Chollet's atelier is covered in a moss-green wallpaper. "I kept the wooden beams here in their original dark hue, so I wanted to add something bright and fun," says the artist. The mantel holds a series of decorative objects and family pictures. Right above it, Chollet hung two of her most personal watercolors: one depicts her horse, the other shows her daughter while riding. Olivier began collecting flags when he was a child; some of them are displayed on the stairwell leading to the top of the house's tower.
