My shop was a carport under the same roof (and loft) as the garage, with a small shop within and across the back of the garage. Because of the closeness of the house and the very limited space behind the garage I couldn’t build more than about 228sq.ft. I like the small size for working as I don’t have to walk around much, but clean-up is not fun and cut offs tend to go on the floor and/or all over the counters and bench.
