When M-Projects purchased 1864 Greenwich St. in 2012, it was a modest two-bedroom with some quirky features, like a stove in the dining room. M-Projects blew out the interior and built up the property to stand four stories high with over 4,500 square feet. The home’s multi-tiered roof is topped with connected decks, the tallest of which offers panoramic views of the neighborhood and the nearby Golden Gate Bridge.

M-Projects and Larson Shores Architecture + Interiors took a “bespoke” approach to the renovation, as evidenced by the unique facade made from strips of hand-cut cedar. This motif is echoed in the interior, where vertical slats of wood frame the stairwell and define some of the interior spaces.

Skylights shower the rooms with natural light, and a sunny courtyard cuts through the second floor living space to illuminate the interior like a lantern. Natural materials and finishes reign throughout, and the designers lowered the home’s energy footprint by installing energy-efficient appliances, LED lighting, and a radiant heating system controlled by Nest smart thermostats.

The home is currently on the market, although interested buyers will have to dig deep. Its asking price is $6.99 million – steep even by San Francisco standards.
