The big sets are reasonably expensive but there are smaller sets and single buildings. There is also a 6' X 4' battle mat aswell.
PMI havent seen these yet, Is it a bit like the city fight game they used to run?I think it's an updated version. I think some of the buildings have the usual "Gamesworkshop" Iconography ( 2 headed eagle emblem) but this coiuld be easily covered up. PM
