The Walthers Rolling Mill building can be built as a complete free standing structure or as a “fake front” type of structure (below).
The rolling mill can be built as a free-standing “box” then cut diagonally to produce other false front structures (below). A tower from the coke ovens has been experimentally placed between the two halves of one kit.
Here is a view from the back of both the rolling mill and the Plastruct false front building. In this application, the rolling mill was built as a longer structure to be placed against a wall.
