Wood structures in Switzerland can last an extremely long time. My relatives own a farm in the Bernese Oberland and the main farmhouse/barn is made almost entirely from wood and is at least 300 years old. There is a neighbor's farm house that has wooden beams in it that, after some investigation, the owner thinks are more than 500 years old. Another family member owns a wooden home (near Mammern) that is about 150 years old.
