The house has a rainwater collection on the roof; the water is used to irrigate the plants and also feeds into the household plumbing. The rooftop reservoir helps to keep the house (which seems to be designed for a California winter) cool.
The house is also made of three floors, which means it takes up less space as populations continue to explode in the coming decades, as the press release explains:
The Incredible Edible House’s compact 30’x45’ footprint (requiring a five-foot setback) is ideal for dense urban landscapes, and its vertical format amplifies its already inherent energy-saving tendencies.
