My "ex-house" is a wooden house from Stommel Haus. These are 9.5 cm log boards on both the inside and outside with wood fiber insulation panels in between. So more or less a solid wooden wall.
Unfortunately, this method of construction is no longer offered. Apparently, it was no longer profitable; the market simply wasn't there.
Clear advantage: the living climate!
Disadvantage: high maintenance.
Also, depending on the surface treatment of the interiors, you sometimes feel like a woodworm. We compensated for this back then with very high rooms and an open design.
However, I would not want to build like that again – despite the brilliant room climate!
Furthermore, it was not exactly a bargain. The thick wooden walls have to be paid for.
However, in terms of workmanship and cooperation with Stommel Haus back then (move-in was 2006), it was top!
