4 posts, two taller on the back, then then some cross pieces to make it all solid, then put panels on all 4 sides, you have a cordless drill, right? Well, just put 4 good screws into each panel, that way, if you need to remove them, with your cordless, it would just take a minute.
The roof, same thing, hinge it, and use two screws to hold it down.
