The size of the home is the largest factor in pricing a new house's construction value, according to About.com. The larger the location, the less each square foot costs, and some rooms are cheaper per square foot than other rooms.

The architecture style also greatly impacts the value of the home. Square rooms and sharp angles cost much less than unique shapes and rounded corners. Putting a domed roof on the house also saves money due to labor costs. A second story is a great way to double the size without doubling the price.
