Attached garage plans – The attic of an existing attached garage can provide building space for a bedroom or game room. In a two-story house, you can usually access this space from an upstairs room or hallway. You will need to remove the drywall to enter this space.
Design the floor plan and electrical wiring needs of the new attic. Cut a temporary door into a room or hallway next to the garage ceiling. Alternatively, build a staircase up from a garage below. In most cases there will be no floor in place of the attached garage plans area. Run the cables between the floor joists before installing sub-floor. Install all wiring for ceiling lamp, wall plugs and sockets. Because the garage is unheated, insulate well before installing chipboard or plywood sub-floor. Frame the walls and ceiling to accommodate plasterboard. Isolate these areas with fiberglass roll-type insulation and staple in place. If the room has sloping ceilings on the sides, there should be usable attic space behind the side walls when the side walls are square. Builders refer to this attic behind a finished wall as knee room. Install a permanent doorway into a hallway or other rooms. Nail drywall in place and complete room suitable for recoating.
