I sectioned off, and walled one corner of my basement for light woodworking and assembly and disassembly of jobs. The room is 12'x12'. It has one double window to let light in. I sealed the concrete floor, then added 1" thick rigid insulation, taped all the seams, put 3/4" T&G plywood on top, drove concrete screws through to prevent the plywood from shifting, then put 3/4" thick 3'x4' rubber mats down. If you're going to be standing all day, take care of your feet and back. The walls which share the exterior are insulated and with moisture barrier. I attached 3/4" plywood to all the walls so I can easily attach anything to them. Heavy stuff gets attached to the studs. I ran 1/2" EMT conduit on the wall surfaces with plenty of 20amp outlets. I have 6 fluorescent fixtures (12- 4' tubes). (I do a lot of small intricate operations, so I need plenty of light.) NB. I have no shag carpeting
