We’ve seen our fair share of backyard retreats, but Manuel Villa’s Habitable Polyhedron shapes up to be one of the most unique dwellings we’ve come across. Designed as an escape for young families: parents and their newborn, the Habitable Polyhedron offers respite from day to day household activities in a family’s back garden in Bogota, Columbia. One windowed side of the polyhedron opens to a teak deck leading into nature; and a skylight casts natural light on a workspace and sofa inside. Once the child grows up, the space may accommodate him in the same manner as would a treehouse or playhouse.
