I don't know, my house was built in 1920 and it's doing fine. Upgrades have been made- heat pumps, new wiring and so forth- but the overall design of the house isn't really that different from one built today. Except that in my house, the 2x4's are actually 2 inches by 4 inches.

That doesn't mean your house would be build like it's 1920 if it were build right now.

Besides I didn't really mean "normal" houses. But rather large buildings which have complex ventilation, sunlight, climate control and sustainability requirements. There has been a lot of innovation in that space. And it shows in the office buildings that are build today.
