Well, such a discussion leads, among other things, to looking for alternatives. Not only that, but one also goes deeper into the subject!
That is to say, people here keep asking forever about "kit houses" or "Swedish houses" or whatever. Basically, anything that is not as costly as this whole KFW thing.
So far, most are demotivated with short sayings like "Try to get those approved here." But in the long run, that won’t work anymore.
Many people are now aware that they can (rightly) be exempted from the Energy Saving Ordinance.
That is the beginning!
As soon as the "alternative" construction methods realize this, and in my opinion it won’t take long, they will spread here and compete more intensively for customers.
Added to that is the general forecast that the construction boom has reached its peak. And what comes after a peak, we all know. The only question is, how long will the peak last?! I don’t think it will last 10 years. If I had to bet, I would bet on 5 years. That means, I think that in 5-7 years the house prices for new builds will be back where they were in 2014-2015. Etc...
