Update:
We were at the architect's on Friday and discussed some changes. Overall, the floor plan remains as it was. The window in the utility room will, of course, be installed, and this room will be slightly smaller.
In the entrance area, a glass partition wall will be added between the hallway and the living-dining area. Under the stairs, there will be a kind of storage closet as additional storage space. Built-in wardrobes will be installed in the entrance area/hallway, recessed into the wall (the wall to the office).
In the parents' area near the bathroom and in the bedroom itself, sliding doors will be installed to allow separation "just in case." More built-in wardrobes will be integrated into the hallway to provide additional storage space. I wanted the parents' area to be mirrored (because of the wastewater pipes), but the architect said it would be difficult with the wastewater pipes since the toilet currently lies directly under the wall on the ground floor, and otherwise, the toilet would end up directly in the dining room, where there is no wall.
The 3 additional bedrooms or guest rooms will be slightly adjusted. The guest room should remain in the upper area since it is mainly to be used by family or very close friends.
The revised floor plans and corresponding views will be available in January. The main problem we currently have is the exterior facade.
Does anyone here perhaps have ideas for a light clinker that would fit? Actually, we wanted white plaster, but we were advised against it.
As an example, I have attached a picture.
Looking forward to further responses.
