I daydream about having a room for myself in the house; but I don't think I need one detached. They are SO cute though! I would have a ball designing one. I've looked at plans for playhouses for my kids. I'd just have to make it with a ceiling tall enough for DH (who is over 6') and someday it could be a she-shed or maybe a man-cave. I think everyone needs a little space to call their own. It's good for you. (I'm saying this as the mom whose son suggested she take her lunch to her bedroom with her laptop yesterday. )
