Entrance To Business Premises, Dublin

I have been asked to devise a scheme for the entrance to this premises in North Dublin. Here are a couple of before and after photos. The brief was to come up with something sharp and attractive but which would require minimal maintenance. The paving is Shelbourne Black Granite with a Newgrange Silver Granite Cobble border, all from Kilsaran. The trees are Prunus lusitanica, 1.2m clear stem.
