The list for "most expensive homes for sale in the U.S." has officially re-shuffled to include a spec house that was recently listed in the Los Angeles area of Bel Air. Bruce Makowsky, a luxury developer, listed the Bel Air home in the past week for $250 million, making it the most expensive listed home in the country, Curbed announced Monday.

Makowsky told the Guardian in an interview that his aim was to build for an unabashedly affluent buyer. “I’ve found a niche,” Makowsky told The Guardian, speaking to 924 Bel Air Road's steep selling price. “I’m trying to build houses only for billionaires.”

Makowsky sought to push a so-called wow factor on the home for the prospective buyer. More was definitely more. “I wanted to have every spectacular thing in that house, in one place. This house is the eighth wonder of the world,” the developer said.

Indeed, the 38,000-square-foot, 12-bedroom mansion includes 21 bathrooms, six bars, a bowling alley, a home theater – complete with Hermes pillows, blankets and a 4k-gold projector – a spa and even a full stocked game room with foosball tables and a wall of candy dispensers.

Makowsky’s home might be the most expensive, but other homes boast luxurious amenities with bold price tags to match. Curbed listed 25 most expensive homes for sale in the U.S. The top properties include one location in Holmby Hills in California and the Manalapan Mansion in Florida.

The Manor in Holmby Hills, which was built for television producer Aaron Spelling and wife Candy, measured in at 56,500 square feet totaled up at $200 million. The property included 14 bedrooms, 27 bathrooms and included a nightclub in the basement and a spa with an area for massages.

The Manalapan Mansion, which was listed right behind the Holmby Hills home for $195 million, featured 33 bedrooms and 47 bathrooms. The lavish, private ocean front abode also included a botanic garden, a tree house and sports complex.
