Having gone through it myself, I can tell you that a home renovation is exciting when you're planning and when it's complete, but then there's also that whole middle part where you're dealing with contractors, subcontractors, architects, noise, and dust. Throw in a construction mistake or two, and the renovation process can go from annoying to stressful as fast as you can say, "square footage." While some construction mistakes are out of your control, as the homeowner you can do more than you probably think to avoid some major construction mistakes.
