Serious question: Do you have statistics on that? I mean those that show that in the last 30-40 years there were also phases when construction costs decreased.
Anyway, as I mentioned earlier in the thread, I find it hard to imagine that it will become cheaper again for the average homebuilder in the foreseeable future. Energy prices are rising; interest rates are rising; labor costs are rising.
When it comes to the rise in construction prices, the following must be distinguished. The trades that are largely financed by credit have increased massively in price. The trades with small order volumes have increased much less.
There is therefore a clear correlation between rising prices and low interest rates.
The massive increase in order volume in certain trades was only possible through increasing the level of indebtedness.
Mainly electricians, heating engineers, and roofers are to be mentioned here. Where 10 years ago a roof was covered for 15,000 euros, today it can quickly be 50,000 euros. Although material prices have not risen so exorbitantly. I ordered roof tiles last summer.
They cost exactly the same as 10 years ago.
Addendum: Simply overlay the construction cost chart with the interest rate chart.
