and your walls are thicker your SHON is high because as its name tries to indicate it is calculated outside the work (so outside the house) ...
So here are more taxes to pay if we make stone walls and less if we make wood frame well sized ...
hehehe ... another advantage ...
This is exactly my house: wooden frame walls 15 cm thick filled with insulation (rock wool: in 1985 there was nothing better) + exterior cladding in Red Cedar rot-proof on battens (the cladding is 20 mm d '' thickness approximately; Red Cedar is very ioslant). Can it be ordered at SIBAC (I don't know if it still exists) in La Rochelle or Sète and perhaps in Le Havre? (the ports where it arrives by boat). I bought it like that without an intermediary; a local transporter delivered me a large package of 6 m X 1 m X 1 m, enough to cover 250m2 which I then placed alone.
This Red Cedar is very easy to cut and install (very light and in addition excellent smell when sawing ). Above all, it has the advantage of being rot-proof so it needs no processing.
Atqui => if you're interested, I can give you some information.
I have lived in this house for 20 years now and I am very happy with it. Excellent comfort (no cold walls), no cracks (frame placed on concrete studs every 3 meters + reinforced concrete sill 50cm high poured on these studs: then it's a construction game: the panels are built in the workshop and then assembled on site.
In the event of an earthquake: resists tremors very well, but this is not the criterion of choice in my case! It would be much more "fragile" in the event of a tornado (winds at 200 km / h (see what has just happened in Florida where the houses are made of wood). Another drawback: If the warming is confirmed, the areas infested by termites will progress to the North in France! if the wood is well treated (in my case in an autoclave / vacuum under pressure, well isolated from the ground, I hope that these bugs do not attack it).

It withstood the storm of December 1999 very well. To tell the truth I was not at ease because it has a gable facing due west and the gusts were blowing very hard on this side. We could hear some crackles in the structure !! (it's like the reed: folds but does not break .... see La Fontaine's fable "The oak and the reed).
