How much roof overhang is there in a wooden house?

I also advocate for 50 cm and call you into the discussion. Could you also mix, for example 30 cm at the gable and 70 cm at the eaves?

larger than 50cm the entire roof overhang counts as built-up area and thus belongs to the floor area ratio.

From 50cm, not above. So 50cm is also included.

In a natural wooden house, it would bother me later that below the roof the tint remains, but further down it fades. I would always choose the barn look... 0cm

Hey, we are actually also building with Fullwood and have a one meter roof overhang. For reasons of constructive wood protection, I would definitely not reduce the roof overhang. If you get wooden windows, they will probably also last less long. If you do the master carpenter installation, plan significantly more for the trades calculated by Fullwood. Also expect (depending on how many helpers you have) to keep the master carpenter much longer. We had agreed on 10 days of master carpenter with Fullwood, he had to stay 6 weeks and almost all the trades were significantly more expensive. We have a blog if you want to read more about our building project. Best regards and good luck!
