This is coming on fast

I can't see how big/small each of the buildings are on this version because there's no grid. By my own reckoning on my own maps I've considered that a typical garden shed would be about 10' x 5', and be two grid squares long, by one grid square wide. That would be the tiniest building, I guess.

Have a close look at some of John's earlier WIPs of his first district where he still has the grid visible in the background. That might help give you some idea of a relative scale
