T-B - you're right about the paint. I live in what used to be a small commercial plant nursery, and so have these huge glasshouses to play around in. Unfortunately they're bl##dy cold in winter, and super-hot in summer. But their usefulness shows when it's raining cats and dogs ...
Sure, I'd much rather have a large heated workshop/shed, but am grateful for what I have - without somewhere to work under cover, stash wood, and all the woodworking gear - I'd be completely stuffed.
