Above the city, nestled in the southern sunny vineyards of Vienna, sits House Rock.

On one hand, it rises like an eagle's nest from the allotment neighborhood, allowing its residents possibly one of the best views from their bathtub into the surrounding hills of the Vienna Woods, in last floor is only a shower and a bathtub situated, nothing else.

On the other hand, House Rock blends into the hillside, its street-side closure contrasting with the extroversion of the tower-like lookout and the almost complete opening towards the west-facing terrace and pool.

In the basement, in addition to the double garage, there is a technical and utility room, a Sauna with fitness area, bathroom and toilet. The entire ground floor is a space for living, cooking and eating with a set sanitary and cloakroom box.

In order to be able to create as many usable outdoor areas as possible that are not visible from the street, the desired spatial program was stacked up and the street-side facade closed except for a narrow slit under the ceiling above the ground floor. The basement is interpreted as a base, with generous glazing on the ground floor as a joint and a "floating" cuboid as the attic. The challenges lay in particular in translating the abstract nature of the stacked volumes of the preliminary design into implementation details.

The snow-white Corian facade contrasts with the surrounding allotment houses, some of which are cheerfully colorful, in a winking manner. At the same time, the smooth, white acrylic stone acts as a projection surface for the shadow play of the surrounding trees.

The client's wish for high-quality materials was met discreetly and unpretentiously. Cast and polished Danube pebble terrazzo on the first floor and in the bathroom, white Corian on the facade, real wood oak planks and an opening glass facade make House Rock a real luxury piece.



The entire area approx. 12 Meter Sky Frame glass facade opens up to the garden, actually, because the facade opens automatically here. The surfaces and materials are pure, real materials like stone, terrazzo and wood. The same applies to the upper floor with dressing room, bedroom, works and television area.
The attic was not covered with sheet metal, as is the case with most single-family houses, but also made of the facade material Corian. The Corian panels of the attics are on the edge with a groove on the underside, the facade panels have a fold. Consequently dense, precise corners are created without protrusions. All facade details correspond more to that furniture construction than building construction.
