We are having the concrete walkway replaced, probably with flagstone (Pennsylvania bluestone in a rectangular pattern). We'll remove the bricks and wood edging to the right of the door, and we'll have the whole yard on both sides of the walkway regraded and replanted to fill in the big open space (we took out a problematic tree and crummy brick walkway from that area).

Any thoughts on whether we need any type of edging along our walkway, or even where our little yard meets the common walkway (picture 3)? If so, what? There are lots of different things done in these yards (townhouse complex), and lots of them look terrible....

Thanks in advance!
