adding on or selling?

[Unregistered-addon]

figure 45-55 dollars a square foot for a simple addition in my part of the country. you will need to talk with contractors to get the cost in your area. cost will also vary depending on what materials are used and how much of the finish work you have done by the contractor. example, painting interior and exterior will normall add to the cost of construction, but you can save by doing the painting yourself.
