I'd want more like 14 x 18. The 10 ft. width is much too narrow. Don't forget after you get your shelving and cabinetry in there and your long arm etc., you need "walk around" room of at least 2 ft. or you will be very cramped. Don't forget to send us pictures when you get the project all done, many of us wish we could have a separate "girl cave". :lol:
