Celilo Springs is a new home built in Mount Lawley, 2.3km from the centre of Perth CBD. The house is designed into the unusual site, which has a steep slope and permanently running groundwater springs. The design uses a single self-supporting that roof throws over the main living spaces and incorporates hanging gardens and operable roof lights. The house uses passive design principles; including solar design, passive stack ventilation, and high insulation/low thermal mass strategies to achieve a carbon-negative (more energy produced than consumed) operation.

The 120sqm house is placed on a 650sqm property and gives up a large portion of the site to landscape. The garden includes 120 species endemic to Western Australia and organised into regional associations. The garden is home to 3 different species of frogs and is used by a variety of native birds.
