Floor plan optimization terraced house 160 sqm, approx. 145 NWF

Can you tell me the exact external dimensions of the [OG] once more?

The upper floor measures 11.0525 m x 7.3025 m. The wall thicknesses are 30.25 cm on the left, 36.5 cm at the top and right, and 42.75 cm at the bottom. If you want to be very precise, the right wall of the lower right children's room ([Kinderzimmer 2 bei mir]) is 42.75 cm.

I quite like your layout. If it were mine, I would still try to get as many centimeters as possible for the kids:


For that, large sideboards under the window in the bedroom. The first step of the staircase in the ground floor was built over in the upper floor.

Is also a good idea. Sure, every centimeter helps the kids with the size and the parents' bedroom is more than enough. But I am already very happy that the current sizes are being achieved. And if you then imagine the grateful look of the teenage daughter who adores her parents because she has such a beautiful roof terrace in front of her room ... ;) That's how it works with teenagers, right?

First step of the staircase landing on the ground floor was built over in the upper floor.

Do I understand correctly that the staircase landing is at the top of the plan? Probably so that you don’t fall directly down the stairs from the bathroom?

One point still gives me some concern with the design (apart from the storage space, but I’ve basically checked off that point). The upper room wall of the right children's room would certainly have to be load-bearing. Do you see any problem with the statics there? I assume I will get this as feedback from the architect and would already like to prepare an argument. What is your/your team's assessment?

Well, I rather think that they hide away in their rooms all day and turn the music up full blast. Or is it different nowadays? Unfortunately, I'm not up to date on that. In any case, they often spend a lot of time in the room and quite often bring the whole gang along. Therefore, it shouldn't be too small.

Above all, so that the bathroom door can shift as far as possible to the left on the plan. Otherwise, the bathroom gets too big and the sideboard can’t fit in the bedroom.

One point still gives me a stomach ache with the design (aside from storage space, but I’ve actually ticked that off). The upper room wall of the right kids’ room surely has to be load-bearing. Don’t you see any problem with that structurally? I assume I’ll get that feedback from the architect and would like to prepare an argument in advance. What is your/your team’s assessment?

Normally, that shouldn’t be a problem. Roughly speaking, support beams are only needed for spans of about 6 meters or more. Also, the wall between the kids’ rooms doesn’t need to be that strong and heavy and there’s nothing above it anyway.

Thanks, I had overlooked the context.

Normally, that shouldn’t be a problem. Roughly speaking, support beams are only needed from a span of about 6m. In addition, the wall between the kids’ rooms does not need to be so strong and heavy, and nothing is above it anyway.

He was actually always concerned about two points:
- The walls from left to right should be load-bearing and accordingly have a corresponding wall in the ground floor beneath them.
- The lower right corner of the upper floor is critical for the current span, since it is hanging in the air in the ground floor below.

But alright, let’s wait for his feedback first.
