The City Classics diner

I've put the sidewalk in. There's one layer of .030 styrene beneath it, and a second layer for the sidewalk. The sidewalk layer is cut out, so the building sits inside it. This eliminates "light leak" under the building and gives a more finished look. The pavement (Durhams Water Putty) will be even with the top of the lower layer of styrene, so the sidewalk will be just above that.
