The process of building the Sala House reflected "the client’s central role and self-empowerment, a construction deeply and fundamentally rooted to its site, structure uniquely fitted to the requirements, and a methodology never imposed from the drawing board." Discussing the Sala House in a 1986 article for Architectural Review, Doritt Fromm wrote: Design commenced with Christopher Alexander asking Andre Sala to close his eyes and describe "the most beautiful and comfortable room you can remember." The center of the home is a farmhouse-style kitchen based on Andre Sala's memory of the farmhouse that he had visited as a boy in the south of France. While the overall form of the house was planned in advance, many design decisions were made as building progressed. For example, the placement of windows and the height of ceilings was determined on site by first creating mockups in cardboard. Christopher Alexander said the mockups were considered not by a standard of "Do I like it?", but by considering "In all the variations I can think of, which is the one that makes me feel most wholesome, most whole in myself?" The house has been described as a “realisation of a working technique to install those qualities that go beyond stylistic capriciousness to comfort, simplicity and a deep sense of well-being.”
Materials
The house is noted for an unusual use of materials. With a post-and-beam structure, the exterior of the house is a one-and-one-half-inch concrete shell in striped pink and grey that echoes the colors of the eucalyptus near the home. The color was added to the concrete at the time of pouring. The concrete is not load bearing but provides a shear wall. The concrete shell also provides a substantial passive solar effect even though it is outside of a layer of Styrofoam. The interior walls, floors, and ceiling are knotty pine. The pouring of the concrete shell turned out to be surprisingly time consuming. In building the second wing of the house, a similar structure was achieved with the use of Gunite. This process was developed on another building built by Alexander in Martinez, California. The kitchen has a terrazzo floor with decorative patterns that were made with Styrofoam forms, marble dust, marble chips and cement. The colors and pattern were the result of Alexander working on his hands and knees on the site with colored pieces of construction paper. The kitchen also has a Rumford fireplace rendered in concrete, rather than brick.
Relation to ''A Pattern Language''
Alexander's 1977 book with Sara Ishikawa and Murray Silverstein, A Pattern Language, remains decades after publication one of the best-selling books on architecture; it describes a network of 253 patterns drawn from traditional construction that relate to design at every scale, including regions, cities, and neighborhoods, as well as houses, rooms, and gardens. The Sala House incorporates many of the named patterns from A Pattern Language, including:
