I wanted a building that had all my crafting benches in one area, and here is the result.

The building is 9x9, the vbuild does not contain terrain.  All 3 crafting stations are inside the building, and all 3 are fully upgraded.  The radius that it was save with was 17 units from roughly the center.  However, even with terrain you still need to clear trees, bushes, and rocks.  If you do not clear that stuff, it will still exist when you import the building.

IMPORTANT:
I highly suggest building this somewhere other than your intended spot first and get a good idea of how much room is required.  It is also helpful to backup your save file and your world file before you build this.  That way, if something is too close and gets messed up, you can revert back to before you built it.  It is also a great idea to flatten out the ground first.  I built this in a very hilly area to test.  Even with terrain, the results were not great.

One of the basic ideas behind this design was to have all the equipment served from one chest in the center.  This is possible if you use the mod Pull From Containers.  I have it listed as a requirement, but it is a soft requirement.  Meaning that to make it work as intended, you should have the mod installed, but if you don't, things will still work, but you will have to do it manually.  I also wanted there to be both light, and for you to get the Resting buff while there.  This will give you a comfort level of 4.  I also left a good amount of space for you to arrange and decorate as you like.
