Rammed earth construction is an ancient building technique that has seen a revival in recent years as people seek more local, energy-efficient and affordable materials. In addition to being sustainable, this natural building method is also frequently aesthetically stunning as Luigi Roselli's ‘Great Wall of Western Australia demonstrates. Designed to provide accommodation for seasonal workers on a cattle ranch during mustering season, these 12 zigzag homes are crafted from iron rich, sandy clay that keeps the sun out and naturally cools the interiors.
Roselli’s new homes are buried under North Western Australia’s red-hue soil. Crafted from iron-rich, red sandy clay gathered from a nearby river, they feature a thick 18-inch zigzag facade. The earth’s thermal mass helps to keep the interiors naturally cool, while saving both energy and money.
Each of the homes comes with its own terrace that makes the most out of Australia’s sunny weather, but they all share the same huge planted roof. According to the architect, these homes move ‘away from the sun-baked, thin corrugated metal shelters to naturally cooled architectural earth formations.’ And their 750-foot rammed earth facade has become the country’s longest such wall.
