Our stair builder says he doesn’t notice anything yet, as it is more about structural solid wood rather than joinery wood. However, he is already preparing our stairs in such a way that we won’t be affected by upcoming price increases.
Our contract for the house still has a fixed price until December 2021. We should manage that, as the house will probably be erected in November. As a [Ausbauhaus], we also get all materials for the interior construction (structural solid wood, insulation, drywall sheets, etc.) from them (if there is still material available then :D). The architect was still quite relaxed and said everything will be fine.
Still, all this stresses me quite a bit, as I am not a very relaxed person. I still hope everything will go well.
