I was driving around and came across a n'hood with pretty nice looking houses, on a hilly area. . The place in each home allotted for storing their car was shaped like a garage, was big enough for a car but not much bigger, was under the rest of the house, and had no little door and no big door. So it didn't connect to the rest of the house except by going outside.
Is there a specific name for this kind of garage?
