You need a hatch outside and above the garage door to access the loft. Like in a barn's hayloft. Swing a large triangular door down so you can access the silly things like ladders that are no fun. Of course there is a ton of space on the shelf/workbench at the rear of the shed which the car pulls its front end under. Don't forget the power strips.
edit: and i applaud the community for preventing your neighbors from building up and out all around you.
