Urban development really is it's own thing dominated by transportation systems, wealth, waste management etc. The complex math is vital and independent from other human constructs. Architecture was often influenced by the tax code, climate, material property's etc so again the details really are important and separate from everything else.

Now, sure the boundarys around a field gets fuzzy and sculpture and architecture are both influenced by the human visual system so there is overlap. But, that's not a shared theme that's D.C. and Baltimore being next to each other and sharing a few suburbs at one end, but not all suburbs.
