The most expensive house in America recently went on sale with a price tag of $250 million (£200m). From the outside, it could easily look like every other Bel Air mansion, but the inside tells a different story, with one huge perk worth $30 million (£24m) alone. We take a look inside.

Looking down on the building work at 924 Bel Air Road on Google Earth, you'd never believe this was the shell of the newest most expensive house in America – a $250 million (£200m) mega-mansion, nicknamed 'Billionaire', located in the heart of Bel Air, California.

This building work transformed the plot into America's most spectacular piece of real estate – an 800-square-foot mansion equipped with almost every super-rich status symbol imaginable.

The four-level house, with a 270-degree view of the Los Angeles skyline, was developed by Bruce Makowsky, who said he built it with the vision of creating the most luxurious house in America (tick), and a place where people could enjoy every element of the super-rich lifestyle in the comfort of their own home (tick again).

"I saw the opportunity because people spend so much time on their toys – planes, boats and yachts – but they live in a home 12 hours a day. Home should be the best place it can possibly be. A place you never want to leave," Makowsky told the Washington Post. And he certainly achieved that.

The mega-mansion contains two master suites, 10 over-sized VIP guest suites, 21 luxury bathrooms and three gourmet kitchens, not to mention a further 17,000 square feet of entertainment decks.

It is, of course, decorated to the highest of standards, with over 100 curated art installations like this dotted all around the house.

Inviting friends over is no problem at all. In fact, invite everybody you know to your new pad, because there's room for them all. The price of the house also includes seven members of staff, including a personal chef to help cook in the three gourmet kitchens.

The dining room features $3,500 (£2,800) Roberto Cavalli table settings and there are 450 speakers dotted around the house to pump sound through the home.

These are just some of the perks in the house, and many might not be particularly new to the typical Bel Air housebuyer. But the rest of the house is where it showcases its grandeur...

Makowsky said he wanted the buyer to feel as though they never wanted to leave, and why would they need to? The house comes with its own private cinema, big enough to seat you and all of your friends for movie night. There are over 7,000 videos downloaded and ready to play, so there's no reason not to make it a regular occasion.

Alternatively, you could opt for a game of bowling. Children and adults alike could spend many a night playing on the lanes, all while feasting on pretty much any kind of candy you fancy.

We weren't lying. The house doesn't just come with a few bags of candy, but an entire wall so you, your family or your friends can pick 'n' mix as much as you fancy.

For adults looking for a wall of slightly stronger stuff, you can head down to the wine cellar, which is fully stocked with over 2,500 bottles of the best wine the world has to offer.

And you won't find any old bottle of Champagne either. As you head into the cellar, you'll be greeted with these bottles of gold Champagne from Jay Z and Beyonce's label, Armand de Brignac, which would typically set you back $760 (£608) a bottle. And we haven't even reached the biggest perk yet.

After a night of bowling and booze, the house has plenty of opportunities for relaxing, with its own massage studio/wellness spa, including your own personal masseuse.

What LA house would be the same without its own gym? Besides, if you're forking out $250 million for a house, you probably don't want to have to buy gym membership on top.

One of the most spectacular features of the house has to be the infinity swimming pool, which is 85 feet in size and sits casually on the roof, looking down onto the skyline ahead. It comes equipped with a 18-foot-wide hydraulic television screen that rises over the pool and is worth a cool $2 million (£1.6m). Not bad.

But we now reach arguably the best part of the house: the $30 million (£24m) auto gallery that comes with 12 cars, including a limited-edition Pagani, a 1936 Mercedes 540K (worth $15 million (£12m) alone), a Bugatti, a Rolls-Royce and a Bentley, just to name a few.

And in case you actually need to do some work to help pay for this incredible lifestyle, there is of course an office for you to knuckle down.

Water features surround the rest of the house, and there's even space to park up your own helicopter. You know, just in case you ever actually want to leave.

But really, why would you? The most expensive house in America might set you back a quarter of a billion dollars, but it does come with more perks than you could dream of.
