www.leahday.com/shed-project/ recently posted photos and discussed the storage building she had brought in, already put together. She even crawled under it and insulated the floors from the outside. Even though you may not have the money to insulate and insure climate control right now, it may be worth your time to read her blog and see how she did it and the reasons for her choices. I grew up in the AR/MS Delta and can understand the challenges you face with extreme swings in the weather. If you don't already have windows, that would be at the top of my list. Ahh, cypress vine and morning glories growing over an arbor outside the window as you sit in your special place and think about the next project...
