I definitely did not want to be offensive with expert. Then we'll stick with specialist.
... gladly also for you – so see you soon in your thread ;-)
so you find the called prices of 3500-7000€ realistic and okay?
That always depends on the service provided. Service phases 1 and 2 together are 9 percentage points of the total architect's fee, service phases 1 to 3 together already 34 (see also: "A house building roadmap, also for you: the HOAI phase model!", which I only recommend as a roadmap and, by the way, only as a fee guideline for larger projects and other target groups). Single-family home builders should also approach architects on equal footing, and not “XYZ and Partners Architects and Engineers worldwide partnership.” Housing construction for the family's own use is fundamentally a different matter, in the truest sense of the word, than for the housing market of Boomtown City. For 14k, there is at least already a small new car from Dacia and Mitsubishi (which in my opinion is a legitimate benchmark for the average consumer).
