Entrepreneur and business magnate Elon Musk is selling his 100-year-old mansion on the San Francisco Peninsula. Listed at $37.5 million, this is the last of his real estate portfolio to be offloaded, in a bid to fund a colony on Mars.
Home to some of the most expensive houses in San Francisco, The Peninsula separates the Bay from the Pacific. At the northern tip is the city, although among locals, The Peninsula excludes that district. At the south lies the top of Santa Clara County.
The exclusive area comprises a large chunk of Silicon Valley, as well as cities such as San Mateo, Redwood, Mountain View, and Menlo Park. The character of each varies, from slices of suburbia to rural hotspots. Architecturally, The Peninsula is rich, with Hillsborough boasting an array of styles.
The cost of living is high, with demand for real estate higher than supply – in part down to the boom of local tech companies and housing not built quickly enough to accommodate. The Peninsula town of Atherton tops the list of the Bay Area’s most expensive market, with nearby Hillsborough coming in third.
On JamesEdition, the median property price in San Francisco is about $2.7 million (or around $15,000 per square meter), with prices elevating to much higher levels in the upscale Peninsula. Take this immense $135 million historic mansion or Musk’s asset for that matter.
JamesEdition currently has around 100 homes for sale in the prestigious San Francisco Peninsula area, with only 1% modern builds. Let’s take a closer look at our homes for sale there.

1. Green Gables Estate: The most expensive house for sale in San Francisco
Far and away the priciest San Francisco Peninsula property we have listed, this 32-bedroom whopper of an estate in Woodside is an architectural masterpiece that’s listed on the National Register of Historic Places. Think vast 74-acre grounds with a tennis court, trio of pools, orchards, flower and vegetable gardens, and an impressive main property that’s been standing since 1911.
The extraordinary compound was created by Banker and philanthropist Mortimer Fleishhacker, and is still in the family today. Fleishhacker enlisted the help of Charles Sumner Greene and Henry Mather Greene for design: They conceived the primary residence, surrounded by formal gardens and natural woodlands filled with giant redwoods, spruce, Monterey pines, and eucalyptus. That’s not all: Six additional dwellings dot the sizeable plot.
Alongside these wonderful features and talking points, there are two private roads within the grounds, and wood trails winding their way through – ideal for riding, strolling, and biking. It takes two hours to wander the large acreage. There’s also an on-site reservoir serving the estate’s irrigation needs.
Should you feel the need to leave for green space, Wunderlich County Park is nearby, as are Purisima Creek Redwoods Open Space Preserve and Skeggs Point. And the beaches of Half Moon Bay are just a 25-minute drive away.
Back at the nine-bedroom main house, there’s an elegant yet homely feel. Furnishings were originally chosen by famed New York interior designer Elsie de Wolfe – some still remain today. With clients such as the Duke and Duchess of Windsor and Amy Vanderbilt, her pedigree speaks for itself.
The most expensive house in San Francisco, Green Gables estate is a five-minute drive from Michelin-starred pub The Village and the same journey time from Buck’s of Woodside, a known meeting place for tech entrepreneurs and venture capitalists. The prestigious neighborhood of Woodside is also close to Silicon Valley, a 35-minute drive from downtown, and a quarter of an hour from Palo Alto.
A longstanding gathering site for global dignitaries such as European royalty and senators, the United Nations chose Green Gables for its 20th-anniversary commemoration gala in 1965. A totally private property of this magnitude is a rare find. As a home, it’s an idyllic oasis and a unique investment.
