The longtime Bel-Air, Calif., home of the late actress Jane Wyatt has gone on the market for just under $6 million.

Architect Paul R. Williams, whose celebrity clients included Frank Sinatra and Lucille Ball, designed the six-bedroom home in 1936. (Williams’ signed plans are included in the sale.) The house has three fireplaces, a slate roof, a wine cellar, an office and a wood-paneled media room with a wet bar. An apartment above the four-car garage has its own deck and meditation garden. Listing agent Ian L. Brooks, of Rodeo Realty Inc., says Wyatt and her husband, the late Edgar Ward, bought the property in the 1960s and raised their children there. Wyatt, who died last October at age 96, is best known for playing Margaret Anderson in the 1950s sitcom Father Knows Best and as Spock’s human mother in the original Star Trek series.
