A striking Cor-Ten steel and glass home in San Francisco's South Park neighborhood has become the latest marker of just how far the city's luxury housing frenzy has spread. Known as the Gallery House, the three-level residence at 70 South Park set a neighborhood sales record, according to seed facts reported by The San Francisco Standard, with figures placing the sale at $11.5 million — a price that also matches what the home was asking when it hit the market.

The listing itself came from a home with a story. Designed around its owners' art collection, according to Sotheby's International Realty, the Gallery House was the product of a roughly four-year collaboration with architects Luke Ogrydziak and Zoë Prillinger of OPA Architects, resulting in a home with a weblike façade of steel and floor-to-ceiling glass, plus a rooftop garden and deck linked by an elevator. Sotheby's describes the finished space as 5,580 square feet. The property came to market and was withdrawn in August 2023.

A Broader Map for Eight-Figure Homes

San Francisco has seen a new crop of neighborhoods with eight-figure home sales, broadening the geography of the city's luxury housing market.

South Park itself has lived through three distinct tech booms since the late 1990s, as the San Francisco Business Times notes, giving the neighborhood's latest record sale an extra layer of historical resonance.

Potrero Hill and Alamo Square Join the Club

South Park isn't the only unlikely neighborhood crossing the eight-figure threshold. An updated midcentury modern home in Potrero Hill sold for $10 million in September, setting a neighborhood record, according to seed reporting. In Alamo Square, a 6,000-square-foot Victorian built in 1899 at 818 Steiner sold for $10.5 million that same month — a sharp jump for a neighborhood where, just months earlier, an Alamo Square home tied to Stripe's billionaire founders sold for $9.125 million, a figure The San Francisco Standard reported as a record for that neighborhood at the time. The Collison brothers had purchased that Alamo Square home for $7.35 million back in March 2017 through two LLCs.

Agent Butch Haze listed 1125 Hayes at a teaser price of $7 million. A Mediterranean-style home elsewhere in Alamo Square sold for $9 million, $2 million over its asking price, per the same seed reporting.

The Numbers Behind the Frenzy

The citywide data backs up the anecdotes. More than 90% of San Francisco houses sold above asking price recently, with the typical sale closing 31% above the listing price, according to the San Francisco Business Times, which described the city's bidding wars as hitting a record high.

Separately, the luxury single-family market climbed 25% to 30% over a six-month stretch, according to sfstandard.com.

Competition Across the City

San Francisco's recent housing market has featured intense competition for homes.

The expansion of eight-figure sales into additional San Francisco neighborhoods points to a broader luxury housing market.
