Villa Demoiselle, Art Nouveau residence in central Reims, France.

Villa Demoiselle is a large house of cream-coloured brick on a rough stone base, built on a concrete structure with a partly metal roof frame. Its dark grey roof has steep slopes, dormers, two corner towers with pointed turrets and a slender central spire. A curved pale green wooden balcony and veranda with slender columns sits at the right corner, and a banner reading "VILLA DEMOISELLE" crosses the facade above the ground floor.

Construction of this residence began in 1904 under architect Louis Sorel, commissioned by Henry Vasnier as a private home. The location across from the Pommery estate reflected the owner's position in Reims society at that time.

The name Villa Demoiselle, adopted in 2008, refers to the dragonfly (demoiselle), a muse of Art Nouveau and of René Lalique, whose opaline globes are placed around the site. The interior was redone in the original Art Nouveau style, with stencil paintings that took two years and 22,000 gold leaves. The Reims Museum of Fine Arts lends works that rotate between the museum and the villa.

The villa stands at 56 boulevard Henri-Vasnier, opposite the Pommery estate on the Saint-Nicaise hill. It has been open as a museum since its 2008 reopening, and the upper floors remain private. The cellars, restored in 2009, hold a wine library.

The house blends Art Nouveau and Art Deco styles through work by different artists, including a mahogany bar designed by Louis Majorelle and a fireplace created by Paul-Alexandre Dumas. These individual pieces show how multiple craftspeople contributed to one private home.
