So we are currently also planning a KFW 55 house. It is to be built monolithically with 36.5 cm porous concrete (PPW2 is specified). In addition, there will be floor slab and ceiling insulation as well as an air heat pump. I also hope that everything will go through like this. However, the general contractor has had all thermal bridges certified at high cost (detailed proof) and therefore has less flat-rate deduction for the thermal bridge calculation. According to their statement, the KfW 55 is achievable, which I really hope for because our KfW loan depends on it.
