Villa Sestier, Art Nouveau villa in Sauzet, France.

Villa Sestier stands at 102 route de Crest in the centre of Sauzet, Drôme provençale. The house has pale cream walls, a steep dark grey tiled roof with a dormer window and a brick chimney, and a square tower section holding a clock face. Tall windows with dark red surrounds pierce the facade, one of them arched, and a smaller cross-gabled wing with timber-framed upper panels edged in red projects forward.

Honoré Sestier commissioned the villa, and it was built from 1902 to 1906 by Nicolas Vernon, with Francisque Chaleyssin responsible for the decoration and furniture. The English-style park by landscape architect Gabriel Luizet was begun in 1900 and largely finished by 1902. The stables, the guardian's house, the kennels and the park were inscribed as monuments historiques in 2012, and the whole villa was classified in 2016.

The villa takes its name from Honoré Sestier, the client who commissioned it. Francisque Chaleyssin supplied the interior decoration and furniture, and the master house retains stained glass and period wallpapers. The property is private and opens to visitors from June to October.
