A large workshop with a very small finished space is what I'm currently planning to do, leaving enough room on the property for a future owner to add a home. I'm not sure on the final dimensions, but at least a part of the shop ceiling height will be 14 to 16 feet high to allow for a lift and a larger RV if it's in my future. I've just about talked myself out of a pole barn construction, leaning toward the tubular steel with a few upgrades in materials.
