Alkimos Beach developers Lend Lease and LandCorp hope to make the estate the most significant coastal development north of Perth in 50 years, with the first 240ha of the 710ha landholding expected to become home to about 6000 residents.
GBCA chief executive Romilly Madew said Lend Lease had achieved many �firsts� in the sustainability space over more than a decade, but up until now these have all been in buildings and fit-outs.
�This six-star green star rating for a community project sets the bar for world leadership community development and demonstrates a long-term commitment to sustainability at scale,� she said.
GBCA assessed Alkimos Beach against best practice benchmarks for governance and innovation, design excellence, environmental sustainability, economic prosperity and liveability.
Lend Lease�s Australia property business chief executive Tarun Gupta said the six-star rating was an example of the integrated capability of the developer combined with disciplined execution.
Mr Gupta said the estate partners had achieved world leadership in environmentally sustainable planning, design and construction at a precinct scale.
�We are very proud about achieving an Australian first and on leading the market on sustainability and community development,� he said.
LandCorp chief executive Frank Marra said their key focus was growing WA in a planned and sustainable way.
�(This) project has been recognised by the nation�s authority on sustainable buildings and communities and acknowledged as a world leading development with global significance,� he said.
The developers say the project site will eventually host 3.6ha of playing fields, 6ha of conservation reserves and 41ha of dune and foreshore reserves.
They also say all homes will be within 800m of both the local centre and transport links, and no home will be more than 200m from a park, and walking and cycle paths will link the beach, the town centre and the train station, with WiFi provided in major public spaces.
�We applaud the range of initiatives from education campaigns to financial incentives to technology that will help (residents) embrace more sustainable living,� Ms Madew said.
�This community will deliver economic, social and environmental sustainability. And the industry has proof that �world leadership� benchmarks in community development are achievable.�
Solar panels and gas-boosted solar hot water systems are mandatory in the estate, with the developers providing financial incentive packages of $4500 to $6000.
Smart water initiatives include stormwater retention, bore water irrigation and water efficient appliances in each home.
