The Bird Park apartments, created by Hiroshi Nakamura & NAP, are located in Ebisu, Tokyo where the residents can live in complete harmony. With sustainable living projects comes the question of how to build around the environment without damaging it. The architects designed these apartments around the trees—each is positioned to avoid the branches. As I would have questioned, each apartment also is positioned far enough away from the branches or the tree to prevent a collision when the trees sway. Bird houses were also attached to the siding at the top of the building.
