Sala House, Residential structure in Albany Hill, California, US.

The Sala House is a residential structure in Albany Hill featuring an unusual concrete shell in pink and grey tones that reflects light and the surrounding eucalyptus trees. Interior spaces are divided between parental and children's areas, accessed via wooden stairs and a bridge to the upper level.

The Sala House was built in 1983 and 1984 as the first house in the United States designed and built by architect Christopher Alexander, working with Gary Black, then both professors at the University of California, Berkeley, alongside Bob Smith, David Tuttle, Seth Wachtel and Andre and Anna Sala. It was the home of Andre and Anna Sala and their two children. A second wing was added in 1988, built with gunite after the concrete-shell technique developed on another Alexander building in Martinez, California.

The home was designed around a farmhouse-style kitchen that serves as the central gathering place, reflecting the owner's childhood memories. This kitchen zone forms the heart where daily family life unfolds.

The house is a private residence on Albany Hill, so it is not open for tours; the entrance sequence can be seen from the street, where wooden stairs descend and a small bridge leads to the second-floor door. The hillside setting means steep approach steps.

The house's concrete shell performs dual functions, acting as a shear wall for structural support while utilizing solar gain for passive heating. The interior features knotty pine throughout, giving the spaces a warm, natural appearance.
