Realize house construction financing or let it fail?

Actually, that can't be, can it?

Are we going around in circles now?

Almost 200 sqm of living space, we have the basement, we have the excavation.

Living space is already 500,000€ plus cellar 100,000€, plus slope and excavation and additional construction costs.
The thread can certainly become a neverending story, but the house construction should probably start at some point – I hope the planning doesn’t become an endless loop as well.

...
The construction price for such a house was still between 500 and 600k three years ago. Now it is 800k. That is really bad.

In another three years, it might be 1000k Euros = 1 million Euros - or more - depending on the area.

With us, the good construction companies have been fully booked for the next year since May/June for years. Actually, all craftsmen with a good reputation.

An acquaintance of ours wants to renovate his bathroom in the Berlin area. Already two months ago, the companies told him that no one can even come to measure this year.

This is nonsense for 2021/22. Even my shell builder said in mid-2018 (we started the basement excavation at the end of October 2018) that every new construction site has to accept a 12-month waiting time from the signing.

It is the same with us. We signed exactly one year ago. We hope that it will start at the end of August (if the authorities get their act together; building permits now take over 7 months).

Are they then immediately ready and waiting right after the building permit?

For 3 people, 200 sqm + basement is not much? I think I live in a different world :) ...

We have about 170 sqm for 3 people spread over 6 rooms. Considering the number of people, the rooms are already comfortable. A small guest room/office on the ground floor. A separate "ladysroom"/chill room on the upper floor. An office/"mini cinema" in the basement. The rooms are certainly not generously large, but sufficient. "Economically" sensible, so to speak. However, if each room were only 50 cm longer and wider, it would be noticeably more pleasant in some places. The living area would then certainly be over 200 sqm. I wouldn’t call it too large then. At least not referring to our floor plans. However, renovation and maintenance of the rooms would also have become correspondingly more elaborate and expensive. And – as has been mentioned more than once – at some point the child/children leave the house and the parents would be left with the rooms and square meters for two, unless the house is sold and a correspondingly smaller residence is occupied. This is what happened to the previous owners of our house, who at one time lived with 5 people in the house.

To be honest, I could also make good use of 6 rooms on my own. Bedroom, cinema/gaming room, library/music room, sports room, billiard room, hobby room/game room. As you can see, even here double uses are planned. And the same again for every other family member and we’re at the 20-room villa that I actually need. Or even better, a house for each on a large estate. Unfortunately, I am just a small linemanager.
