Designed by Luigi Rosselli, the Great Wall of WA is located in Western Australia, Australia. At 230 metres long, the rammed earth wall meanders along the edge of a sand dune and encloses twelve earth covered residences, created to provide short-term accommodation for a cattle station during mustering season. With their 450mm thick rammed earth facade and the sand dune to their rear and forming their roofs, the residences have the best thermal mass available, making them naturally cool in the subtropical climate. The design of the Great Wall of WA represents a new approach to remote North Western Australia architecture, moving away from the sun baked, thin corrugated metal shelters to naturally cooled architectural earth formations.
