The vast majority of buildings do follow the same regional templates though.

The reason they’re not specifically concrete cubes is more to do with the relative unpopularity of brutalist design than it is to do with the artistic flair of architects.

In fact I’m sure most architects would love to stamp more of their creative personality into their work but they have to dial it back for cost and practicality reasons.

I understand that it’s easy as analogy but I also could compare to shopping carts around the world. When it’s a tool the design converge to something similar for the job at hand. For corporate businesses a website is a tool. I won’t expect an artist or museum website to look like a corporate one
