The volumes of the hillside house are directly related to the special topography of this area called "Donauleiten". Inclining and falling lines are characteristic of the Danube valley with its steep slopes towards the river. The south oriented glass facade maximizes solar gains during the cold seasons whereas the roof overhang generates enough shade during summer. The main facilities are located in the upper floors (street level) with a full overview towards the river from the hanging balcony. Bedroom, nursery and so on were placed in the cooler gardenfloor.
