Yes they stay the same size but workshops do not Main hall also changes and some other challenges.
If you thought the snails were bad....and they did manage to divide this group just as we said they would....the new thing gives 10,000 culture to the people who open up a vein...um, I mean wallet. If you want this new chapter it is going to cost ya!!! hahaha
Bobbykitty,Battle system part 2 gets released:
oh...and we need to add roads (more spaces) to the culture buildings too. If you want to look at it as you are simply adding more of those culture buildings and not replacing, well, you they take an entire expansion plus 5 spaces (for the road) per.
And a whole lot of fighting things (barracks upgrades etc), that we can't use because we are too far ahead.
Today in chat one of the FS asked about roads for culture buildings. She was told no, but when I read that this morning I remembered this post of yours. Do you know if this starts immediately or if it only becomes necessary once you hit a specific chapter?
ETA: Also, is it just buildings or also things like the Purple Blossom trees and other non-building culture items?
