Sea Ranch is a name with a huge aura. It is possible at once to lose and to find yourself on a path, following it past tumbledown picket fences to a driftwood throne on a secluded beach. In the early 1960s, a group of architects produced this idealistic second-home community that’s achieved cult status among architecture mavens today.

The view from inside Unit 9, Mr. Moore’s own home in Condominium One, widely considered to be one of the most influential buildings of the 1960s. He called Sea Ranch his “Mother Earth.”

Unit 9 has become a shrine for architects, whose rhapsodies fill the guest register.

Mr. Moore’s family still owns Unit 9 and has delightfully frozen it in time, down to the d√©cor.

The founding ideal, shaped by the all-star cast of architects, was that the land should be shared rather than subdivided. Left, a community garden.

Built like a barn, with plank walls and crisscrossing beams with exposed bolts, Unit-9 is poetry in wood.
