We expanded off the back of our house to add more area to our kitchen and a little bit to the family room. A hired contractor took us to rough-in, then I took over to add drywall, paint, new floors, cabinetry, and accessories. It turned out fantastic. The added space really fits our needs better. We have more room, more cabinets, and a some office space (that frees up a bedroom). Most friends cannot believe I did all the finish work.
