I’m planning to build a 16 foot x 24 foot addition (384 square feet), which will be 2 bedrooms. It’s a pretty simple addition, extending the length of my ranch house another 16 feet. There is no basement, just crawl space. I’m planning to do it myself. I’ve heard that a good rule of thumb to have a contractor in my area do everything including wiring and extending the ductwork and finishing the inside is $75 to $100 per square foot, or $29k to $38k. So based on that, without having to go through and total up the cost of the materials, how can I come up with a rough estimate of how much the materials will cost of I do it myself?

My husband and I bought his grandmother's old house. It needs a lot of work. I'm pretty young (25) and have no idea where to start. When we moved in we painted, put in new carpet and redid some ceilings. This summer we are putting on a new roof. I wish I knew of a resource or something that would let me know what order things should be done in.
