Completed in late 2004, this 2,730 square foot project on 50’ by 114’ hillside lot in Santa Monica, CA, includes a 3-bedroom and 2 1/2-bath house (1,830 SF); a 3-person professional office (250 SF); and a 1-bedroom rental unit (650 SF). The effect is one of surprising spaciousness, both inside and out. The inclusion of the rental unit brings income essential to subsidize approximately a third of the monthly mortgage payment (which admittedly was higher due to the cost of constructing the additional square footage). Through a cleverly efficient use of the sloping site, as well as by contriving to open the interior spaces to each other and to the adjacent outdoor space as much as possible, a sense of larger scale and expansive views is created that allows each of the spaces to be in actuality smaller than normal, without feeling that way. Second, spaces are doubled up in their uses wherever possible: the dining room of the home is, during weekdays, the conference area for the office; the studio and house also share a common entry (once inside, a second, pivoting door/partition differentiates, depending upon its position, those allowed through the hall to the house from those diverted to the office to the left); the residential hearth is at once a fireplace, entertainment center, and storage compartment; the master closet is essentialized to a curtain-concealed clothes rack within the master bedroom itself; an operable awning window over the rental unit's kitchen sink opens as a dormer in the house's terrace steps to serve as a children's game table, as well as offering the tenant a borrowed view of the mountains (enhancing the unit's rentability). Lastly, terraces extend off of the house at 3 levels down the hillside, allowing the accoutrements of daily life to be left outside rather than building additional square footage to accommodate them. This includes parking, which is provided for in an open gravel area at the bottom of the site rather than in a dedicated garage, and also serves as a place for washing cars and doing other home improvement-related work; a middle terrace acts as a cooking, living and dining area open directly to the kitchen, allowing the interior counterparts of those functions to be minimally-sized; and a third, upper terrace opens directly off of the 2 children's bedrooms as a play patio where their numerous toys may be casually kept, similarly allowing their own rooms to be only as large as necessary.
