Around here we have just white castles...never seen a white tower, but I guess that's a regional thing-
Jayjay, depending on your given footprint needs, you could easily grab some evergreen styrene sheets and make your own building using the TLR method. You can simply scan a burger box or bag for the sign{s}. Going by the above white tower pic, you could use small brass or plastic tubing to run thin wires thru for LEDs to light the outside of the building- try your hand at some thick foil from a wine bottle{better grade ones with a cork- not what I usually drink-hehehe} for the lamp shades.
Great ideas, Bob. I need to try those. As for White Tower, I never saw them around Chicago, but I was well acquainted with the two in Dayton, where I went to school many years ago. Here is the one on Fifth Street in June, 2001, when I was back in town. It figures in a couple of well known railroad photographs (that I now will have to find). ** (One is by David P. Oroszi, and appears on p. 18 in Greg McDonnell's excellent railroad photography book, "Heartland". It shows Amtrak's Capitol Limited on the viaduct, led by E-9s, on a snowy January 29, 1978.).
