Floor plan EFH165 sqm first draft - Architect dissatisfied

We have not worked with any architect yet, so we do not know what kind of sketch to expect, what it should look like.

Exterior walls, window positions, dimensions, and doors should be recognizable at a glance.

You are customers! (a customer pays and orders, that is a significant difference from a petitioner). Be clear about what you want and communicate it:
EITHER rectification, meaning the architect should maintain his fee entitlement but deliver an acceptable countervalue in return
OR agree on acknowledgment of the failed attempt, part peacefully ways, and settle on appropriate remuneration for the (in my opinion, poor) services rendered. After all, you now have to spend money on a different planning approach.
The option "hope and be surprised" only exists if you are willing to switch from the role of customer to the role of victim!

I think creating a counterproposal is good. However, I would not try to further develop it but only use it for a short series of very specific purposes:
A. Illustration of the delta between the architect's design and your needs/wishes;
B. as a benchmark / pattern for searching suitable proven building proposals / catalog houses;
C. for an orientation request (> "setting the course"), I can gladly prepare such a request for you from the architect's design, your counterproposal, and a comparison of the two.
[...] I see you most likely continuing down the path with an independent building consultant (construction-method-neutral, this can be another architect – then probably remunerated according to HOAI – or gladly also me), I have already mentioned three of my colleagues (Beuler, Zink, and Freyermuth, unfortunately all focused on "prefabricated houses") several times (see forum search), and this "list" is by far not exhaustive.
