A 1,600-square-foot in-law unit in Sonoma, California, has two bedrooms and two baths for its 87-year-old resident, whose daughter lives nearby. “The layout is well-suited for older clients,” says Jared Levy of Connect:Homes. “It feels generous and open.”
The home is mostly clad in black trapezoidal-profile steel, with cedar boards lining what the owners call the “human spaces”—external passages between buildings. A solar hot water system perches on the roof.
