Where does T&G Flooring appear in a typical Australian home build?

T&G Flooring is usually specified during the design and inclusions stage of your build, before you sign a fixed-price contract. The exact grade, quantity and finish included at your builder's base price varies from one Australian builder to another. Check the inclusions list attached to your contract and ask your builder to point to the specific line covering T&G Flooring before signing anything.
