I'm trying to say that while uses change that building is "effort" and if you're going to do it you should do it with the assumption that it will last.
Re-purposing old buildings is very common in the UK, and whilst sometimes that might mean essentially ripping it all out and rebuilding form the inside-out that's an extreme case. When it comes to "public buildings" and "houses" that people live in mostly the changes aren't so drastic.
I'm sure that people putting up buildings in the 1600s didn't imagine they would still be in use, but the fact that they are is a good thing. What I'm really trying to say is that planning to build something with the assumption it'll be dead/useless/retired in a hundred years seems wasteful and short-sighted. Europe is used as an example of how things have turned out otherwise. Though I appreciate there aren't any skyscrapers/tower-blocks of that age in the world. Unless you think of tenement buildings from the 17/18/1900s.
