During 1946 and 1947, Siple designed the model home for the Tahquitz River Estates, a neighborhood development in Palm Springs, California, by real estate developer Paul Trousdale (1915-1990). Siple also designed houses in Westdale, Los Angeles, another neighborhood developed by Trousdale.

By the 1960s, Siple was the supervising architect for Trousdale Estates in Beverly Hills, California, another neighborhood developed by Trousdale, on the former Doheny Ranch on the east of Greystone Mansion. He also designed Paul Trousdale's private residence in Palm Springs, California.
