Warhammer Fortress Set
This set could be used in normal games of Warhammer, or in Warhammer Fortress. It is a modular set and can be combined in different ways, and extra pieces could be made to expand it later on.
It features detailed brickwork and balsa wood scaffolding, and is large enough to hold as many as 14 fully ranked units!
