The plan that is in this book leaves quite a bit to be desired. Here are two concerns. If I wanted to put in a bank of windows, would I put in an additional 4x4 girts and posts to frame them in? Would I do the same for putting in the door? The plan also suggests a loft, but does not show any floor joists for the loft. What is the best way to put in the loft floor?

Oh, and where can I get a good chisel?
