The most impactful examples to me are architecture and furniture. Art deco and nuveau buildings were beautiful, even minute details were meant to be looked at. The same goes for craftsman and machine age furniture. Everything has become so minimalist and utilitarian since the eighties.
I say since the eighties because thats when the pseudo minimalist home design and plastic siding started, and all furniture became laminated particle board, and fucking everything starting turning beige and grey for “resale value”. Everything became so commercial it had no substance, and we quit making things that would become antiques because they became garbage.
Make everything utilitarian, but make it so poorly it fails at it’s own utility.
