I have built since few year my first wood house (Euroclass A+) and have had very limited "long-term" experience of wood structures for small "garden-like" construction, in summary: they are damn good in terms of thermal isolation, fire resistance (yes, wood burn, but structure sustain heat more than concrete!), and maintainability (especially to change something inside, if wood is properly designed) however we should copy Japanese way of wood fitting to avoid metal fasteners (screws etc) because after years they tend to loose simply due to internal forces in the wood structure due to thermal dilatation etc.

Also I do not really now how long steam brakes towels can last, they are plastic and plastic normally do not last longer... Formally they are guaranteed 10 years. If we have designed implants properly they can be changed with a long but not extreme work however...

Another point is fragility in general: to have proper insulation, at least in EU but I assume also in the rest of the world, we use "VMC" (forced ventilation with air-air heat exchange) and while they are essentially brushless motors running calm and slowly they have filters, humidity regulators (that are essentially "heat pumps/fridge like machines) etc and again I do not know how much they can last in years.

With a broken ventilation living it's hard, I experienced it very well since I have start inhabit my house before it's completion and I have to keep windows opened a bit or I literally suffocate inside in around 12 hours... And the resulting "closed smell" was really high... Probably that's the very same thing for modern concrete construction but that's is... Without some machines and electricity it became really hard to live inside...

BTW I'm happy and I note to some likely to downvote in these arguments: this imply little buildings like two/three floor maximum. We can build taller building in X-Lam but they are more experiment than reality. So draw your conclusion. The population model for modern wood houses it a Riviera model, not a skyscrapers town.
