What is the most important/basic question about the floor plan, summarized in 130 characters?
Should we completely rethink the design of the staircase and the upper floor?

Congratulations on the plot!

Try using a side entrance; this will give you a more practical hallway on the ground floor. The staircase is a half-turn design but follows a standardized shape. Your bathroom above the staircase won’t work as planned anyway.

Try a side entrance, that way you’ll get a more practical hallway on the ground floor. The staircase could be a double-turn design, but standardized in shape.

Thank you very much!

I’m not sure if access from a side other than north is allowed, since according to the development plan, semi-detached houses must be built.

If I understood the staircase even a little, I might be able to say something about it ;-)

On the other hand, I am clearly confident about that.

This definitely applies to the shape, volume, and style of the house. I am sure it does not apply to door and window positions, at least not to the inconspicuous ones.

After signing the contract, I am ready to have the first meeting with the architect next week.

Your feedback on the attached plan would be greatly appreciated.
