Floor plan design for a new single-family house - 610 sqm plot - opinions welcome

We are building (unfortunately) without a basement, so a certain amount of storage space naturally has to be represented in the upper floors. Our list of requirements has resulted in these floor plan dimensions.

that is an important point ... we also have great respect for our first offer. Then it will be seen whether we have to go back to the computer to save another third or if it works like this.

These are two completely different things and not meaningfully convertible against each other: anyone who builds storage space to replace warehouse space is fighting fire with fire, and ends up throwing out the baby with the bathwater:

You cannot simply scale designs according to the budget; budget clarification belongs to the basic investigation, essentially at the transition from service phase 1 to service phase 2.
.
Lay planners focus too much on a nice arrangement of their wishes - although one must actually wish for everyone that their wallet protects them from overindulgence, because a house does not become more beautiful by being larger. At some point, some education policymakers must have come up with the irresponsible idea to remove the story of the fisherman and his wife from the reading books :-(

Phew, these clichés again...
Dear 11ant, tell me what the sqm gross floor area in Lower Saxony will cost in the next two months for this single-family house.
That would be interesting!

Prosaic remarks don't help me and probably most other readers of this topic.
Maybe you should focus your further comments on other subject areas.
The forum is big enough and you can still collect plenty of comment points there.

By the way, I never collect points anywhere, even if every cashier asks me for them.

[*]Living / dining / cooking somewhat around a corner / angle, not straight and narrow -> cozier
[*]Space in the living room for a Christmas tree or a decorative piece of furniture (often missing in smaller floor plans)
[*]Space for 10-12 people to sit comfortably (barely enough even here?)
[*]Kitchen with pantry (we currently have a very small, awkward one, and although I hate how cramped it is, I still love it)
[*]Large office on the ground floor – a given for us (remote office), and it exceeds most "standard" single-family house floor plans
[*]WC (without shower is enough)
[*]Wardrobe behind a partition wall, preferably a niche – currently open in the hallway and visually too chaotic for me
[*]Technical room farther away from the living room & separated from the utility room (I could do without this, but it’s nice to have)

Well, some truths are just the same for Beckers as for Schmidts. And if you’re really still calculating "budget by price per square meter equals possible house size (whether you actually need it or not)," then it seems to me you haven’t understood at least my previous post. You are seriously underestimating the readers (and/or confusing the role of a thread opener with the non-existent role of a thread owner). I’m not writing here just for you: turn around, behind you—as with other thread starters—there are on average ten readers (statistically speaking)—and that’s not even counting the “silent” ones. By the way, I never collect points anywhere, even if every cashier asks me for them.

Payback points are great though, I use them to pay for a complete drugstore shopping trip every half year for three-digit euro amounts.

I just don’t know a solution that saves a huge amount of square meters, but maybe I really have to ask a "real" architect.

I’ve looked at many floor plans, already for the last house, and again now, and with smaller square meter numbers I never find space for all that. Or I have to ask for an architect’s draft after all. What would one roughly pay for something like that, if you just ask someone to make a draft (without wanting to build with it afterwards)?

Tense forum members are probably to be expected everywhere nowadays, unfortunately.
