According to my understanding the building envelope/insulation:
Exterior wall 0.14 W/m²K
Roof 0.15 W/m²K
Triple glazed windows, only Ug value given 0.5 W/m²K
Floor slab 0.15 W/m²K
Front door 0.8 W/m²K
Floor slab with perimeter insulation 120mm 0.35 W/m²K (under the floor slab)
Additionally 80mm at the end face of the floor slab (XPS)
+ already mentioned heating system + ventilation system
Obvious things, like missing painting work on visible wooden parts on the outside, missing floor slab or sanitary installations would have already caught my attention.
I am more concerned about points that are not immediately noticeable and can really cost a lot. I am also aware that the standard scope of work description really only covers the absolute standard and any changes will be expensive.
Still, thank you very much for your answers, I probably first have to develop a feel for a reasonable house price.
