Mattot House, Modernist townhouse on Frans Dewandre Boulevard, Charleroi, Belgium

Mattot House is a three-level modernist townhouse on Frans Dewandre Boulevard, its first two levels clad in Guérin sandstone brick in a pierre de France tone. The ground floor holds the doctor's practice, with a gently curved glass roof over the entrance; the first floor is one open space with a glazed rotunda and a balcony whose metal railing resembles a ship's rail. The top floor has two quadrangular windows echoing the neighbouring Moreau building.

Marcel Leborgne designed the house in 1937 for Henri Mattot, a gynecologist and medical director of the nearby Reine Astrid Maternity Hospital, during the urbanization of Boulevard Dewandre. In 1955 a change of ownership brought an enlargement of the second floor and a new terrace, and the tile frieze at the top was removed. Later alterations adapted the rear to office use; by 2015 an architecture firm occupied it.

The ground-floor consultation room was laid out as an office, an examination room and a dressing room, following modernist practice, while the stairwell's curves and lines belong to Art Deco. Bâtir magazine recorded the lost polychromy: blue and gold leaf, red, Macassar ebony, pale apricot, green and black. Leborgne designed all the furniture, made by De Coene frères of Kortrijk, to guarantee order and prevent unnecessary variations.

The building is best viewed from the street to appreciate its sandstone facade and staggered design. Visit during daylight hours to see the brick details and facade composition clearly.

The second floor features sliding partitions inspired by Frank Lloyd Wright, allowing flexible reconfiguration of the living space. This design made it possible to adapt the layout to different needs over time.
