I may be jumping the gun a bit, but these buildings are fantastic, made exactly to spec. and their modular design makes expansion to different kinds of buildings with different effects in the game an easy matter of creating sections that can be swapped into existing buildings!
Notably since buildings suffering light damage can have their tops removed, and buildings suffering heavy damage can have one section removed to reduce them to the next size category down (small buildings can't survive heavy damage), it's a great way of tracking game states with having to write stuff down or use extra markers or damage indicators.
The following are images of a small building. Medium and large buildings can be made by adding middle sections:
