Christie Walk is a model ecological cohousing development in central Adelaide, Australia. It consists of 27 dwellings (including 2 straw bale houses), on a 2,000 square metres site. It was designed by local architect Paul Downton and completed in 2006. Its innovative aspects include energy and water saving measures, use of ethical finance and use of recycled non-toxic materials. The development has been included as a case study in the Australian Government’s guide to environmentally sustainable homes and inspired similar projects such as Aldinga EcoVillage and a cohousing in Canberra (source: wikipedia).
