A residential community located on the coast of California about 100 miles north of San Francisco was developed by Oceanic Properties, a subsidiary of the Hawaiian development company Castle and Cook, between 1962-1965, when they purchased 4000 acres of coastal timber and grazing land. They engaged San Francisco landscape architect, Lawrence Halprin, to develop a master plan of the site. Halprin’s Sea Ranch plan marks a shift away from the conventional California residential development. It reflects Halprin’s respect for the processes of nature, his appreciation for the wild beauty of the site and his commitment to the ideas of the ecological planning. Working with a planning team of foresters, geologists, engineers, architect Joseph Esherick, and the architectural firm Moore Lyndon Turnbull and Whitaker, a design evolved with clustered buildings, modern in form and massing, which were built from vernacular materials. This massing allowed for unobstructed views and large areas of open meadows throughout the site. Hedgerows, plant groupings of native species, and berms sheltered the buildings from coastal winds, and created protected areas for recreation. Condominium One, a group of 10 linked condominiums, one of the original buildings designed by Moore Lyndon Turnbull and Whitaker Architects, was listed on the National Register in 2005.
