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.
How much does the average new house cost in the U.S? The Census Bureau says it is about $80 per square foot (or $120,000 for a 1,500 square-foot home), but this misses some additional expenses, such as closing costs, opportunity costs (on average, housing isnât the best investment), costs to furnish the house, interest costs, property taxes, etc.
