Perched atop a hill on a wooded lot with lots of privacy, this house is on the outskirts of Milford, an old mill town named a top weekend destination by the New York Times. Dozens of skylights offer a flood of natural light. Passive solar design means low energy bills, cool summer days and warm winter nights. Open floorplan provides plenty of space for entertaining and plenty of flexibility for decorating. One third of the roof’s shell is skylights, intended to merge indoor-outdoor space. Built in 1976. One bedroom, one bathroom. Second-floor kitchen. Custom-designed kitchen cabinets, lighting, railings, stairs, window and wall trim. Slate floors. Cedar-paneled bathroom. Skylights need to be replaced. Some water damage from leaking.
