Project size: 3,400 square feet
Program: The project is a renovation and addition to an existing single-family midcentury hillside house. The existing open plan, roof form, cantilever deck, and basic layout epitomize the beloved inside-outside living style of Californian modernism. The challenge was to take a wonderfully conceived, but poorly realized structure and make it reach its potential under technological and budgetary constraints.
Location: Los Gatos, California
Solution: The design response accentuates the openness of the façade and the continuity of surface throughout, and creates the ability to seamlessly subdivide the space with translucent screens for more gracious living. The space below the house’s cantilevering living room was re-purposed as parking, with a sliding stacking door system that moves to the side, maintaining the feeling of flight. All lighting was replaced with LEDS that are tied into a home automation control system, and new window and door systems were installed.
Construction and materials: A contemporary cast glass translucent window was added to the far end of the entry area, in dialogue with an existing one at the opposite end. The theme of transparency is also expressed in the half wall panels around the dining area, as well as the sliding frameless glass panels between the kitchen and dining areas, and the dining and family rooms. The entry area, living room, and terrace have new custom cast concrete tiles for a seamless transition to the exterior. Hot-rolled steel is used at the two existing fireplaces, and the screen between them. The steel hearth for the family room fireplace is sculpted to form steps up to the laundry and guest bedroom wing of the house, their form being purely sculptural when the hidden coplanar wood veneered door is closed. All of the cabinet wood veneer in the kitchen area and family room is made of reclaimed Eucalyptus felled at the Presidio in San Francisco.

Wood frame and structural steel.
Manufacturer of any structural components unique to this project: In the Living Room, the new window and door systems are exposed to 80 mile per hour winds with regularity. To resist these loads while minimizing the size of the structure (view obstruction) and retain a store-bought warranty, we came up with a hybrid window system. Vertical 1/2" thick x 12" deep hot rolled steel fins are sandwiched between storefront frames. A horizontal fin at 9 feet ties the vertical fins together and provides the armature for the roller shade enclosures.
