Let’s go green! The architectural office Vo Trong Nghia Architects designed a unique sustainable house with a vertical garden as a facade in Ho Chi Minh City. The front and back of the building are made of concrete planters that can be watered through an automatic system that collects rainwater. In addition, the facade helps regulate sunlight, noise, and pollution in the city’s tropical climate. The interior is minimalist with a wide range of wood and concrete. Green is a key element both inside and outside: there are large windows that look out over the green and some parts of the house so it feels like being outside.
