Nice map. May I suggest improvements for the legend.
Change the background colour to white - the reason is the colours look different with a green background compared to those on the map. My eyes are er mature !. - (old).
Minor but put the legend in order of progress, so "Piling taking place" would be at the bottom below "Masts going up".
Very illuminating btw - thanks for taking the trouble to inform us.
The BIG refurbishment, however, is due to commence next year - this is when new seats, plug sockets etc. go in.
