through a pair of high enamelled steel offset pivot doors that open into a great public room on the interior of the building from which all functions were to be accessed. Structural expression was designed in the form of a triangulated series of poured-in-place concrete columns, ordered on a decidedly Wrightian "triagrid" plan module that hearkens back to the Usonian house studies of the late 1940s. TP The Guide to Architecture in the San Francisco Bay Area of 1975 describes it with a single line: "Little more than a concrete moon viewing platform built for the Architect himself". Subsequently, the house has undergone a significant series of renovations and additional construction that no longer hint at its minimal beginnings. A symmetrical concrete pavilion stands atop a platform-like base, on which the "body" of the house is then supported by eight poured-in-place concrete columns that extend down to the topography running continuously below the floor. Domestic "space" occupies the sandwich between the two equally disposed square concrete slabs. The perceived thinness of the planes is achieved by means of an interlocking grid of post-tensioned concrete beams set both above the roof and below the floor to ensure the provision of uniform, column free "universal space" trapped between. Vertical supports are held back from the corners, allowing the ends to be cantilevered in space. Clear spanning glass panels, fixed and movable span vertically between the slabs, sliding open to the view, the fog and the breeze while allowing movement out onto open, covered terrace areas outside the glass envelope. The house was used briefly as a set for a locally produced feature film called the Crazy Quilt in 1966, made by John Korty who, as a neighbour, watched the house being built of poured cement and was inspired to write the screenplay of a man who loses houses to fire, earthquake and termites, then builds one that cannot be destroyed. Rocker Sammy Hagar rented the house in the mid-1970s, then bought it in 1977 with an advance from his album Musical Chairs. He continues to live in it. FHA A simple slab building standing free of the ground on sculptural concrete pilotis, the building shows most clearly the experience of the architect with the Unite building type. Other than its clarity of massing and simple façade articulation, there is little to suggest that it carries any particular pedigree other than the hand
