No, I don't have anything specific in mind. Windsor Castle is just a tad too large (but wouldn't it be Great??). I need at least a front facade and one or two interior rooms (I can always redecorate a room). If I were building something like that I'd make a hollow shell for the overall building and then for the interior I'd do the main entryway (with staircase and upper floor balcony), at least one interior room with a replaceable wall for each window and door style. These can be duplicated and lined up for closeup exterior shots and interior scenes. That would keep the file size fairly small and give the user the ability to basically create their own interiors. Think Gone with the Wind. :)
