One man in China has built a home extension unlike any other - he's made a rock covered villa on the top of a block of flats!
It's taken owner Zhang Biqing around six years to build the rocky scene around the villa that was already there.
The rocks are fake, but the trees and bushes are real.
It might look impressive, but it's caused quite a stir.
The government says Zhang didn't get permission from them to make it so it's got to be pulled down.
It's reported that some people living in the building are worried it will cause damage to the block and has made it unsafe.
But Zhang says the rocky villa has been made from light materials like plastics and not from concrete.
