Well, since I have a house now, there's about 40' of space on the side that is not being used. I'm thinking of putting a 20x30 shop, but I don't know if it'll be big enough. I think 8' doors would be alright, but would 20' wide be enough for two rollup doors and leave enough space on the side for tools, benches, compressors, etc.? http://www.barnplan.com/index.html This place has the plans for "novices", like me, but I'm wondering if it would be cheaper to have someone build it. I don't know a whole lot when it comes to pouring concrete, and certainly not 30x30 slabs of it. Does anyone build workshops for a living on here, or have a lot of experience building them? I don't need all the bells and whistles, just 2 rollups and a door.
