Panoramic fireplace: Camina or Brunner - or something completely different?

Thank you all for the diverse input, it is really very helpful. Building a house is a tricky thing - you actually have to become an expert in everything within a very short time in order to take as many contingencies as possible into account.

I can only agree with ruppsn. It all depends on the chimney builder, he must not just be a salesman. We also had to go through 4 before we found a suitable one. Unfortunately also one of the most expensive.
