'''Condominium 1''' was the first unit in the [Sea Ranch](/source/Sea_Ranch%2C_California) development in [Sonoma County, California](/source/Sonoma_County%2C_California). Located on a coast overlooking the [Pacific Ocean](/source/Pacific_Ocean), the complex was designed by [Charles W. Moore](/source/Charles_Moore_(architect)), [Donlyn Lyndon](/source/Donlyn_Lyndon), [William Turnbull Jr.](/source/William_Turnbull_Jr.) and [Richard Whitaker](/source/Richard_Whitaker_(architect)) of the MLTW partnership in 1963–1964, and was built by contractor Matthew Sylvia in 1965. The timber-framed structure has been described as one of the most significant architectural designs of the 1960s in [California](/source/California),[{{cite web | url={{NRHP url|id=05000731}} | title=National Register of Historic Places Registration Form: Condominium 1 | publisher=National Park Service | date=December 15, 2004 | access-date=May 6, 2012 | author=Carlson, Pamela Joan}}] and has received numerous awards.
==Description==
Condominium 1 is located on the edge of a cliff overlooking the Pacific. It is a complex of ten condominium units, intended to be seen as a single structure. The design was inspired by barns and other farm buildings in the region and, with the help of landscape architect [Lawrence Halprin](/source/Lawrence_Halprin), was built to take into account the local ecology.[{{cite book | last =Wiseman | first =Carter | title =Shaping a nation: twentieth-century American architecture and its makers | publisher =[W.

Windows are plain openings without trim or [mullions](/source/mullions). There are no eaves or significant fascia trim. On the uphill side the building wraps around a courtyard that houses the units' garages. Interior spaces feature the full range of MLTW-developed design elements.
The 10-unit structure was Moore's first major work. It exemplifies Moore's "shed style" with single-pitched roofs, board siding, and plain detailing. The style, with its emphasis on a partnership with the site, was a break from the [International Style](/source/International_Style_(architecture)). The design principles established by Condominium 1 included the use of what Moore termed [aedicules](/source/Aedicula), small intimate spaces defined by four columns and a canopy, and "saddlebags", small projections of the interior space to the exterior that provide a view or a contemplative space.[{{cite book|last=Unwin|first=Simon|title=Twenty Buildings Every Architect Should Understand|url=https://books.google.com/books?id=xbpxST0YncQC&pg=PA164|year=2010|publisher=Routledge|isbn=1-136-95505-4|page=164}}] The units are arranged with horizontal and vertical view lines through the space.
