The Janus-House in Gablitz
The Vienna woods near Gablitz is a refuge for city dwellers looking for rest and recreation. In a side valley with lush vegetation, several single-family houses line up along the road until the end of its vehicle-access zone.
One of these houses was replaced in 2018 by a new building in wooden frame construction method where now a Viennese family has created their new home. The structure discreetly fits in the sequence of the surrounding buildings.
It presents its gable-end onto street with a double pitch roof and a wood facade with very slim panels, while on the garden side it shows a hipped roof and a plaster facade. This Janus-headedness continues in the interior. Each part of the house, which has a wooden facade on the outside, is covered with wood on the inside, while the plastered exterior is covered on the inside with plasterboard.
Through this choice of materials, the spatial impression expands towards the sloping garden. The wide air space of the staircase furthers this impression. The hipped roof from the garden does not make the house appear as tall as a gable roof would.
Since this Viennese family lays great importance on hospitality, the kitchen, dining room and guest rooms are available in sufficient quantities and sizes. The exterior surfaces, such as terraces and balconies give enough scope for joyful festivities.
Due to the hillside, the so-called garden floor is used for relaxation and hobby.
The building services is easily explained: Everything that is good and useful was also installed. It is a zero-energy building at least mathematically; its outer layer has a passive house quality. Heating is provided by a geothermal heat pump combined with a residential ventilation system. Due to the hot summer, the air conditioning has been co-designed and partially realized.
