Fast, compliant BASIX certificate prep for NSW residential projects.
A BASIX Certificate is required for most residential developments in NSW to demonstrate compliance with sustainability targets for water, energy, and thermal comfort before development approval.
The BASIX (Building Sustainability Index) Certificate is a mandatory requirement for most residential projects in New South Wales, including new houses, duplex developments, and granny flats. The BASIX system evaluates the sustainability performance of a building in three key areas: water efficiency, energy efficiency, and thermal comfort.
At EcoMax Homes, we prepare BASIX Certificates by reviewing architectural drawings and assessing the building’s environmental performance. Our goal is to ensure that the design complies with NSW sustainability regulations while keeping construction practical and cost-effective.
We work closely with architects, builders, and homeowners to identify efficient solutions that achieve compliance without unnecessary construction costs. Once the final architectural plans are received, BASIX certificates are typically prepared within 24–48 hours, allowing projects to proceed smoothly through the approval process.
