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.
Most builders can give you an idea of what your extension will cost per square foot or metre. For example, a basic single storey extension would typically cost around Â£1,000 per square metre but it could be up to Â£1,600 or more for a premium two storey extension.So a 3 x 5 metre extension would cost Â£15,000 and up to Â£50,000 for a two storey, more premium extension.or example, a basic single storey extension would typically cost around Â£1,000 per square metre but it could be up to Â£1,600 or more for a premium two storey extension.
