This is the conversion of a building from the 1960s. The existing structure was characterized by an unattractive appearance, a very unsatisfactory entrance, convoluted vertical access, a lack of connection to the garden, nonexistent terrace areas, and completely outdated building services.

By adding a single-story south-facing extension, new terrace areas and external stairs, as well as carefully adapting the window positions and sizes, the project succeeded in completely transforming the appearance and character of the building without upending the basic structure of the house. The extension combines three functions in a single volume: on the one hand, a vestibule and cloakroom, and on the other, a dining room as an extension of the living area and a covered outdoor area. The upper part of the extension serves as a terrace in front of the master bedroom.

The basement was made usable by insulating it and adding a new floor slab (for a wine cellar, among other things), and is now accessible directly from the garden via an external staircase. The ground floor houses the kitchen, living room, dining room, music room, and a guest bedroom. The upper floor houses four bedrooms and a study.

The existing brick building was insulated with a fully thermally insulated facade. The roof was re-roofed and fitted with a PV system. The building is heated by a deep borehole and underfloor heating. The extension consists of a cross-laminated timber ceiling on steel columns with an aluminum facade.
