The client, a family of five, wishes to adapt their home, built in the early seventies, to their present needs. They wish to gather all the bedrooms on one floor hence two further bedrooms and one additional bathroom are required.
The ground floor should offer more living room and the entrance is to be rearranged more generously.

Furthermore, the houses energetic performance should be improved by replacing the oil-fired heating with a geothermal heat pump and by adding further insulation to the roof and the facade.
Since the house is located in a rural environment, its outer shape is only allowed to be modified slightly.
