Dude, seriously. It's not. I have never seen a wooden support structure in Belgium. We might have some wooden cottages in forests, but a wooden support structure? That's just insane.
I'm telling you, the flying buttresses and band boards, and floor joists are all wooden.
That is the main support structure. The Steel would be too heavy and expensive. Concrete would be possible though.
Andries, I think you are out on this one unless you can prove to me otherwise, as I spent about 8 or 10 months framing houses.
