Bravo Zulu on the work! Much effort expended and it shows.
Some ideas for future building work (that I haven't seen anyone mention):
Stables
Dry Goods store
Auto parking garage
City Hall
Wal-Mart
Way stations (eg: small inns/post rider stations) [add to road graphic?]
Cabinet maker shop
Barrel maker shop
- That should be enough headaches for one post -
