Current deisgn for my above ground fort.
Ignore the light blue blocks, those were just measurement aids when I originally put the circular base together.
Key should be mostly obvious, but I'll state it anyways.
Black: Wall
White: Floor when inside, empty space when outside.
Light green: Door
Dark tanish color: Windows
Dark blue: Waterfall
Light/dark purple: Ramps.
The NW and SE corners will house water pump stacks that feed both the central and four outter waterfalls. Ruins the circular base, but those were the only spots I could attach a 2x4+ sized addition to the shape without making it look god awful.
Houses 24 dwarves per level. Could house more using a more standard layout, but I'm trying my hand at creating an interesting design that's also reasonably efficent instead of doing the rather drab modular designs that I've been doing.
Hmm...should modify it to see how well it'd handle nobles...
For my military:
I'll have eight of these in place on my outter wall that will house most, if not all, of my military. With four dwarves per level, two levels per structure, and eight total structures, I'll be able to maintain a standing army of 64 dwarves. I'll likely break up squads into squads of four with melee squads stationed on the bottom, crossbows up top.
