Simply estimate the size of each room in your house and the number of these rooms. This gives you the total internal Gross Floor Area.

At the end it will add up the total and factor in an allowance for walls and circulation like hallways. From that, it estimates the total external area. Both numbers are needed in the Building Cost Calculator.
