mines work in process, have a single garage, have painted the walls white, boarded the pitched roof above, fitted work bench along the bakc, have power and light in it.
jobs still to do,
insulate and plasterboard the ceiling, fit a loft hatch, fit tool board, lay flooring, insulate garage door. fit strip lights get more tool boxes, mount my wood lathe on my second bench, fit my bench grinder and vice, and should be good to go. oh and put some posters up.
