At Warfare 2024 I bought a number of Warbases' World War 2 buildings. One of them was the small concrete shed. The plan was to use them for Modern and When Nightmares Come games.
Something in the shed is attracting the attention of some vermin.By design, the roof appears just to rest on the top of the building. Unlike many of Warbases' buildings, the floor does not have a step, it rests within the building (which lead to a mistake in construction). This, and my idea to place the building on a scenic base gave me the idea that I could use the "floor" as a plug within the building to hold the roof securely. So it was glued centrally to the roof piece.
The door and window are still to be decided
