At this moment in history, building a cheaper 50-100 year house now and letting a future developer rebuild it with hopefully carbon-neutral materials might be more sustainable, assuming that building it to last now would cost more in dollars and carbon and immediate environmental impact. If we haven't figured out how to build in a more sustainable way 100 years from now, then there might not even be any developers around anyway, so it's a win-win (sort of).
