Some homeowners dream of looking out into their backyard and someday having a underground pool installed, but this bachelor pad took it to a whole new level. When this homeowner gets the urge to take a dip in his pool, he doesn't even have to leave the house. He and his guests can go swimming, only fifteen feet to the left of the living room, by lifting a large glass wall from the ground. The most fascinating concept of this whole design is not that this pool is indoors, but the amazing fact that when you are no longer in the mood to swim, you can simply close it and use the space as a continuation of your living area. I am officially completely jealous.
