House for Trees, a prototypical house within a tight budget of 156,000 USD, is an effort to change this situation. The aim of the project is to bring green space back into the city, accommodating high-density dwelling with big tropical trees. Five concrete boxes are designed as “pots” to plant trees on their tops. With thick soil layer, these pots also function as storm-water basins for detention and retention, therefore contribute to reduce the risk of flooding in the city when the idea is multiplied to a large number of houses in the future.
