Haus I

Sieckmann Walther Architekten as Architects

The challenge for House I was to design a building with two equivalent residential units on the long property. Due to the narrow building site could not arise a duplex with adjoining apartments. The two units were therefore arranged one above the other in favor of an equal orientation to the garden. Due to the asymmetrically arranged pitched roof, a fully-fledged window façade to the south could also be realized in the upper apartment. The staircase set in the loggia also allows direct access to the garden for the upper apartment.


The location of the property on a former brickyard site was decisive for the earth-colored plaster facade. The roof inner surfaces were clad with Heraclit plates, which provides excellent room acoustics. In combination with the visual screed and the oak wood windows, a reduced and at the same time homelike ambience emerged.


The building has a large photovoltaic system and is heated by a heat pump. It meets the requirements of the currently highest energy-efficient KfW standard and is one of the first realized KfW-40-Plus houses in Germany.
