In a space under 10 feet wide, we have a truly unusual house to show you. San Francisco’s Cole Valley neighborhood is home to a two-story contemporary home built-in 2004. Innovative steel, glass, and rich, warm woods are used in this one-bedroom, one-bath, 1,030-square-foot residence. The living room features high ceilings and big windows that flood the room with natural light; floor-to-ceiling bookcases; richly crafted wood paneling; and a bespoke built-in sofa. The dining and kitchen spaces open onto a covered terrace with built-in seating. The house has a serene backyard and a wine cellar/home office that can be used for both purposes. The asking price for this property is $849,999.0.
