The single-family house is located on the southern edge of the historic village center of Auw. To the north of the building the village stream flows by, to the south of the house is the footpath to the church. The building is flanked to the east by a new building with apartments. To the west it adjoins another residential building. It has three floors and no basement. The 7.5-room single-family house was remodeled several times during its long history and had now been vacant for some time.

A total renovation with conversion work was unavoidable. The existing building structure as well as the external appearance were to be retained as far as possible.The basement and technical rooms, a workshop and a garage are located on the first floor. On the second floor, which is accessed through the arbor on the gable facade, is the actual entrance.The entrance hall, which used to be the kitchen - the former cooking area was retained and restored - functions as a distribution room. From here you can reach the representative living room with tiled stove, the new kitchen with adjacent dining room, the adjoining living room and new day toilet, as well as by means of newly installed stairs to the upper floor. Here are arranged around a hallway the bedrooms, the new bathrooms and the gable-side arbor.

The spacious attic serves as a loft.In the course of the work and detailed planning, a building archaeological investigation was carried out by the Cantonal Archaeology Aargau. This work provided valuable information for the restoration and reconstruction, which was incorporated into the rolling planning. The detailed design as well as the choice of materials and colors were carried out in close consultation with the Cantonal Preservation of Historical Monuments with the aim of uncovering as much of the building's history as possible.The external appearance could be maintained for the most part, as the building was insulated from the inside. The wooden cladding of little value on the north and south facades was replaced with a shingle facade in spruce.

The roof truss was refurbished and re-roofed with antique beaver tail tiles. Existing windows, as well as the entrance door, were professionally restored and upgraded with insulating glass. In the area of the arbors, precisely placed new glazing now provides more light in the rooms.In the interior, all surfaces worthy of preservation were expertly uncovered, restored and conservedThe lightly soaped or oiled spruce of the new fixtures, such as the new walls and doors, the bathrooms, the kitchen, the new glazing, flooring and staircase stand in tension-rich contrast to the old glass.
