Your average surviving 100 year old house, maybe. I’ve seen enough of them to realize that though they may be build out of wood that is old and hard and thick, they’ve tons of issues that just pile up over time.
Perhaps it is different in temperate climates, but old houses can be an absolute hassle.
Wood isn’t used because it will last forever - brick and stone are better for those purposes. Wood is excellent, just not the best. It’s much more efficient though.
That’s probably a big part of it, but of course making anything stand the test of time is extremely difficult.
Maybe you live in a tropical climate but wood can last 100s of years as long as the roof is maintained. Unless it is a timber house the outer walls will need replacement every 100 years though.
