Alternative garage enclosure ?

Question:I have seen houses with what looks to be sliding glass doors in place of the garage door. does any one know where to find these. there not available at lowes or home depot or anyother home improvement store. im trying to avoid framing up a wall to put doors and windows in, i dont want to deal with all the building permits and this seems like a great alternative. if anyone has any other ideas, i would greatly appreciate it. thanks
