In reply to PaulJepson:
> Thanks! What kind of door system?
The door on mine is the end wall of the shed, bottom hinged so it becomes a ramp when open. Two mortice locks, one each side, about 2/3s of the way up the door with their keeps cut into the stud frame. To stop someone getting a pry bar to the edge of the door the door is inset so that its inside face is flush with the back face of the studding.
Since the end of the shed doesn't support the structure I've reinforced the frames with knees set into the top and bottom corners on each side. Nothing fancy just short sections of studding chopped at 45 degrees each end and screwed into the corners.
