Scripts for beginners.

Could you please provide some guidance on building construction? I found a section called "Working with Cities" in Novic's manual, but it doesn't contain information on how to build specific buildings or, conversely, demolish them in a castle. I want my players to be able to determine the stage of the game, and for the very early stages, it wouldn't make sense to have too many buildings; all the magic circles would be an overkill, for example. Is it possible to selectively build a city to suit my needs using a script?
