Horatio West Court
Why it's listed
Horatio West Court is a group of four two-story houses at 140 Hollister Avenue in Santa Monica, designed by architect Irving Gill and completed in 1919. The units sit in two pairs along a central walk, joined by walled service courts, and each has two private outdoor spaces. Walls are a six-inch concrete sandwich reinforced with steel rods, which helped the court survive largely in its original form. Garages with apartments were added in 1922, and the second-floor porches were enclosed in 1923. The court is considered one of the two finest remaining examples of Gill's social housing, the other being Lewis Court in Sierra Madre. Gill sought to provide good surroundings for lower-income families, using transitional outdoor spaces, carefully lit interiors and efficient kitchens. A restoration between 1973 and 1976, carried out by owners who were architects and admirers of early California Modern design, returned the rooming houses to single-family homes without altering the plan. The court has also drawn study from architectural historians.
Significance in brief: The nomination calls it one of the two finest surviving examples of Irving Gill's social housing, alongside Lewis Court in Sierra Madre. It is also noted for a 1973-1976 restoration by a group of architects and preservation devotees, which returned the court to single-family use and advanced preservation in Southern California.
