Trees grow on top of five concrete boxes, like oversized pot plants, at this house in Ho Chi Minh City by Vietnamese studio Vo Trong Nghia Architects.
From the architect. Under rapid urbanization, cities in Vietnam have diverged far from their origins as sprawling tropical forests. In Ho Chi Minh City, for example, only 0.25% area of the entire city is covered with greenery. An over-abundance of motorbikes causes daily traffic congestion as well as serious air pollution. As a result, new generations in urban areas are losing their connection with nature.
