An expanded mid-century modern that set a mark for the priciest sale in the sunny San Francisco neighborhood of Potrero Hills seven years ago could break its own record with an asking price of $10 million.
The home at 1740 20th Street was built in 1949 and underwent a major expansion and renovation that doubled the square footage and wrapped up just before it last sold for $9.5 million in 2015. Architects Serrao Design took inspiration from the original wooden louvered window slats, operated via hand crank, for the glass versions it added in several strategic locations throughout the nearly 3,000-square-foot three-bedroom, according to a write up on the home in Dwell.
The property, located near the peak of the steep southeastern neighborhood, is small compared to others that have sold recently in the city at comparable prices, but does sit on a double-size corner view lot that allows for terraced gardens and “a spa-like wellness retreat, showcasing an outdoor shower, hot tub, and recently-installed infrared sauna,” according to the listing site from agent Gregg Lynn of Sotheby’s. The sauna is located inside the two-car garage, which has EV charging stations, but the hot tub is right along the Wisconsin Street side of the property. It cannot be seen from the street thanks to an original cement-block wall from the 1949 design; mature acacia and eucalyptus trees add privacy as well.
The owners clearly value privacy since they bought the pricey pad with an LLC. The primary bedroom suite, which has a sliding wall of doors that can shut it off from the floating glass staircase, is on its own level and is also two floors away from the home’s other two bedrooms. It has two private patios, one with a gas fire pit. The main entertaining level has its own decks, balconies and patio space, as well as a wall of windows to take in the city views. The two lower-level bedrooms share one bathroom, though there is an outdoor shower by the hot tub, which is also on this garden and garage level.
Other than the sauna, it doesn’t appear that the owners have added much in the last seven years, which is perhaps why the price tag has only inched up $500,000 since its record-breaking sale. Or it could be that the neighborhood simply isn’t ready to go beyond the mark set by the same home back in 2015. The only other single-family home in the area even close to that asking is 882 Carolina, another view property that was rebuilt around the same time period, though it is slightly larger and has an extra bedroom and two more bathrooms. It is asking $4.6 million.
