Insulated concrete forms are a great thing, they go together quickly and you don't have to strip them after the pour. They have a huge R-factor. Bucky has a good link up there. I don't understand why it hasn't caught on more either. If I ever build my own house, thats going to be the way I do my basement at a minimum. It can be finished with brick or siding or whatever outside, drywall inside. Door and window placement isn't difficult, but I would imagine it's a pain to try to change later
