Cliff is Aria’s first all-electric building, supporting more efficient and low-impact living. Zoned and individually metered air-conditioning, induction cooking, and instantaneous electric hot water empower residents to manage energy use with greater awareness. On the rooftop, a complete solar system offsets common-area electricity, while every car space is EV-ready for seamless future adoption. Shared Tesla vehicles, communal bicycles, and e-scooters further support reduced private car dependence and encourage connected, active movement.

Landscape is integral to Cliff’s identity. More than 130 trees and palms, over 10,000 plants, expansive green walls, and layered subtropical gardens create a thriving vertical ecosystem that fosters biodiversity and connection to place. From shaded pocket parks at ground level to sun-drenched meadows on the rooftop, residents experience nature as a continuous, immersive journey woven through daily life.

The interiors continue this dialogue of considered living, pairing tactile, natural finishes with high-performance, energy-efficient appliances chosen for longevity, quality, and low consumption.

Cliff is not a building designed to be looked at — but to be lived in. A home that feels intrinsically of Brisbane. A place where architecture, ecology, and community come meaningfully together to create spaces that are not only sustainable, but deeply human.

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.

Sustainability underpins the vision for Moonee Valley Park. Approximately half of the site is dedicated to new botanical green spaces, supporting biodiversity and enhancing wellbeing through everyday immersion in nature. The neighbourhood is designed to prioritise pedestrians, with essential amenities located within walking distance and recreational spaces integrated throughout.

Environmental performance is embedded across the precinct. Water-efficient fixtures rated up to five stars are included in all residences, while rainwater harvesting systems capture roof runoff for landscape irrigation, reducing potable water consumption. Solar panels installed on several rooftops help offset greenhouse gas emissions from common areas. Homes and communal spaces feature energy-efficient LED lighting, thermally efficient building design, and high-performance reverse-cycle heating and cooling systems to minimise energy use.

A comprehensive waste management strategy supports construction-phase sustainability, targeting the recycling of 80% of all waste generated on site.

Moonee Valley Park was first certified under EnviroDevelopment in 2019. Its continued commitment to sustainability and innovation has now been recognised through EnviroDevelopment Excellence — acknowledging the project’s leadership in delivering a greener, more resilient community.
