classical empires stamp set seems like one of the most complete sets in fantasy regional.
make it even more complete by adding some under construction structures. Even some uncut stones. Maybe even a stone cutter/carver building. if you are feeling generous, half made statues from marble blocks! It's almost as if classical empires are known for their art, engineering and architecture!
Suggested stamps to have an under construction version, rated 1-5 (5 would be most cool to have):
aqueducts 5!
houses 4
amphitheatre 4
temples 5!
walls 5!
rich houses 3
statues 5!
small statues 5!
columns 5!
