Regular doors are boring. This is a pocket door based off of barn door hardware. Due to the capacity of the hardware, its possible to build shelves into the design. There are some awesome hidden doors that when trimmed out are impossible to detect.... this isn't one of them. It's in a workshop in an out building, so... fine woodworking would be a little out of place.... The secret here is that most people will see the shelf and not a door.
I didn't plan on an instructable, so I didn't always take perfect photos during construction, but I will try to explain the best I can. I built what fits for my application, for that reason, I omitted exact measurements. The paneling was used due to it's light weight for the door, and I had a boatload to use up and can be seen in my Landspeeder instructable.
The door opening ended up being 81" tall by 56" wide.
The shelf depth is 11.5", and the capacity of the door 450lbs... which should be more than enough for most projects I imagine..
since this was originally posted, I also incorporated a wooden lock into the design.
