I can't really see us ever going back to solid-stone construction and the kind of intricate architecture we used to have in our culture.

Rooms used to be 3m tall - they've shrunk over time to 2.4m tall. New-builds have zero storage.

Just did a self build and apparently ceilings have been rising again - 9, or 10 feet (which brings you back to 3m). Lower-volume rooms do mean less volume to heat or cool though.

Well yeah if you build it bespoke you can have ceilings as high as you want. But we're talking about houses that normal people buy from developers.
