I've fenced in a bit of the garden that had a drop down (on top of the brick wall). The space is now enclosed on all sides and can't be seen from the house due to the new fence. I did have pots in there but I'm not really sure what to put in there now or what to do with the space. Its about 3m x 2.5m and shady. Anyone have any low cost ideas of how to use the space?
