Brief interim report: The 2nd visit is done and there are some photos and updated floor plans (my first attempt with Sweethome3D).
From the ground floor upwards, almost all windows are already in newer sizes. Probably not final. It might look a bit wild. On the ground floor, they are this large because after removing the old roller shutter boxes, only air remains.
The interior walls are all stacked. So we should not simply remove the walls in the kitchen and living room downstairs. That means everything upstairs will be removed and replaced with lightweight construction. There is a timber frame with support beams in the masonry - we will expose it and leave it as it is.

The structural engineer saw it quite optimistically during the inspection, but we are already feeling dizzy at the entire effort. It was already incredibly nerve-wracking that the bank wanted estimates for all costs. Please deliver in 1.5 days – luckily now it went through with the overall list drawn by the structural engineer.
