Mystical, magical, green. A house for its human occupants and a house for the trees. More importantly a house that gives to the city as well. The design for the award winning House for Trees in Ho Chi Minh City, Vietnam aims to address the overwhelming lack of vegetation in this urban centre as well as providing a connection to nature and a means to alleviate flash flooding from storm water run off. Each building is a giant planter box. Monolithic at ground level, ethereal above. By Vo Trong Nghia Architects.
