BASIX & NatHERS for Oakville homes
Oakville is a semi-rural Hawkesbury suburb where larger acreage lots are increasingly home to new builds, dual occupancies and granny flats. Each needs a BASIX certificate and a 7-star NatHERS rating, with generous blocks giving good freedom to orient for comfort.
New homes and secondary dwellings in Oakville need BASIX and NatHERS documentation for the DA or complying development certificate. The advantage of acreage blocks is freedom of orientation, so we can usually position living areas to the north and use cross-ventilation and shading to reach 7 stars comfortably in the warm western-Sydney climate.
