I like Centre Pompidou, and if it wasn't technically problematic, it could have aged really well.

For those who don't know, Centre Pompidou is built "inside out", with all the technical parts like ducts, framing, elevators, etc... fully visible from the outside. There is some beauty from function here, like looking at an old locomotive. For people in the future, it would be an insight into what a 20th century building is made of.

Problem is: for a form-from-function design it is not very functional. Because the technical parts are also part of the aesthetics, it makes maintenance problematic. Every single pipe you change has to be of the same model or you would ruin the façade, which is crazy. Unfortunately (for me), it is one of the least likely building to stand the test of time, from a technical perspective.

Other than that, the Louvres pyramid is starting to gain some acceptance, even though it was almost universally hated when it was built, who knows how it will be seen a few hundred years from now, if it still stands.
