I'm watching one of those tiny house shows on tv right now, while I would not want to actually live in one (my house is small enough at 1,100 square feet) I would LOVE to have a tiny building in my backyard to use for an office. I'm almost tempted to build one. I've helped frame walls and done drywall, but there would still be a bit to learn. It would be quite a project but dang wouldn't I feel accomplished if I managed to actually do it?! I wouldn't need electricity or anything fancy, just a quiet space with a desk and chair just for ME. I wonder how hard it would be.
