Is all of this realistic? I would appreciate your opinions – thank you very much!!

You have already posted a cost estimate from an architect here before.
So you do have a comparison, right?!?

Is it the same architect?
Is it the same house, just larger?

....another architect, now with a concrete design!

Did I overlook something? Is there anything special about it? A passive house with extremely luxurious fittings?

It seems incredibly expensive to me...

Even for BW definitely too expensive. I also find the architect’s fee to be quite steep. I think you’ve ended up with a bit of an artist.

Architect (fee zone III, middle rate, service phases 1-8, 5% additional costs) approx. 90,000 and additionally structural engineer fee zone II, minimum rate) approx. 23,000
