Developer or architect - costs

Architect, not general contractor!

Again, I think it’s great if it worked out for you.

But you’re lumping a lot together here just as broadly as you accuse others of doing.

First of all, very few builders even have the time to handle individual contracts themselves.
Furthermore, you don’t actually know how much you saved compared to using an architect.
You saved his fee, sure.
But do you know if you would have gotten the same prices through an architect?
You might have ended up with completely different craftsmen.
Maybe some things would have been done differently and possibly cheaper, without being of lower quality, simply because you didn’t know about that execution variant.
Nothing against your research (which I would recommend for all building variants, by the way), but you can’t make up for the overview and professional experience in half a year of internet research.

That doesn’t mean what you did was bad. I find it very admirable.

But a direct comparison is very difficult, and to claim you saved 100,000 compared to an architect is simply not possible.

A general contractor/general builder might be different.

Not an architect as the general contractor!

Again, I think it’s great if that worked for you.

But you throw quite a few things in the same pot just as you point it out the other way around.

GU/BU that might be possible.

What more can an architect do? In the end, 100000 are not enough that we have saved.

Still better than shoving a multiple into the mouths of architects and general contractors.

But you also mentioned architects and made a false claim (negotiation cuts architect in)
Compared to general contractors may be, I don’t know your offers.

I don’t know how rural you live, but if you live even remotely in a densely populated area you can never know all tradesmen of all crafts.

Again, for you it probably works great and compared to general contractors the comparison may be better possible. Compared to architects you simply don’t know.

That's true. I can't say 100% that I'm an architect. I live in a very rural area. Are you an architect? Because otherwise, I don't understand why you're getting upset.
