Live out your mid-century modern fantasies in the City by the Bay.

In the early 1960s, legendary developer Joseph Eichler built about 100 houses in the Diamond Heights section of San Francisco, enlisting architect Claude Oakland to adapt the trademark sensibilities of his suburban designs for easy urban living. One of those homes was 1027 Duncan Street, now listed for sale by Corcoran Icon Properties.

When other builders rushed to meet America’s postwar population boom with copy-paste Capes, Colonials, and Raised Ranch-styles, Joe Eichler showed the Golden State a more progressive way home, democratizing mid-century modern residences in the way that Charles and Ray Eames changed furniture, Russel Wright reset the table, and Dieter Rams taught us appliances could look as good as they work.

1027 Duncan Street epitomizes why Eichler homes remain coveted today. More than an address, it’s a feeling — a timeless capsule of space-age optimism and the innately human virtues that inform objectively good design.

A born-and-bred Manhattanite with an NYU business degree, Joseph Leopold Eichler (1900-1974) first moved to the Bay Area for professional opportunities in the food business, running a poultry-and-egg concern out of the Peninsula city of Burlingame. But after renting a Frank Lloyd Wright house in Hillsborough, where Eichler lived comfortably with his family, he was inspired to hatch a new career: building modern homes that embraced Wright’s Usonian principles, and doing it at scale. By 1966, his company, Eichler Homes, Inc., had built some 11,000 houses throughout California — most in master-planned suburban tracts — along with a handful of apartment buildings and a trio of residences in New York’s Rockland County. He would come to collaborate with some of the day’s defining architectural minds, most famously A. Quincy Jones and Frederick Emmons (Jones & Emmons), Robert Anshen, and Claude Oakland.

It was Oakland who joined Eichler on the Diamond Heights project, answering an ambitious call by the San Francisco Redevelopment Agency to help transform roughly 300 acres on the eastern slope of Twin Peaks, between Noe Valley to the north and Glen Park to the south, into a modern residential neighborhood. Together, they conceived seven dynamic floor plans, ranging from about 1,600 to just over 2,000 square feet. Each design had all the Eichler signatures, including (but not limited to) post-and-beam construction, open-concept living space, radiant-heated floors, and floor-to-ceiling glass to blur the line between inside and out. There was, however, a notable differentiator: while most Eichler homes span a single floor, the Diamond Heights lot included split-level and even two-story layouts, which were better suited for the area’s hilly topography.

Sited on one of the more level lots in the area, at least by San Francisco standards, 1027 Duncan Street is one of the single-floor designs, with four bedrooms and two-and-a-half baths. The entirety of the home has been thoughtfully and thoroughly renovated, augmenting its timeless Eichler details, like paneled shoji-style closet doors, with welcome modern amenities. A gated front courtyard makes for a zen-like reveal to the front door. Once inside, you’ll be met with 1,872 square feet of airy, sun-splashed living space — not including the additional 706 covered by the landscaped outdoor spaces and the garage, the latter configured with bike racks and an EV charging port.

Clean-lined modernity and effortless warmth are evident at every turn. The kitchen boasts custom cabinetry and millwork, transitioning seamlessly to the dining area. Sliding doors allow easy egress to the front courtyard, whether you’re carrying a platter out to the grill or another round of martinis to those lounging around the built-in gas fire pit. Exposed beams and clerestory windows soar over the living room, accented with a genuine wood-burning fireplace and built-in shelving. It’s flanked by wood paneling and a wall of glass that looks out to the dreamy interior courtyard, accessible through sliders.

The sheer level of indoor-outdoor living here makes it hard to believe you’re within city limits. Beyond the duet of courtyards, there’s a turfed, custom-landscaped backyard, where a deck with built-in seating awaits for watching those classic California sunsets. Even the primary bedroom, as well as one secondary bedroom, has outdoor access, with the two remaining bedrooms peering into the central courtyard. Clever partitions, and some strategic gardening, preserve privacy while maximizing the home’s scenic location.

It’s no wonder Eichler has remained a household name for generations of Californians.

Update (3/16/26): Within days of hitting the market, and receiving 11 offers, 1027 Duncan sold for more than $1 million over asking, setting new records for Eichlers in San Francisco: highest overall sale price and highest price per square foot. Congratulations to Danny Fernandez and the Real SF Properties team at Corcoran Icon Properties on their incredible deal.
