I'm remodleing an old chicken coop thats 17X14, it has 8' walls with open rafters, at the peek it must be 20' with a steep roof pitch. This building was built in the early 1900's so she leans a little but really sound . I have a large Bufflo forge with a super sucker box on it and 6" stove pipe going streight up 20", 4' past the peek of the roof. I have a 238 lb Peter Wright anvil one step from the forge, 3 post vices on the oppiset wall mounted in line so I can clamp a long piece in all at the same time if needed, and 2 post drills on the wall behind my work station. the anvil is in the center of the room pretty much. And I have a 8' door that slides sidways I configured with garage doorr tract and support casters for easy opening. with out the big door it would be too hot in there. I have a class 5 gravel floor so house keeping is no problem, no sweepe, LOL. I still want to put a overhead hoist trolly system in for the heavy stuff. But I think its great. I'm in Wisconsin so the winters get pretty chilly here, thinking about putting a small pot belly stove in somewhere. search for shop layouts and with the equipment you have you'll be able to see how much room u need. Cozzy is better, I'm old school, don't have electricty Dave.
