Yes, we will probably hire the architect.
We still have the old wooden floorboards and want to preserve and refurbish them as much as possible.
After rough recalculation on my part, we come to around €118,000, with an architect from the circle of acquaintances planned at €1,500 and the roofing work estimated on the high side at €30,000. But as mentioned, we will know more only after the roofer has been there.
