Not to say there's nothing wrong with modern construction, but keep in mind that most roman buildings also only lasted a few decades. You only see that ones that didn't disappear.
Also, do we really want to build houses that are meant to last 2000 years? It seems expensive and very impractical when you want to tear it down to build something new.
