I would love to have the space to build a large quilting room. Better yet I need a separate house, with just two rooms, one being a bathroom with sink,shower & the "throne", and the other room just as big as I can get for all of my quilting things, with lots of built in cabinets, tv,microwave, computer on one end and the rest for quilting, machines, fabric and patterns. Oh to dream a bit. Good luck. Like someone posted earlier, make it as large as you can afford, with lots of windows and lighting, and builtins to take up less floor space. Enjoy, and share photos with the process and final building.
