Why New American Houses Are Built to Last Only 50 Years

A 400-year-old house in Amsterdam still has people living in it. A brand-new American home is often designed to last about 50 years — roughly the length of the mortgage. That's not an accident. It happened on purpose, with a start date, three specific causes, and one country that took the idea even further. In this video we trace how the American house went from a 200-year object built to outlast its owner to a stack of quiet countdown timers — from old-growth lumber and William Levitt's assembly line, to vinyl and OSB, to what "built to code" actually means, to the country that demolishes houses after 30 years. 📩 Collabs & partnerships: [email protected] CHAPTERS 00:00 The 400-year house vs the 50-year house 02:00 When houses were built to outlast you 03:30 1947: the assembly line that ended craft 05:10 The invented forest (why modern wood expires) 06:40 What "built to code" really means 07:50 The country that went even further 09:10 So did we make a mistake?
