11x11 blocks seperated by 4 wide pathways.
11x11 can easily be cut into four 5x5 blocks for workshops.
Workshops always have a stairway directly below them leading to their respective stockpiles.
Farms get 11x11.
So do furniture and refuse.
As do barracks, although barracks are now getting cut about in half so they have an archery range nearby.
I try to put the munitions manufacturing (Special materials processing (Meltables)) near the barracks.
Woodworking industries go in between furniture and munitions, seeing as carpentry has bowyers.
Animal processing goes in between too as they make bags but they also make armor, but I also try to put them near the food stockpiles.
Stoneworking industries go by furniture stockpiles.
Special materials processing (Meltables) goes near barracks as I told.
Oh yeah, and I forgot plant processing.
That goes near the clothes stockpiles and the farm plots.
