Oh yes, I’ve heard of (but haven’t experienced myself) a low quality of a “standard” us house, but personally I really value the amount of space over many things. When the covid started, we rented a shitty thin-walled summerhouse to get out of the 5M city and keep some freedom of movement. And it was so awesome I didn’t care how much firewood we burned, or how I could hear the kids through 2 walls. Because I could step out of the door and still stay within “my territory”, my place. And in most of small apartments, not just the soviet ones, you feel trapped in those 2 or 3 concrete boxes you call home.
And if you build a house for yourself, you have a chance to make use of all the modern technologies, and some things are not that much more expensive - I know because I did plan to do it, and I even have a giant excel file with calculations and choices made. Never happened because we moved to another country.
