The layout is in multi-purpose bedroom. It measures just under 10 feet (3m) square. The U-shaped layout provides easy access into the room and access to the closet in the room. It is built on top of bookcases and other cabinets. So far, the track on the right-hand side of the layout is completed. I have started on the track in the center section and the lower level on the right hand side. The track near the top of the diagram in the center section goes down and most of it is hidden until it emerges in the darker green area on the left-hand side.
