I Need Design Help! (please)

[Qwertz]

I have been building a series of towers in a square style. The towers will all be linked together by either portals or bridges, I have attached screenshots of the first tower (currently WIP) and would like some helpful design ideas. I don't really know what to do with the roof. Constructive criticism is fine.
(P.S Pictures in spoiler tags were not working. -.-)

Try a circular structure. That'll keep you occupied for a while.

No, really. Preferably, try setting up an enormous structure in which each layer is approximately circular made primarily of Glass (or a stained/blastproof/warded variation thereof.) Add 4 buildings to each compass point, maybe add in 4 others for a 3 buildings x 3 buildings structure. The buildings need not be identical, but they need to have 4-fold symmetry.

If that's too hard, try a mobile frame base. Careful with Iron Chests and Pipes, though, they don't work well with Frames.

How about a fully automated, Router-based, ore processing/sorting machine?

Yeah, I have done a circular structure before. Although some of your other ideas are quite cool. (I might try them)
