When I was a lad, our garage door was hinged across the top. When you opened it, it did not use up any space inside the garage.
They don't seem to make these any more: garage doors either lift up entirely into the roof space or sit with 2/3 in and 1/3 out.
Is there a good reason why people don't top-hinge them any more? For a garage that is really a workshop it would seem ideal, leaving all the roof space for storing 'stuff'.
