This birdhouse-shaped treehouse designed by Nendo houses two birds with one stone.

Designed for the Momofuku Ando Center, a facility devoted to promoting and increasing access to nature activities, this bird apartment houses a person and also acts as collective housing for birds. One one side, the treehouse has 78 nest spaces for birds to make their home and one the other side, there is one entrance for a human. Just pop this birds nest bed inside and your aviary apartment is complete!
