Other than the walls surrounding it yes, that is what I drew in the diagram, stacked high. Basically the diagrams were on a per floor basis, and I do realize some people have trouble visualizing stuff likes those, so I was actually about to post a picture this morning since I could get on :X
If by the walls surrounding it you mean the outside walls of the building yeah did think of that and IIRC golems can move through 1 high gaps, so when I build something like this in my world my plan is to raise it one block up off the ground and then the golem can move unhindered then perhaps I will dig down to y level 6 or so and build a gigantic tower of them (just for the fun of it) and see what the output is and it should all be able to be handled by one golem (though if that seems to have trouble I may have to add floors and then make more golems.
