To support the back-scene, control the viewing angles and support the lighting a presentation box was required. This is constructed out of the same plywood used for the baseboards plus a few odd bits of wood found lying around the garage. It is held together by half round moudling and glued with water proof wood working adhesive. It fits snugly round the outside of the based board and is bolted to it using large bolts with glued captive nuts. This works because the design of the Billy Bookcase means that the baseboard is slightly shorter than the bookcase - see the base board post to understand why.
The images also show the platforms. These are built from a single piece of card and edged with Peco platform edging. The tops are painted with a mid grey and then weathered with pastels.
The buildings have been built over a number of earlier years and may not make it to the final version.
