Pressure treated wood: I see this as an essential material in modern building. Our own house used non-pressure-treated, regular boards for the sill (the walls attach to these sill boards, which are directly on top of the poured foundation, which had moisture seeping in). We got ants and termites who loved this damp wood, and they turned it to shreds in just 40 years. Will pressure treated wood last for 1000 years? I have no idea, but regular ole' wood didn't last 50 in our case.
