Visitors to the stacked London’s City Farmhouse donate their excrement to power the community and provide compost for the gardens, in Catrina Stewart’s conceptual design for integrated agricultural self-sufficient communities.
The Bartlett School of Architecture graduate’s design situates the community living space above public toilets, where visitor feces and urine can be harvested. The feces and urine are metabolized in biogas plants to make compost for gardening and the methane from the process is recovered to generate electricity. The waste urine water is also used to irrigate the plants, and the colorful plants and stunning gardens will be part of what draws visitors to the community in the first place.
Taking sustainability one-step further, electric eel pets would power the community elevators, and acid batteries from fruit would power street lighting. Animals will be utilized to provide fuel for heating, rather than eating, while cows provide methane gas and fertilizer.
