Maison Unal, Modernist residential structure in Chapias, France
Maison Unal is a residential structure with connected spherical sections built directly into rock formations, integrating natural elements into its concrete shell design. The home consists of several rounded rooms linked by passages, adapting to the rocky terrain while creating fluid interior spaces.
Construction of this family residence began in 1973 under architect Claude Haüsermann-Costy's direction and continued through 1990. Painter Joël Unal contributed significantly to the design and execution throughout this period.
The home demonstrates how artistic vision shaped everyday living spaces, as painter Joël Unal directly influenced its design and decoration. This vision appears in the organic forms and custom-built furniture that flows with the architecture.
The home is a private residence and requires advance permission from the owners for any visit. It received official historical monument status in 2010, reflecting its architectural importance.
The building was constructed using a specialized concrete shell technique without traditional formwork, allowing for rounded, flowing rooms. This method enabled the creation of the soft, curved forms that define the structure.
