LA VILLA SERENA, a contemporary Mediterranean in the Beverly Hills area, provides some clues as to what a buyer can expect in new construction and amenities in the $20-million-plus price range.

Secluded and at the end of a cul-de-sac, the sprawling home sits behind 10-foot-high mahogany gates on a promontory with expansive city views.

The estate, completed earlier this year, has a formal motor court and adjacent, enclosed parking for 10 cars in what is being billed as a car museum. But the buyer needs to provide the cars. Perhaps the builder had talk-show host and car collector Jay Leno in mind.

An arched, glass and wrought-iron entry door leads inside, where baronial public rooms have 24-foot-high, hand-carved ceilings and decorative tile adorns a sweeping staircase.

The gourmet kitchen has an island, limestone counters, hand-carved marble sinks and a walk-in refrigerator. There are two wine cellars.

Off the master-bedroom suite is an area for yoga, massage and working out.

About this House: It took four years to build the house, designed by Jesse Castaneda for indoor-outdoor living and entertaining.
