I built almost the entire airframe in the same size basement of my Bi-level, it was way better than the garage. I built the wing/fuse in the basement, wings were also fully riveted but I dissassembled the fuse for deburring and reassembled and riveted the fuse in the garage.
I left the air compressor and other loud/messy tools in the garage, I made a small hole in the wall to pass the air hose and an extra extension cord into the basement. It worked great keeping the mess and noise in the garage, plus it opens up the outlets in the basement. I did have to plan air tool usage around the wife's TV shows however...
