back to estimates list. A ground level house extension in Australia costs around $1,400-1,500 per square metre. When house prices are high, as they are in many parts of Australia at the moment, adding a room or extending your living area on the ground floor can be a more affordable way to create space than moving.
Typical costs can start at around Â£8-10,000* Two storey or multi-storey extension. A multi-storey extension can, like a single storey extension, also be built to any part of the existing building. However, with an extension of more than one storey, the possibility of nuisance towards neighbours is much stronger.
