires a layout of four levels: The garage at the top level, followed by the two residential floors and a tool room below. Corresponding to this horizontal layering the house also shows a vertical spatial structure with a reinforced concrete core uphill and a cantilevered timber construction downhill. Matching with this differentiation the inner surfaces show exposed concrete/Terrazzo or wood paneling/wood strip flooring.
