When we bought our place it came with one of those portabl e metal car ports. The former owner bought it extra tall, 12 ft center, to park his tractor under. Since the wife decided the 28x36 shop was actually a garage for her to park in, I've started to convert the carport into a blacksmith shop. It's 20 x 24 and so far I've got the sides closed in and a walk in door hung. The West end will be closed and my side draft ran through it. The East end will have 2 5' swinging doors. Working on it has been hit & miss, but hopefully it'll be done before the weather changes too much. The floor will stay gravel and dirt. Someday hope to pour a slab and instal a power hammer.
