Owners or designers lodging a DA or CDC for a new dwelling, alterations and additions, or a pool, who need the BASIX certificate done quickly and correctly.
Preparation and issue of the Building Sustainability Index (BASIX) certificate you need to lodge a Development Application (DA) or Complying Development Certificate (CDC) for a new dwelling, pool or alterations over the BASIX threshold in NSW. We run the water, energy and thermal inputs from your drawings, resolve any shortfalls with practical spec changes, and issue the certificate with one revision round included.
New dwellings, pools and spas, and alterations and additions over the cost threshold all need a BASIX certificate in NSW. If your project is under the threshold we will tell you and you will not need this service.
Most shortfalls are fixed with spec changes like tapware ratings, glazing or hot water systems. We advise the cheapest workable fixes. Genuine redesign is beyond this fee and rare.
No. NatHERS is a thermal simulation that can feed the BASIX thermal section. Larger or harder projects often need it, and we offer a bundled BASIX plus Nationwide House Energy Rating Scheme (NatHERS) package at $990.
With complete drawings, typically three to five business days. Missing window schedules and specs are the usual cause of delay.
Multi-dwelling BASIX is more involved and priced separately. This fee covers a single dwelling or its alterations.
