If you are not afraid of heights you may love this idea. For everyone else this could be a nightmare.
Two buildings currently under construction in London will have their very own pool in the sky.
Developer Ballymore is planning to build a swimming pool that will stretch between two residential buildings.
The whole thing will be made of glass and the sky pool will be 82 feet long and 9 feet deep.
Residents will also be able to swim from one building to the other.
