We're not sure if it's the biggest house in the US. But it is the most expensive. This Bel Air Mansion with Car Collection is a brand-new, over-the-top build that includes absolutely everything. "Everything" encompassing more than just the four floors, 12 bedrooms, 21 bathrooms, three kitchens, massive home theater, and infinity pool with swim-up bar. It includes all the furniture, all the gadgets, all the wine, all the candy, the custom-built glass ping pong and billiards tables, shoes and balls for the bowling alley, and the helicopter. It even includes a $30 million car collection that features a custom Rolls-Royce and a Bugatti. And to help you take care of it all, it comes with seven full-time employees who live in their own "staff wing", ensuring that once you move in you won't need to lift a finger unless you want to.
Rising up behind a 19th-century stable wall, the Kew House does a standout job of joining the old with the new. The home is comprised of two prefabricated volumes that are joined by glass-enclosed stairways and platforms. Weathered steel cladding helps tie the exteriors in with the existing brick structures, while the bright interior is dominated by light-colored wood flooring, white walls, and oak cabinetry. The layout helps form a private rear courtyard, and keeps separate the social areas from the more private bedrooms.
