Concrete is so much more than just a construction material in this new home

​​​​​​​Water from a butterfly roof is channelled down rain chains at the back of this new home by Cheng Design. The water drips onto a concrete wall seeded with biomass so that it develops over time into a living green wall of moss and lichen. Also at the back of the house is the meditation room, set 45cm below grade to increase the sense of tranquil separation.
