Floor Plan Check - Single-Family House with Double Garage

I would really consider changing the staircase to better design the upstairs rooms.

The staircase belongs in the center, specifically somewhere in the cloakroom/pantry area – this can also be designed individually – so that a sensible and neat room layout can be planned. This way, there won’t be a central ballroom and stylish children's rooms as well as a cozy living area can be designed with reasonable size. It is sad that the "construction technician" apparently adopted all the amateurish mistakes without seemingly providing advice, or at least not successfully. I warn every time someone thinks they know how they want to live with layman’s understanding. A non-existent budget limit does not replace expertise. It would be better to invest some of the budget wisely in a good architect. With a written room program, they can certainly design something good, which then can be discussed here not only disparagingly but appreciatively.

Draftsman is a vocational training profession, not an academic one; design techniques are not part of the training content here. What the draftsman produces meets the expectations of the developer, insofar as it appears professionally authentic as a drawing (actually only: it comes across as somewhat washed and combed, where the layman's drawing stylistically reveals itself as "not professional").

As much as I wholeheartedly agree with you: the remuneration of the architect is a dreaded hurdle. It is easier to take out a loan for the land and the actual house, even for a fitted kitchen, since there is tangible material value for that. A plan is in the worst case only a collection of expensive graphics without artistic collector's value. And – as is also true for consulting services (except those of the energy consultant) – no construction loan and no building savings contract are available to finance them. You pay for them in the dimension of an annual vacation, practically out of the "vacation fund." Yes, it is worth it (unfortunately not with some architects), but at first it hurts the savings account. In this respect, of course, I understand all my non-clients (and those of the architects).

I do not see any terrain reason for the fast empty cellar.

Neither do I. But the beloved cats (for whom the cellar is planned) are allowed in the ground floor anyway. :rolleyes:

But yes indeed.. you're welcome for the tips.

Impatience is actually my thing. Let's see if anything else comes here.

I didn't want to show my impatience - the OP won't be contributing anything more anyway. I just wanted to practice politeness if the OP doesn't.
