Paying tribute to its location, the Gateway is constructed from rammed earth, although it is every bit as energy efficient and cool as any modern home. Ninety percent of its construction materials were sent to be recycled and its energy is produced with an 18KW solar-energy system. As such, the LEED certified building has a net-zero impact.

Everybody knows the desert is dry, but it won’t be here. A clever rainwater harvesting system combined with an underground storage cistern will ensure that 100% of the landscaping can be done without undue stress on existing water supplies. Dual-flush toilets and waterless urinals further ensure that the Gateway’s water footprint is kept to a minimum.
