Tell us about yourself!
You could put boards or staple screen material up in those gaps to keep critters out. I left them open for ventilation, especially once I moved the propane meat smoker in there! :)
The roof overlaps & overhangs enough that nothing gets rained on. The siding pieces are tight enough that nothing blows in. I would say that it's not water-proof, but it is water-tight. I built in some venting at the top so the whole thing can 'breathe'. That came in real handy when I put the smoker in there last Summer!https://youtu.be/AHgSgYMSkDw
