There's a youtube channel shadiversity that I haven't watched in awhile. It is mostly about fantasy media and swords but also spends a lot of time on medieval building techniques and clothing. One of the more interesting videos I watched talked about how before and even after saw mills could process and produce different sized boards people would 'grow' them instead by trimming trees to produce long straight narrow branches. There was even a still living example in some English village that some trimmed 100 years ago before the process was completely stopped.

This also reminds me of those Japanese temples where in order to preserve the institutional knowledge of how to rebuild the temple in case of disaster the monks tear it down and rebuild it from scratch every 30-40 years assuring the next generation has experience.
