Great-looking build, Jim! 
I use .060" sheet styrene (I buy it in 4'x8' sheets) for large structures, and also for roofs on smaller buildings. To prevent warping, I also use the same material for interior bracing, a few examples which can be seen in this thread. While I don't usually do interior details, some of these fairly recent structures were built in a manner which allows access to the interior, even if it's already installed on the layout.
