re: Framing House with Rough Cut Lumber

The wood to frame your house is the least expensive part of the construction project. I sell building materials for a living and have seen customers try to save money by using lumber that they cut themselves. In the end the framers charge more for having to deal with the heavy, warped, out of square, rough cut stuff that there is little to no savings.
If you want to save money do it with the finish products like plumbing and lighting fixtures not on cheap lumber.
