These are neat!  Though - I may keep something like this in my dining room (entrance - is an entrance to the apartment house!)

 

Thinking on something though for front porch and balcony though!

 

Balcony could be plant stuff (same for front porch!)

 

And maybe keeping kit ready for charcoal grilling together for when doing the outdoor grilling thing!

 

Maybe a lawnmower kit for easy maintenance and cleanups there! - same for weedwhacker or whatever!)

 

And maybe on the apartment door - something like a pen and paper for notes for visitors for when you're away - with directions to push info UNDER THE DOOR any messages left!
