That doesn't seem at all true. Across millennia some basic tenets have remained - sense of proportion, symmetries etc. Even in the post industrial revolution, Victorian and Edwardian eras there was a retention of much of that. Even as they were discovering new construction methods and materials. Victorians went with fussy and gothic, but even bleeding edge suspension bridges or curtain walled mills kept much of those classic curves, proportions and symmetries in the components, and in the styling. They seem easy on the human eye somehow, and manage to remain so. Even dirt cheap mass housing nods to what's around. Upto the war, as they were exploring minimalism and modernism, they still retained most of those tenets. We can look back, and whether victorian brick and steel bridge, brick 30s public building, or modernist it somehow looks right, while 99.99% of brutalist and other post war schools remain ugly as sin, and "just wrong" to nearly everyone. As they mostly did even when new. A tiny few manage to retain a little something and become the iconic examples. Every era upto the war managed to nod to what surrounded too - to leave the street or cityscape looking "right" . Not the same, not a pastiche, but with some sympathy. Even the pre-war modernists managed to usually sit well in their surroundings, whereas currently they just take a dump on the carpet. What surrounds isn't looked at, or cared about. "look at my shit, you can't miss it", shit's everywhere. That was formerly an approach reserved for the odd mausoleum, palace or monument.
