Anjelica Huston is planning to turn her Venice, Calif., house, known as “The Fortress” into a private members club, Page Six has exclusively learned. The “Addams Family” star has thrown her weight behind the proposed social club in Venice, which would be housed in the California residence her late husband, sculptor Robert Graham, built for her in 1994. Huston, along with offering the 13,775-square-foot space and 1,000-foot courtyard for $12 million, has accepted a seat on the advisory board. “I bestow my heartfelt support for Venice Social Club Holdings’ intention to create a community gathering space that honors Venice’s unique legacy at 69 Winward Ave.,” she says, according to a proposal being shopped to potential investors. Venice Social Club plans to charge $2,000 a year for membership and will include a farm-to-table restaurant, gallery, screening room and cultural programing. According to the proposal, Venice Social Club’s members’ shared interest is “gourmet bathing,” and explains “gourmet bathing activities will range from surfing, hot-spring excursions, seltzer-water tastings, and dipping in the club’s pool.” Huston’s home went on the market for $18 million in 2010 but didn’t sell. Reps for the “Smash” star didn’t get back to us.
