Ha House or “Stacking Green” is a small house in Saigon, Vietnam,
a chaotic city with the highest density of population in the world.
The house, designed for a thirty-years-old couple and their mother,
is a typical tube house constructed on the plot 4m wide and 20m deep.
The front and back façades 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.
To water plants and for easy maintenance, they use the automatic irrigation pipes inside the planters.
The architects named this tropical, unique and green house “Stacking Green”
because its façades filled with vigorous and vital greenery.
The green façade and roof top garden protect its inhabitants
from the direct sunlight, street noise and pollution.
