The single-storey house with a hipped roof from the 1950s was very solidly built: the walls are made of solid masonry and the ceilings are concrete ribbed ceilings. However, the floor plan was somewhat convoluted, as was common at the time for the desired, clearly separated rooms. The size of the flat and the room layout at the time no longer matched today's ideas of living comfort and interior design. This is why the family with five children who had purchased the house wanted to adapt the building to their needs. It was to be modernised, completely renovated, extended by one storey and brought up to the latest technical standards.

On the technical side, a mini combined heat and power plant and a photovoltaic system were installed. It generates electricity for the building and electric vehicles, as well as heat for the house, including the swimming pool. The exterior walls were insulated and covered with a uniform material. The dark façade now gives the building a calm, monolithic appearance. The use of wood gives the whole building the warm, cosy atmosphere of a residential house. This also extends to the interior of the building: oak parquet flooring, wooden window seats, a panoramic window and a long bench in the dining area create a cosy atmosphere. The staircase to the attic also becomes a piece of furniture – it also serves as a library. The upper floor now houses five children's rooms with a bathroom and a study. The attic has been converted into a new master bedroom with a dressing room, sauna and en-suite bathroom. Small changes to the floor plan and the removal of a few existing walls also resulted in fundamental spatial improvements on the ground floor: the small, separate rooms typical of the 1950s were transformed into a flowing, open-plan living, dining and cooking area where daily family life takes place. The conversion and extension have created contemporary living spaces.
