New single-family house - city villa floor plan and exterior view

Thank you first of all for the answers
The bedroom and dressing room are planned as intended. Only the bed and a small chest of drawers are supposed to be in the bedroom, as we only sleep there. The planner personally did not find it ideal either, but from our point of view it is. Since we have to get up at different times, the first person getting up does not disturb the second, and you can calmly get ready in the bathroom and dressing room without having to go through the bedroom again.
The storage room in the kitchen is about the same size as at our parents' place; we measured that.
All the heating technology and, prospectively, for a pool installation in the garden (although that is only in the distant future) is to be placed in the small basement.
With regard to the living/dining room, we also thought about it and decided on a cozy sofa corner, which is also intentionally somewhat narrower. However, the drawn sofa is too large, you are right about that. The table does not necessarily have to be placed as drawn.
We plan the coat rack/shoe cabinet under the stairs.
The fireplace is correct but is supposed to be closed off in the living room; the one in the kitchen is the refrigerator. A door in the kitchen would be worth considering (where the refrigerator currently stands, then we would only have to extend the terrace).
45-degree walls are wasted space, but we also like them very much and do not want to miss them in those spots.

Budget is not sufficient

The staircase next to the door fits a small settlement house
Hallway too large
Storage room next to the kitchen is too small. What is supposed to go in there? With kitchen cabinets you can store more.
In the living room, draw proper furniture to scale, including TV and table with walking space.
Walking distance kitchen terrace far and impractical
What hobbies do you have?

Dressing room way too big or is someone collecting handbags or 200 pairs of shoes here.
Children’s rooms have the worse orientation and are too small.

Overall, the rooms are unbalanced.

For the specified budget, I do not see the house. The interior layout seems somewhat outdated, I would critically review the points of criticism mentioned again, and you can tell that there are still two of you, otherwise you would plan many things differently.
