I understand it as you also like to plan a nice house, with a desired room program etc., but that for you perhaps things like Smart Home, Q3 wall quality etc. are rather aspects that are not so decisive for you, as they only subjectively increase value.
No, completely wrong.
Certain things, especially aesthetics, are important to me and us in and on the house, and that was also implemented. But ultimately, the house is not the center of all areas of our lives, but only a means to an end, to live as comfortably and beautifully as possible.
Building an impressive house for its own sake is one thing. Another is when you start saving on things that are common at this house level (garage door to the interior or also, which I only just saw now, a kitchen exit to the "kitchen terrace").
In this respect, I found it completely absurd when you started to continue planning the shell so "playfully," but save on normal things. The main thing is impressive from the outside. Everything else will be done over the years.
I certainly have nothing against services that can wait. But with you, the focus on the house shell is very noticeable.
That somehow doesn’t fit.
The house, building the house, is a milestone in life, but there are other, not plannable, more important ones.
We currently have 2 houses, one similar comparable to yours, the other approximately. Both unsellable for over a year. Reasons for separation. Both are now rented out, are being "worn out" by strangers, the gardens are stagnating.
Above a certain budget, a house is no longer easily sold. Above a certain sum, you build yourself.
And the higher the basic standards (the house is also just a placeholder), the greater the risk of feeling trapped in a golden cage.
