Plan for surface-level of latest dwarf fortress, with another level above for marksdwarves and over hanging walls and so on. Big open lower area is open pasture/farmland, some military stuff, etc. Enclosed areas above are roofed and second level for marksdwarves. Path to the east by eastern pillbox for siege pathing, else other openings for normal operation. Reversed left/right in actual. Military staging room next to depot, trade good storage above it.
