Located between sports fields and a large industrial area on the extreme northern outskirts, Rosa House is a three-story residential building, which the Vorarlberg architect Sebastian Brandner built for himself and his family of four in Dornbirn.
Only 5 m narrow, but 17.50 m long, the high, narrow building sets an exclamation mark in the small residential area.
On three sides, streets and property access limit the only 400 m2 plot. Despite the exposed location, Brandner decided to radically release the house, without borders by hedges or fences and with only minimal garden design.
The garage is integrated on the ground floor on the front in the east. Behind it and above it is used and worked on only 140 m2 of usable space. The level of the architect and the living and cooking area on the first-floor form an open space continuum connected by a spindle staircase. Small and private is on the top floor, which is divided into a parent and two children’s rooms as well as a bathroom.
Not only its height but also the larch wood shell, the house highlights the Gettel roof houses plastered around. Outside, open compartments from larch wood beams divide the facades. Their axis measures halves in two steps of 2.50 m on the ground floor to 62.5 cm on the top floor. The construction grid of 1.25 m can be read, especially on the rib ceilings above the lower two floors, in the building stone. Sebastian Brandner only had flat ceilings made of boarding sperm installed above the garage and on the roof of the house.
The facades consist of prefabricated, floor-high wooden panel elements, which were provided with an inner intention on the construction site and blown out with cellulose insulation. In contrast, the carrier rust of the floor ceilings was created on-site.
