A built-in banquette—upholstered in brown felted wool by Kravet—tucks into the corner of the living room. “The banquette also serves as the ideal location for large holiday dinner overflow,” says Caulkins. “Just pull out a folding table and add lovely linens.” She added a surprise hint of chartreuse in the inset pleat of the banquette’s skirt. The brass butterfly wall art is by Paul Villinski.
