Suggestion to add rolling pull out storage for existing outdoor storage frame.
Red n green storage from already built.
The good lady wants better use of the area.
Thought I night built some rolling pull out storage.

Perhaps large crates on castors?
Easier to fill and retrieve than shelves.
Or wheels. Maybe some sort of rails/guides would help.
