The palatial SoCal home of Air Lease CEO Steven Udvar-Házy is headed to the auction block—with no reserve. Although still for sale with a $160 million asking price, the Beverly Hills estate is apparently been seriously for sale by the billionaire, who put it up for sale at least three years ago, and has asked as much as $165 million for it.

The property occupies nearly ten acres in Beverly Park—a massive lot for the neighborhood—and sits on a private road. The drive is accessed through a large set of private gates, and ends in a 30-car motor court bordered by a group of venerable Canary Island palm trees.

The Mediterranean-style mansion was completed in 1998. Its interior living spaces measure about 20,000 sq. ft. It contains twenty bedrooms and 23 baths. Its architecture borrows heavily from villa design, with keystone arches, a colonnade hallway, and Italian plaster among the details. Inlaid stone and oak floors, French doors, casement windows, exposed ceilings, antique light fixtures—including many chandeliers—and around ten fireplaces in all.

Amenities in the home include a massive great room, a media room, a library, a home theater, maid’s quarters, a wine cellar, and a home theater. On the grounds are featured a cabana and guest house, as well as covered and open patio space, a pool, a tennis court, a two-level guest house, and walking trails. An adjacent lot is available.

Concierge Auctions will be selling the property—dubbed Villa Firenze—to the highest bidder next month.

Udvar-Házy’s net worth is in the neighborhood of $4 billion.
