Futuristic $177 Million Bel-Air Megamansion With Its Own Private Jazz Club Hits All the Right Notes at the Top of the Most Expensive Homes List

A $177 million megamansion in Los Angeles has taken the concept of world-class amenities to a whole new level, offering up an awe-inspiring array of features that only those capable of forking out such an eye-watering asking price might expect from a property.

Among the more spectacular features inside the 35,000-square-foot abode are a retractable roof in the primary suite that allows for “stargazing,” plus a sauna pod, spa, hydrotherapy chamber, and a six-car “auto gallery” that also serves as a private jazz club.

With all those impressive amenities and more, perhaps it’s no surprise that the opulent dwelling sits at the top of the week’s most expensive home listings.

Dubbed “Villa Siena,” the ultralavish spec mansion is the brainchild of Ardie Tavangarian, of Arya Group.

Other eye-popping abodes this week include a brand-new, “never lived in” penthouse in the sky in Sunny Isles Beach, FL; a Coachella Valley estate looking to make headlines again; and a Guggenheim-inspired, waterfront Miami Beach mansion.
