Planning a Dual Occupancy Development in NSW?

Whether you’re building attached townhouses, duplexes or two dwellings on a single lot, a BASIX Certificate must be obtained prior to lodging your Development Application. At Green Certify we specialise in delivering fast, accurate and council-ready certificates specifically for dual occupancy projects. Our team has extensive experience addressing the unique sustainability requirements of dual dwellings, guiding you through the process to ensure your project meets NSW Government standards for energy performance, water efficiency and thermal comfort.

Why a BASIX/NatHERS Certificate is required?

Every new residential development must comply with the Building Sustainability Index (BASIX). For dual occupancy projects, each dwelling—whether they share a mirrored layout or have individual designs—must meet water and energy savings benchmarks. Our assessments ensure that your development meets council requirements from the first submission, minimises environmental impact and fully aligns with planning and sustainability regulations for dual-occupancy builds.
