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.
For a basic breakdown of average extension prices, follow these guidelines: From Â£1,500 per mÂ² for basic construction work, up to Â£3,000 per mÂ² for high-spec materials; If youâre adding bi-fold doors, allow Â£1,400 to Â£1,800 per metre for these; Small extensions, under 15â20 square metres, have higher costs per square metre; Clay, peat, lots of nearby trees and sloping ground will all increase foundation costs
