Maison Gaudet, Protected historical monument in Tourrettes-sur-Loup, France.

Maison Gaudet is a residential home in Tourrettes-sur-Loup with continuously curved walls and spherical rooms throughout. The structure was built entirely from concrete, with all surfaces flowing seamlessly together and no straight lines interrupting the design.

Hungarian architect Antti Lovag designed Maison Gaudet from 1968, and work began in 1967 after a long design phase. He first built a large-scale model of the house, which served as a shelter or storehouse and then as his own lodging. Construction was interrupted several times over building-permit problems and was finished only in 2008, after the whole plot was inscribed as a monument historique on 18 November 1998.

The house is also called maison du Rouréou. Its builder, the Hungarian architect Antti Lovag, first put up a large-scale model of the future house on the site; it served as a shelter or storehouse and then as his own lodging during the long conception phase.

The house stands in Tourrettes-sur-Loup, in the Alpes-Maritimes, on a plot fully covered by the 1998 monument historique inscription. The site is private and not open for tours; the building is visible from the road. Access is by the D6085 from Nice or the D2210 through the village.

Before building, Antti Lovag made a large-scale model of the future house; it served as a shelter or warehouse, then as his own lodging. The building site, begun in 1967, was halted several times over building-permit problems and only finished in 2008, ten years after the whole plot was listed as a monument historique on 18 November 1998.
