The project proposes an inverted McMansion in an arid climate which, in its final act of over-consumption, ingests its own rear yard. However this act leads to its own survival. The ingested yard now becomes an activatedorganic machine for the harvesting and filtration of a single body of water that is perpetually recycled in a semiclosed system.The original pitched roofs made for shedding water are now opportunistically reconfigured to collect water, and harvest energy. The newly ingested yard/lawn becomes a lush living filtration system cleaning grey and black water for reuse, while offering an Eden-like garden for its inhabitants. Eden is sustained by the toilet; a site for human waste disposal becomes a site for production, providing the necessary nutrients for the maintenance of plant and animal life, which in turn clean the water.What was once the exterior of the house is now the most private area. The most private moments are experienced in what used to be outside.
