> time-limited construction technique To be fair, almost all buildings, especially residential, are time limited artefacts. Even if FLW knew some of his works would become protected heritage / conservative buildings, they're still private constructions without the budget scoped for institutional buildings designed to last 100+ years. My memory is FLW already had reputation for going over budget more often than not, there was never much resources dedicated to seriously evaluate longevity of the different building systems he was experimenting with.
