I was at MK today and remembered some speculation as to what was going on by Crystal palace so I took some crappy (non smart phone) pictures for you. It does look like the area will be different and it's not just a refresh. The most notable change is what appears to be a footing for a short wall and a reshaping of pathways. I don't know that the paths will be any wider than they were prior to construction but perhaps this is might help with strollers blocking the paths during high traffic.
