I have recently been working on some new printable card buildings suitable for modern wargames such as Fireteam:Modern.
This allows a multi-storey apartment block with balconies to be constructed. The design is modular so any number of floors can be stacked on top of one another.
This PDF file includes a simple concrete government building, modular concrete perimeter walls and a gate guard box.
My previous card buildings are also still available…
A Mosque built using the “Large Building 2” Pdf and some walls. The Minaret is made out of a type of card with a toy salt shaker on top for the dome/spire.
