Garden Storage for book exchange (Newhaven BN9)

We provide a book exhange on our driveway for the community. We had a nice cabinet, but it was destroyed in the storm. We had a second one that was stolen. We're looking for a new waterproof shed / storage locker that could go on our driveway to reinstate the book exchange and give aways. Anything similar to the photos (or another suitable option!) we'd love. It needs to be waterproof, and possible to have shelves in it. We can collect. Thanks.
