Floor plan 200m² single-family house, raised ground floor, existing plot, double garage

On the topic of heights, I wanted to add that the existing house basically already has pretty good values. Okay, the ceiling height on the upper floor is not great if it is actually only 2.25m. But they have a 40cm knee wall in the attic. Actually, one could go to the building authority and say that they want to build almost exactly like the house that is already there, just 50cm higher for flood protection. Then see what they say. If they reject it, there is still the option to work with a 2.10m knee wall or similar on the upper floor. Everything in between is probably negotiable. Either way, I consider it the best option to convert the attic for the parents.

By the way, I have optimized the last design to the external dimensions of 11m x 9.2m. That gives me a total of 198.2 square meters including the attic, whereby everything under 2m height is counted as half and boxed-in areas as 0. The smallest children's room is 15.4 square meters.

Thank you for all your work Katja. Our architect will be available again from Monday and then I will bother him with the height issue until he can give us an answer. I quite like your plan with the 3 floors. A few small things still, but we are currently trying to test a few different house placements on the property to get a better feeling. I will try to get back to you next week with new information and further ideas. I will pass on the argumentation as far as possible.

You can immediately notice how everything relaxes.

Where is the 2-meter mark under the roof for you? Are those the walls at 1.30? Or is it shallower?

The 2m line is marked and should be at about 2.85m. The knee wall with a height of 130 is at about 1.85m. Why do you ask? Did I miscalculate?

No, or rather no idea. I just want to understand your drawing and the measurements. Ultimately, there are none, and there is only a "1.30m" in some areas that can't be assigned. I know that your program also has its quirks just like my program, which I work with.

The 2m line is drawn in

are those the continuous lines then?

Yes, the solid line represents the 2m. The 130 is the [Drempelhöhe].
