Jared Pike Dream Pool UVs

Disclaimer: I'm not very blender experienced. And barely experienced with UVs (although I would like to be able to understand them if I can get my head around them)

So I am trying to recreate (or make my own version of) Jared Pike's "Dream Pools" artwork (just google it comes up super easily). I have managed to get a basic tile material working with some shine and some displacement. My goal is to have these tiles (all equally sized squares) on various architecture/geometry of irregular sizes and shapes with minimal seams etc. Is there a clever technique so that I don't have to painstakingly create the UVs each time? (So far I have managed to make it function on cubes of any scale using a little bit of maths).

I'm not even sure if what I'm asking is achievable but I'll appreciate any help you can get.

I don't know the best way to attach images so if you tell me how I can edit this and add them and/or anything else I'm missing.
