The entire floor plan is somehow "complicated" and in the process, so many real, usable square meters are lost.
I agree, that's why empty square meters arise: for example, right at the entrance between the door and the stairs, the girls' dressing room, the hallway upstairs next to the stairs, the kitchen could also be ergonomically smaller, and last but not least the living area/bay window. I don't think it makes sense now to torment this design even more than it already has been. It certainly did not have some mistakes at the beginning. For example, the hidden entrance to the kitchen, the living room/bedroom/office as a walk-through room... everything can be done differently, just not if rooms block each other and the stairs as well. Potential savings would be in the fireplace (10,000) and in the mullioned windows. A carport can also include a great storage shed. If I may say personally: I don't think the location on the plot is good. Garage in the north, driveway in the southeast would have resulted in bright windows and a great west garden. So now the sun is unfortunately not included at all. Quite the opposite: it is where you don't want it and not where it is needed. But well: not everyone wants sun in the living area. But the bedroom should be taken from the south there; rather a children's room should go there. The bedroom should also be accessed through the dressing room so that the dressing room serves its purpose. And then: draw your dining tables with the correct dimensions, and then ask yourself if you can quickly dash out of the kitchen when the table is occupied. In my opinion, a seating area is not planned in front of a door. The symmetry, by the way, supports the undesired urban villa character. If the windows were planned a bit more mixed, the facade would be a bit livelier – urban villas often seem somewhat dead because simply the tension in the structure is missing.
