This detached garage plan can house up to 4 cars if you are willing to park 2 cars deep. The single garage door is 18' wide and 8' tall. If you don't want to park two cars bumper to bumper this design is extra deep and would offer storage or shop space towards the back. In the far left corner is a half bath with room for a storage closet. The stairs lead up to a large loft space which could be finished to fit your needs as an art studio, recreation room, guest suite or whatever else suites.
