Often the most expensive part of the house building is the labor, and if you can do some of that yourself or work with a builder who can tell you how to save labor costs you can do quite well.

For example, a simple "shed roof" without any gables or whatever those little decorative accents you see at the corners can be much cheaper (each accent could cost $500-2000 in labor alone). If you have a builder and architect who work together, you can really reduce the cost without making the house look like a garage with windows.
