Brick, Dark Grey and White
Print in 3 parts: the main building, window frame and roof.
Do not print the entire-building, but it is provided if you wanted to create a small version eg. for an OO / HO scale model railway.
The window frame can be glued in place using gel superglue, add a piece of transparent acrylic (eg. Perspex) for the glass.
The roof can be left loose to allow access inside the building.
Paint the drainpipe with acrylic paint.
For smoke effect use a OO size smoke generator.
