Responding to harsh climatic conditions stands a simple and compact building that uses innovative materials with good thermal properties, has effective solar control, and water collection and treatment on site; cost-effective architecture. Building elements were standardised to meet the tight budget and time constraints as well as to reduce waste during construction. The roof was prefabricated allowing large, column free ceilings and reduced construction times on site. The residence has a single heater, and does not have to rely on air conditioning for thermal comfort. The household uses rainwater only and 110,000 L tanks formed an integral part of the sustainable design.
