Current home. Built 1940. Noticeably more solid than a family member's home built in 1976. Brothers house built 2011 isn't more solid either.
Oddly enough, very little updating to the house and my energy bills are lower than either of theirs as well.
That has a whole lot more to do with who built than when it was built.
The house we live in now I built in '08-'09. It's a heck of a lot more solid and better built house than the one we moved out of which was built back in the 20's.
