Step 1 of 8: Approval type
The typical price range for adding extra space to a house on the ground floor is around $1,800 to $3,700 per square meter. So, for a 40 square meter extension, the cost would be between $72,000 and $148,000. If you're considering adding another floor to your house, it generally costs around 50% more than a ground floor extension.
