Each half of the house was planned with a large atrium in order to also provide good living space on the lower floor. The atriums were spanned with nets, which means that the wooden façade, which has been extended into the basement, remains visually perceptible.
In the aerial photo you can see the tree population and the restricted areas on the property. The house was positioned to the north and west as far as possible. Thus, well-proportioned garden areas were created for the two units, but also space for the prescribed parking spaces for bicycles and cars on the east side of the property. In addition to the existing greenery, all new plants were selected from native trees and shrubs.
The house was built in timber frame construction. The compartment insulation is made of cellulose (recycled newsprint), and glue-free wood fibreboards were used as the airtightness level. The outer finish under the façade cladding and the installation level inside were made with wood fibre insulation. Heat and service water are generated with an air-to-water heat pump with coolant that is not harmful to the climate. Only a bathroom exhaust air was installed as ventilation. Overall, the building meets the KfW 55 standard.
The three roofs not only create exciting interiors, but are also ideally designed for maximum utilisation with photovoltaics. Visually, the roof edge of the silver tin roof has already been raised for this purpose in order to integrate the PV in terms of design. For cost reasons, the execution was postponed to the coming years.
In the façade design, attention was paid to a good ratio of closed to open areas. To the terrace on the south side, there is a large sliding door for each side of the house on almost the entire width of the interior.
The façade made of black-glazed, horizontal spruce wood boards was combined with sun protection awnings in cheerful yellow. The silver downpipes visually divide the house into six parts.
