Construction costs are currently skyrocketing

You are welcome to take a look. Denmark banned the new construction of oil and gas heating systems in 2013 and the replacement already in 2016. There was nothing apocalyptic or astronomical about it.
Maybe it's because there are fewer Monday walkers in Denmark?

Or because the entire energy structure in DK is different? Because district heating networks have already been built for decades even in small towns? And these were already available to a large portion of the population at the start of these bans?

Is it because DK is building a bunch of offshore wind farms while here we are still talking about hearing damage in harbour porpoises?

L stones set 50cm high €80 per meter including everything in anthracite

To contribute something to the "construction costs"

How wide? Fair-faced concrete or "concrete rough"? We pay €380 per running meter for the high-quality ones in all-around fair-faced concrete and a little more than half for the "ugly" ones. Each 100cm wide.

€80 is a top price... For 15.8m, we should get a little over €6k gross, I almost cried :)

Of course, everything works perfectly.

In my neighboring village, there is a biogas plant. It produces electricity and heat. And so the village is supplied with district heating. 200 residents are happy about low energy costs and emission-free heat supply.

Unfortunately, the plant is only sufficient for this one village. The construction of another plant to supply two more villages with heat, including my village, failed due to bureaucracy.

Such opportunities are unfortunately only available in sparsely populated rural areas. The existing biogas plant also requires 1000 hectares of cultivated land for corn. That is, for those who don't know, 10 million square meters of farmland. You could also grow wheat on that. Instead of producing heat for 200 people, you could also produce 8 million kilos of flour and thus feed thousands of people for a year. But this is just as a side note.

So we have neither the farmland nor the district heating networks nor cheap electricity. Whoever has the highest electricity price worldwide and electrifies their heat generation will have a very hard time. And comparing us to a sparsely populated territorial state like Denmark is completely out of touch with reality. Or if I pay 4 cents for electricity, as in Norway with significantly higher incomes, then my heat pump can also run full power with an electric heating rod in winter and heat. In Germany, however, it would be financial suicide at ten times the electricity price.

Why does everything have to be sugarcoated? The German energy transition is a mess and is destroying Germany just like so many other things.

Does anyone here happen to know what you have to pay for Knauf gifafloor presto 32 or 18mm dry screed? On the internet, I have only found it at smaller shops and Hornbach. Are prices over €50 per sqm actually realistic, or do tradespeople usually get it significantly cheaper?

The idea that my grumpy over-70 real-life neighbor Uwe writes down his observations as a hobby in many but uninformative sentences in a house building forum and always comes to the Sarrazin-like conclusion "Germany is abolishing itself" is just as cute as it is frightening.
In this spirit:
Uwe, if it’s really you: Cheers! Grab a beer and relax.

How wide? Exposed concrete or "rough concrete"?
We pay 380€ per running meter for the high-quality all-around exposed concrete and a little more than half for the "ugly" ones. Each 100cm wide.

80€ is a great price... For 15.8m we are supposed to pay just over 6k gross, I almost cried :)

It's anthracite but only because it was probably available faster, I would have taken the ugly ones too because I can't see it.
From 1m height it will probably get extremely expensive because then it has to comply with standards and the stones are reinforced, etc., I was told.
Luckily, you only do it once, that's what I often comfort myself with when building a house nowadays ;)
