Two things: (1) Will such buildings last several centuries regardless of rising sea levels? (2) Most of those building have basement levels for utilities, car parking etc. Flooding of the basements may render the buildings unusable or they may need to install  pumps, as some buildings already have in the downtown Perth (Western Australia), that are near the Swan River.

A better question: what about flooding of Trump's properties?

You only give some examples of *iconic examples*, which makes this question quite arbitrary. Nothing stops you from Googling the name of the building in combination with the word *elevation*. This will e.g. show you that the elevation for the Opera House in Sydney is 7 meters (the links often *also* give you the height of the structure).
