'America's most expensive home' is on the market for $295 million – we take a tour

'America's most expensive home' – aptly named The One is currently for sale for an estimated $295-million. The Bel Air estate is also the world's largest private residence and is described as 'the first and last of its kind' – following predictions that a home of this magnitude may never be built again. 

The property, which took eight years to complete, was originally priced at $340 million. However, it is expected to sell at auction for an estimated price of $295-million. If it reaches the asking price, the home will hold the largest price tag in U.S. history – overtaking entrepreneur Ken Griffin's $238 million Manhattan penthouse. 

But what makes this property one of the world's best homes? Here, we take a tour of the record-breaking estate. 

Floating high above SoCal in the Santa Monica Mountains, The One exhibits panoramic views that stretch beyond downtown Los Angeles to the Pacific Ocean. The home, created by architect Paul McClean and interior designer Kathryn Rotondi features a moat of water, five swimming pools, and a 10,000-square-foot sky deck. 

However, beyond its luxe exteriors, The One is a trove of decorating ideas that accentuate McClean's architectural assets. This is showcased within moments of stepping inside the home – through its entryway that features art from sculptor Mike Fields and Italian glass artist Simone Cenedese. 

Further inside the home, there is similarly a butterfly installation by Stephen Wilson and a two-story library with Italian black hand-lacquered built-ins that have reset all home library ideas. 

Alongside its artistic features, the home exhibits a monochromatic palette that runs throughout the living room, dining room, and kitchen. This scheme creates a contrast with the colors of the mountains and city that are showcased through the surrounding glass walls (which are visible around the entire property). 

While these modern living room ideas are something to behold, The One also offers an extensive collection of amenities that set the home aside. Highlights include a Dolby Digital theater, a wellness spa, and a nightclub for when night falls above the city.

'The One is simply unrivaled. This property features ultra-luxury amenities beyond any buyer's wildest dreams,' explains Rayni Williams, a co-listing agent from Williams & Williams at The Beverly Hills Estates.

'There's a reason The One is setting a new high watermark for global real estate—more flat land coupled with the biggest views, more so than any other property previously for sale in Los Angeles,' she adds.
