OneOneFive Hamilton Hill has achieved UDIA’s EnviroDevelopment Excellence certification for its ambition and achievement across a range of sustainability initiatives. The gas-free and environmentally sensitive development also minimises waste and reduces water and energy consumption, while retaining the site’s landform, mature trees and biodiversity. Climate-responsive planning mitigates and monitors urban heat through careful material selection, shading, and water sensitive urban design initiatives designed to hydrate and cool the landscape. The development includes two hectares of high quality, inclusive public open space that is connected via retained trees, and features nature play areas, kick-about space, remnant bushland, and waterwise landscaping. A 30% tree canopy target supports shaded, walkable streets and cooler neighbourhoods. The project honours the site’s educational and Indigenous heritage through interpretive design, material reuse, street naming, and public art. Community engagement and connection with surrounding residents has also shaped project delivery, including a pocket park co-design process and a waterwise verge upgrade initiative.
OneOneFive focuses on industry advancement by demonstrating best practice resource recovery, climate resilient and water sensitive urban design, and built form outcomes. The built form responds to physical site requirements, experiments with compact lots, and promotes timber framed construction. Design Guidelines and a Waterwise Incentive Package support residents and their builders to exceed minimum regulatory sustainability standards.
OneOneFive also serves as a living laboratory for applied research to verify sustainable design. The Waterwise Exemplar project trials waterwise initiatives, documents implementation, monitors household water use and via sensors and data visualisation and communicates learnings via presentations and site tours to assist with mainstreaming. The Smart Neighbourhood Waterwise Performance Monitoring and Evaluation project includes microclimate monitoring and modelling to understand how specific materials, vegetation, density and urban layout impact urban heat. OneOneFive is also the subject for research into circular economy construction practices.
Insights from these initiatives are informing future sustainable infill developments across Perth, advancing the city’s transition toward a cooler, more resource-efficient, and resilient urban future.
