This unique building was designed by Vietnamese architects Vo Trong Nghia Architects. Built for a couple and one of their mothers, the building is 20m deep but just 4m wide, typical of the narrow but long ‘tube houses’ common in Vietnam. The front and back facades are entirely composed of layers of concrete planters cantilevered from two side walls. The distance between the planters and the height of the planters are adjusted according to the height of the plants, which varies from 25 cm to 40 cm.
Automatic irrigation pipes fitted inside the planters allow for easy watering and maintenance. A rooftop garden provides shelter from the noise and pollution of the streets below. Inside the house, there are few partition walls in order to maximise views of the green facades and encourage ventilation. The rooflights also allow natural light to penetrate.
