I saw this and fell in love.
The first apartment Mr. S and I lived in was on 25th Street and 3rd Avenue in Manhattan. It was a fifth floor walkup. The only "outdoor" space we had (which is a luxury in NYC) was a little fire escape just like this shelf. Ahhhhhh memories. I don't miss the fire escape and 5th floor walkup living but I DO love this planter shelf.
