It’s not a good idea to show this awesome treehouse to your kids unless you’re willing to endure them constantly begging you to make one just like it for them. Designed by Robert Potokar with the help of Janez Brežnik, the freestanding wooden structure is made of spruce plywood and adds a minimalistic charm to the yard where it resides. The house even features a glass wall that is a blast for little ones to peer out of.
