Loma Prieta earthquake. Although that branch of the fault was inactive during the quake, the foundation and chimney were essentially unreinforced and likely would have collapsed if the earthquake had lasted longer. A major 10-year restoration was completed in April 1999, this time with seismic reinforcement. Features The house is one-story high with a central clerestory (an outside wall of a room or building that rises above an adjoining roof and contains windows) and is constructed of native redwood board and batten, common wire-cut San Jose brick, concrete and plate glass. The house clings to, and completes the hillside on which it was built as the floor and courtyard levels conform to the slope of this one and one-half acre site. The entire site includes the main house, a guesthouse, hobby shop, storage building, double carport, breezeway, and garden house with pools and water cascade. Current use After living in the house for 38 years, the Hannas gave the property to Stanford University in 1974, to house scholars in international education, instead, it housed four university provosts. It is open for tours by reservation only. It is occasionally used for university functions such as seminars and receptions. Exterior Picture Gallery Further reading "Hanna, Paul R.
