Door within a garage door?
Does anyone know of a garage door maker that offers a door within the garage door? We have a single detatched garage, and the only way in is through the garage door. I'd really like to add a standard door but, because of slopes, gardens, etc., it's not feasible to put a door on the side of the building. I know I've seen doors in garage doors before, but I think they were typically in older homes (teens/20s).
