Build a house and cellar for €220,000?

I just take note that I have received a "Verwarnpunkt" for this response. What is the point of that and why did I receive it? Is one not allowed to express their opinion here?

Please express yourself, I don't want to attack anyone, but a little criticism/questioning of general statements should be allowed, right? The website you mentioned does not work.

So now I specifically visited your website.
So you sell houses and can provide independent advice here?
You yourself live in a custom-designed architect’s house? That is exactly the opposite of your "daily business."
If I buy a house from you, I pay all incurred costs plus your profit. So why should one turn to a prefabricated house company?
Thank you for your informative answer.

Yes

Do you live in a custom-designed architect's house yourself?

Yes

That's exactly the opposite of your "day-to-day business".

No, how do you come to that?

If I buy a house from you, then I pay all incurred costs plus your earnings.

Well, I certainly hope so.

So why should one turn to a prefabricated house company?

Well, because I have already built over 200 houses, and you?

Thank you for your informative answer.

You're very welcome.

Gladly, what specific question do you have?

Yes

Yes

No, how do you come to that?

Well, I certainly hope so.

Well, because I, for example, have already built over 200 houses, and you?

Very gladly.

Gladly, which specific question do you have?

If you want to build a custom-designed architect house, you don’t have an advantage with a "prefabricated house company," do you?
If you buy through you/prefabricated house company, you pay all incurred costs plus your profit. Why should one do that and not turn to an architect and get quotes from the individual craftsmen?

If you want to build a custom-designed architect's house, you don't really have an advantage with a "prefabricated house company," do you?

not all companies offer this, that's true.

If you buy through you/prefabricated house company, you pay all incurred costs, plus your profit.

Yes
