New construction - How to build economically sensibly?

That doesn't say anything, the question was who is building,

Is questioning everything some kind of hobby of yours?

We only answered one question without intending to make any statement.

The only thing one might possibly infer from the answers is that the small medium-sized company without many subsidiaries builds and can do so more cheaply.

In the end, you always pay the markup for the [GU]. The subs who do the work for them don’t do it cheaper than, for example, my medium-sized company. But the [GU] still wants to make a profit, of course.

Is it somehow a hobby of yours to question everything?

No, but

We just answered a question without wanting to make any statement with it.

maybe I just missed this question.

I wouldn’t claim that. Our GÜ designs a maximum of 24 houses per year, so it’s rather small.
And it wasn’t more expensive than others either.

I think, in the end, my medium-sized company, if he is not building a house himself, is often also acting as a subcontractor, and I don't believe that he is suddenly cheaper, for example, that your entrepreneur gets his profit margin. It's all just hypothetical.

A big player like Bien-Zenker or von Heiden may have advantages in purchasing. But it also has disadvantages. It needs a sales department, in my case that’s the boss himself alone. Sales wants to earn money... They print colorful catalogs, have model home parks, do advertising. My general contractor (GC) doesn’t do any of that, he doesn’t even have a website, doesn’t need one, it works anyway. They maintain model centers where you can add overpriced tiles and such and sometimes have to. My GC has nothing like that, he sends you to his building material suppliers, pick something from there. That’s included in the price, above that you pay extra. There are no site managers. Each trade has a non-commissioned officer who coordinates that, a kind of foreman, and the builder deals with him as long as their part is ongoing. Surcharges for electrical and sanitary are arranged directly with them. That doesn’t go through the GC at all. All that saves money in the end, so although he probably buys more expensively than von Heiden for example, in the end he is still cheaper. Karsten
