Plastic breaks down in tiny pieces and is almost impossible to repair when broken. It's also very difficult to reuse or recycle when you want to. If your house is still standing after a thousand years, it's also because its habitants were able to remodel it without destroying its materials. As a matter of fact, the amazing carpentry I was talking about previously is made from "fresh" oak, but a significant part of it was also taken from a previous building (church, farm, stable or monastery). It's doing just fine, apart from a few out-of-place mortises. I tried reusing plastic pipes, once, but that wasn't a great idea. It's fine for a few DIY, though. Stones, bricks, wood are great mostly because they can be reused, but also because they will continue to look great afterwards. (Note: You might argue that "your" wood is not easy to reuse as well. This happens because we put nails and screws everywhere and we prefer less-dense wood over heavier ones (pines vs oak))
