In the wake of his distressing two-picture sojourn at Columbia Pictures, Sternberg oversaw the construction of a home on his 30-acre (12-hectares) property in the San Fernando Valley north of Hollywood. Designed by architect Richard Neutra, the avant-garde structure was built to the director's specifications, featuring a faux-moat, an eight-foot (2.4 meter) exterior steel wall and bullet-proof windows. The siege-like character of this desert retreat reflected Sternberg's apprehensions regarding his professional career, as well as his mania to assert strict control over his identity.
