I didn't quite get just how big of a thing you were looking to build. Either large or small, if you can lay some block, it's one of the more inexpensive ways to build something these days. Lumber is just stupid expensive. Trees coming out of the woods here don't bring a lot but lumber is like gold.
Insulation isn't that difficult either, especially if it's a really small building. Small enough and a light bulb really will keep it warm in there. Just gotta make sure that light bulb isn't burned out when you need it most.
Even with a larger building, though, it's amazing how warm some of 'em will stay. I keep the cats' food and water in my garage. Nothing fancy at all. It's an ol' pig pen with "home poured concrete floors", covered nicely with a garage door and a people door and a little cheap siding. No heat. We've had nights in the single digits here this winter and the water bowl never froze at all.
Good luck with your project!
