A palace fit for a billionaire!

Elon Musk has spent a whopping $70 million buying up five properties to make a massive compound in Bel Air, creating a mini Musk hamlet up in the hills of LA.

Regarding the solar panels on the sunny side of his home, he's said previously: "We need to make [solar rooftops] as appealing as electric cars have become. The goal is to have solar roofs that look better than a normal roof, generate electricity, last longer, have better insulation, and actually have a total cost that is less than the price of a normal roof plus electricity. Why would you buy anything else?" Well the genius engineer didn't stop there, now his company has created glass solar roof TILES which are beautiful and completely awesome and we imagine he's installed these on his house by now (our pix are a few years old).

One of the homes he bought down the street is smaller, and he converted it into a ultra exclusive private school for his kids and some of his Space X employees, reports claim. The main house boasts 7 bedrooms and 4.5 bathrooms, as well a gym, a two story library, and an 1,000 bottle wine cellar.

His secret girlfriend Amber Heard is reportedly set to move in, too! We're not saying she's a gold digger, but watch out, Elon!
