I like singular tall spires, and I will be happy to draw some. I like them best when surrounded by halfling buildings to give them meaning for foot print instead of just poking phallicly up into space with all of the materials.
Wings are very useful for other reasons including that it makes the design modular so you can build it sections at a time and have some sections finished before others are started.
I have designed hospitals before and the key to the whole thing with that and wings is to separate the wings that are in the hospital via security desks and scrub rooms, so that people get washed up when they travel from wing to wing.
I have a lot of images and a lot of files and I could post them, but I do want to try to get you guys to challenge me to make new ones instead of rely on the old.
So lets hear some ideas for some buildings?
