Once again, we must distinguish the industrial substrate from the profitable world vs. the industrial substrate from a sustainable world.
The effects on resources of all kinds are absolutely not the same.
In one case you have to produce to make money, in the other case you have to produce for the need for use and less and less, since the goods are durable.

We have made progress in thermal technology from these old Brittany stone houses. Hard winter without a chimney
There are plenty of ways to make wood sustainable: do not expose it to water (roof overhang), retified wood, surface burning of wood, choice of wood species ...
Therefore the durability of wood is not a problem but rather a solution for the future.
The ideal is to mix insulation / wood / stone / glass, in order to achieve bioclimatic or passive habitat
In my opinion, their "Tiny House" demonstrator lacks thermal inertia.
