You are definitely from a different world than I. When the original design of the house has a single car parking space included as if it was just another large room, but with a garage door on it, it is essentially inside the house, give or take an 8 inch thick concrete block wall. However, I will concede that a floor plan that horrible can be hard to imagine. It seems akin to sleeping with the horse. Probably why the previous owner took out the garage door, blocked up the hole, and subdivided the space into 2 bedrooms.
