Architect Donlyn Lyndon, Key Figure in Sea Ranch Development, Dies at 90

Donlyn Lyndon, an architect instrumental in creating the Sea Ranch community on California's northern coast, died on April 5, 2026, at his home in the Sea Ranch. He was 90.

Lyndon passed away almost two months after his wife of 63 years, artist Alice Wingwall, died. The couple had built a house at the Sea Ranch decorated in orange, yellow, and red — colors chosen because red was the last one Wingwall could see after going blind in her 30s due to retinitis pigmentosa.

Wingwall, originally Alice Atkinson, met Lyndon at Berkeley, where they married in 1963; she changed her surname to Wingwall in 1980, inspired by the broken wing of a stone angel on a building in Rome.

Lyndon is survived by daughters Laura Lyndon and Audrey Lyndon, son Andrew, five grandchildren, brother Maynard, and sister Jo Lyndon. Born on January 7, 1936, in Detroit, he was the son of educator Dorothea Zentgrebe Lyndon. He earned a bachelor's degree in architecture from Princeton in 1957 and a master's in 1959.

One or two years out of architecture school, Lyndon and Princeton classmates established a weekend practice in Berkeley, California, in the early 1960s. They all held day jobs; Lyndon's was teaching architecture. , and Richard Whitaker, had been in business for only about an hour, Lyndon later joked, when they were invited to collaborate on an unusual project.

Boeke hired landscape architect Lawrence Halprin, Bay Area architect Joseph Esherick, and, at Halprin's suggestion, Lyndon and his MLTW partners. The site was a sweep of meadowland extending to bluffs along a 10-mile stretch of coastline, divided by hedgerows of half-century-old cypress trees.

Halprin proposed nestling structures against the hedgerows and leaving the meadows untouched — in developer's terms, the prime real estate. Esherick's firm designed diminutive, low-slung houses clad in redwood shingles with shed roofs, tucked into a line of cypress. MLTW's bolder assignment was a condominium building of 10 connected dwellings on a promontory with no shelter from the elements.

What MLTW created was Condominium One, a collection of small, loftlike houses made from rough-hewn redwood planks, with enormous windows framing the views and unified by a sloping shed roof to deflect the wind. It used post-and-beam construction and unpainted vertical cladding in homage to area barns. Though named Condominium One with the expectation of more structures, no others followed.

The larger development was called the Sea Ranch, conceived as a second-home community with common areas like open meadows to encourage neighbor connections. The architects' prototypes were suggestions, not prescriptions, Lyndon often said, shaped by and in deference to the wild, wind-swept landscape.

Condominium One became an icon of American architecture, as critic Paul Goldberger described it in The New York Times in 1997.

"They were more like a band than an office," Kevin Keim, director of the Charles Moore Foundation in Austin, Texas, said of the MLTW members. " Like many great bands, MLTW broke up after completing initial Sea Ranch work in 1965, not due to discord but because other opportunities beckoned.

Lyndon became a prominent academic, leading architecture departments at the University of Oregon, Massachusetts Institute of Technology, and University of California, Berkeley, finally returning to Berkeley in 1978.

He was the last living member of the Sea Ranch team: William Turnbull Jr. died in 1997, Joseph Esherick in 1998, Lawrence Halprin in 2009, Al Boeke in 2011, and Richard Whitaker in 2021. As a bearded elder, Lyndon served as a longtime steward of the ethos and ideals they set forth.

With former colleague Charles Moore and coauthor Gerald Allen, Lyndon wrote "The Place of Houses," published in 1974. The book was a plainspoken, poetic guide to thinking about making a home — the order of rooms, the placement of windows — using examples from a Japanese teahouse, Palladian villas, and the Sea Ranch itself.

It served as a gentle anti-manifesto that did not prescribe one style over another, drawing on touchstones that made people feel good.
