Interesting to hear. So really €330k just for the renovation without the purchase price etc.? That's almost €2450 per square meter - you can build new to that standard for that price. I got the first offer yesterday if we have the windows installed. I had to sit down first to process how much more expensive that would be compared to ordering windows online. KFW70 was declared feasible by a consultant on the phone as well. However, I am currently facing the problem that everything must be certified in some way for the subsidies, and so far no energy consultant is willing to do that for self-performed work.
