Hi,
I am building a house with a builder (Northwest Sydney) and they came with a $21000 variation (mostly for thermal) which includes a lot of insulation and double glazing of windows to achieve BASIX requirements. I asked them to find another way and they said the only way to bring this about $11000 is to replace double glazing with installing ceiling fans in all bedrooms and children activity area (by our own cost). Since we really hate ceiling fans, can we install used ceiling fans to get the occupancy certificate and take them afterwards? If we want to do it, what should we be aware of?
