Floor plan of our dream house

this is somewhat exaggeratedly expressed, but probably hits the core of the matter. For me(!), the classic "architect's house" is a house completely out of place in its surroundings, maybe with a huge glass facade to guarantee the wow effect. A soulless glass-concrete block that in no way reflects its inhabitants, but only an eternalization of the inventor. Extraordinary, but impractical. That is my image – I repeat: MY image of an architect's house.

Your image then reflects an insufficient requirements definition. If you write "no glass palace" on your requirement list for the architect, then he will not design one for you either.
How good the architect's result will be depends largely on how good, detailed, and complete your requirements description is. However, if it is, then I dare to claim that the professional can create a design that puts your own design in the shade.

You can also talk to architects. For example, I spoke with one who was a fan of a certain construction style and always raved about it. Well, after two preliminary meetings it was clear: We didn't get along.

And no, not every architect wants to build a glass palace. Unless they specialize in glass palaces and have on their website: "You want a glass palace? I am your architect!"

yes, I wanted to minimize the circulation areas. is that wrong?

Sort of. It is not "wrong," but paradoxically, it backfires with an extremely high success rate. When laymen try to minimize circulation areas, labyrinths regularly emerge whose total area swells (anti)proportionally to the efforts at economizing. Like in the "template" of the sorcerer's apprentice: the split brooms bring twice as much water. I consider it extremely important to strictly and rigorously separate the two pairs of shoes A) "enjoyment of one’s own planning games" and B) "working on the serious planning process," at least as much as service and schnapps. Not all architects are talented planners, but most are at least well trained, and in any case 99.75% of them are no "star architects." I also perceive the latter as rightly avoided, which fortunately is quite easy, since the candidates proudly boast of their otherworldly palaces on their websites. Since I am "only" active nationwide as an architect finder in Germany, I personally know only one in Austria. But successful architect search is no sorcery. Further hints on unsuitable candidates can be found here especially in those of my posts where is mentioned. And possibly architects of houses discussed here from "your league" ;-) also work in Austria - I’ll call , , and into the discussion ;-)

And quite plainly, many architects are also visually recognizable whether they count themselves among the disciples of a very specific "school": by the Gropius bow tie, the Corbusier glasses, or the Saab in front of the door ... *) the architect should have taken the opportunity to make at least two of their own napkin sketches before the client shows them their own planning attempts

Mine came by bike – but since he used the word "Zwerchgiebel" in every sentence (making a post-coital face) whether it was about the cellar, the ventilation, or the garage foundation, we didn’t get further than an on-site visit and a first (paid) draft. With Zwerchgiebel, of course.

A garage foundation with a Zwerchgiebel is certainly a dead-sure sign of a reality-detached architect, but unfortunately also extremely rare. On the other hand, the designers of Doge’s palaces milled out of solid material can be recognized by "awards" that couldn’t possibly be transported in a bicycle basket ;-)

(...) doge palaces milled from solid (...)

Brilliant, I have to remember that!
