Architect Elizabeth Herrmann designed this 1,120-square-foot, gable-roofed cottage at the base of a bucolic hillside in Fayston, Vermont. The black-stained exterior morphs depending on the season. "It can sometimes be very like the textures and colors of its surroundings," Herrmann says. "The siding mimics tree bark and shadows, and sometimes blends into the woods. At other times, especially winter, the house really contrasts with the landscape’s snowy ground."
