Residential compound options on L.A.'s Westside Despite the low housing inventory on the Westside and elsewhere, several options have opened up for billionaires seeking compounds. A 48-acre spread in Brentwood's upper Mandeville Canyon area came on the market this week at $40 million. A quarter-mile-long, tree-lined driveway leads into the estate, which includes a 12,000-square-foot main house, guest houses, a tennis court with a pavilion, a caretaker's unit and a maintenance building. There's a lake on the property too. John A. Woodward IV of Keller Williams in Beverly Hills and Jeffrey Hyland of Hilton & Hyland are the listing agents. A tech titan set on more living space, less acreage and an 80-foot-long disco bar might consider a group of four side-by-side homes in Hollywood Hills that can be purchased as a compound for $36 million. One house alone, priced individually at $11.9 million, has 10 bedrooms, 18 bathrooms and 16,000 square feet of living space. Plus, the 80-foot-long swimming pool has a 4-foot-high rendition of the Hollywood Sign in blue glass tile. Valerie Fitzgerald of Coldwell Banker's Beverly Hills North office has the listing. And if money really is no object, a creative buyer could amass a Westside compound from a pair of mansions that share property lines with Casey Kasem's 2.5-acre estate priced at $42 million. One, priced at $65 million, brings a Georgian Traditional-style main house and almost 2 more acres into play. A second, currently for lease at $29,500 a month, could bring another acre to the package. Why stop there? Adjacent to it is Connie Steven's 2-acre estate, priced at nearly $18 million.
