QUBE22

Favoriten is Vienna's 10th district and an increasingly popular place to live. As part of a three story attic extension at Quellenstraße 22, the entire existing building was completely renovated and insulated. To the west of the project there is a generous green space that offers an unobstructed view. The corner building, however, only had one side facing the green space, which is why the attic extension was turned towards the park and the course of the sun. This made it possible to allow every apartment to enjoy the green view and to bring more daylight into the interior spaces. In its form, the structure picks up the neighbouring buildings and establishes a continuous line in terms of urban planning. The cubature is clad with an air-permeable grid and the apartments offer two-sided orientation, allowing cross-ventilation similar to a historical wind tower, which is very pleasant in summer. The design elements found on the facade and a lot of cooling greenery run throughout the building. Not only the attic windows were equipped with modern sun screens, but also all windows on the existing floors received a discreetly hidden external protection against the intense southwest sun. As a small detail for the residents, the desolate fire wall of a neighboring house was renovated and designed. By immensely increasing the usable floor space, it became possible to redensify within the city and deliver urgently needed living space. This project also stands out in terms of sustainability, as the core renovation and connection to the district heating network means that the building runs on ultra-low energy requirements. An additional cooling effect was achieved by greening the flat roofs. This architectural contribution to Viennese residential culture sets new standards both visually and ecologically.
