House D // 6 is a minimal residence located in North Rhine-Westphalia, Germany, designed by Aretz Dürr Architektur. The design task was to construct a low-cost and sustainable single-family dwelling in the Oberberg region, which incorporates the surrounding landscape area into the living space and creates covered outdoor spaces for the rainy summer days in the region.
In its typology, the new building follows the traditional, one-room deep longhouse. The main rooms take up the entire width and are lined up lengthwise. The ends of the house are dedicated to different functions: Living area in the south, garage and storage rooms in the north. Typical for Oberberg, a solid base, here made of concrete, lifts the living space slightly above the naturally grown slope to protect them from the weather.
The overhang of the pitched roof is designed for both summer and winter sun stands. In summer, it protects the living space and the verandas along the length from overheating. In winter, the double glazed facade enables the solar gains to enter the living space and activate the floating cement screed as a night storage. With its reduced mass, the ventilated roof cladding supports summer thermal insulation and, together with the large roof openings, provides effective night cooling.
