Oh, yeah, I think they would look really good as porch or facade decorations. Class the place right up!

Plus, if you cut them, or some of them, you could really add a number of buildings for your swanky new neighborhood.
I didn't poke around too much, but can you get other architectural elements that would match up with those? Columns, gingerbreading, and such? Could be another way to make some fancy buildings.
