My shop is a 11x24 portable shed. I insulated the walls and ceiling, screwed 7/16 OSB over insulation and frame, put up an interior wall and door to make a 8x11 glue up and spray finish room, put 2 bathroom vents in to pull air in thru filter box,,painted OSB with white Kilz paint, hung 6 floresent light fixtures from ceiling, put 6000 btu a/c unit in window, built 2 work benches. Put up white peg board over work Branch.. white reflects light better than plain wood...,got a yard sale dehumidifier, filled shop up with too many tools and exotic wood boards, bought an enclosed trailer for extra tool storage..
