How does the maximum height of 6.50 meters (21 feet 4 inches) work?

The wall height is measured from the top edge of the ground level to the cut edge of the outer surface of the exterior wall, including the surface of the roof.

Such a design is allowed; we have had it verified.

And this has now been shortened? What about the terrace? Is that permitted separately?

Ideally, the terrace should also be within the building envelope, but since the floor area ratio (FAR) allows for a larger terrace, an exception in the building permit / planning permission should be possible.

So, eave height?

What do you mean by “had it checked”? Is it permitted for your house, and is the neighbor with the twin house building the same way? And what about the building envelope/planning permission?

You know: everything is different here now… if you ask three questions, you get answers to two or three—if you’re lucky. Instead of stepping in with something like, “Sorry, everything is different, here’s the correction, I’ll explain,” you make us piece everything together ourselves. I might have had time this month to do some drawings, but that time is wasted now. I also don’t know anyone here who is still interested in this…

That already looks like a "proper" construction drawing—actually "a bit too detailed" for a preliminary building permit application—so what are you still tinkering with in your drawing program?

In short, the municipality was helpful and gave us some advice on how to update the original plan from WeHaus (based on our comments – unfortunately, the local building regulations regarding the municipality’s design guidelines were not taken into account). The attached plan is exactly the updated version.

I’m sorry if I wasn’t able to anticipate or satisfactorily answer some questions. Since we are requesting an exception to build a wider structure, officially the attic is unfinished and the roof pitch is being reduced to address any concerns.

Dear members,

I believe the last attempt was a colossal failure. I haven’t given up yet and am presenting another update here. I look forward to your feedback.

The stairs are not drawn precisely, but the dimensions are 3.2 m x 1.6 m (10.5 ft x 5.2 ft).

I really appreciate you taking the time to review it.

Good luck

That already looks a bit better, except for the exterior views, which are too cluttered.
Furnish the bathroom on the upper floor differently. Place the door to the bedroom opposite the bathroom door and rotate the bed.
If necessary, reposition the children’s bedroom doors to enlarge the bathroom.
Use a lightweight partition wall between the children’s rooms with a staggered layout to “hide” cupboards there.

Stack the windows on the east side. In the living area, a large corner window (floor-to-ceiling) could enhance the dining space, and in the living room, two meters (6.5 feet) of floor-to-ceiling windows. In the dressing room, a raised window visually connected to the bathroom window.
A standard double-winding staircase is sufficient.

With three children and many overnight guests, I would separate the living room as a small TV room and swap it with the kitchen. This would create a nice, spacious kitchen-dining area facing the garden and terrace.
