BASIX & NatHERS for Riverstone homes
Riverstone is at the centre of Blacktown’s North West Growth Area, with major new estates and new suburbs like Melonba spreading out around it. New homes, duplexes and granny flats need a BASIX certificate and a 7-star NatHERS rating in this warm western-Sydney climate.
Whether you are building a detached home, a dual occupancy or a secondary dwelling in Riverstone, you will need BASIX and NatHERS documentation for the DA or CDC. Lots here are typically compact greenfield blocks where orientation follows the subdivision, so getting the glazing and shading right early is the key to reaching 7 stars without costly upgrades.
What matters when building in Riverstone
- Controlling west-facing glazing with eaves, awnings or better glass
- Lighter roof colours to reduce summer cooling demand
- Ceiling insulation to R5.0 or better, with appropriate wall insulation
- Granny flats and duplexes assessed with the main dwelling
- Whole-of-home compliance for hot water, lighting and solar PV under NCC 2022
