Hello, we are planning our house, which we want to share with my mother (separate apartment approximately 70 sqm (750 sq ft)). We want to maximize the floor area with 137 sqm (1,475 sq ft). Maybe someone has ideas, suggestions, or improvements. We are grateful for any input.

One question is about the maximum building volume Of course, many parameters affect this. Based on the design, which uses the full footprint of 10.50m (34.4 feet) by 13.10m (43.0 feet), a knee wall height of approximately 1.80m (5.9 feet) would be possible.

whether Katja’s proposal of having the children’s rooms in the attic would fail because that would count as a third floor. Yes. You are absolutely right about that.
Hi,
I only saw this thread today and also did a quick sketch.
The office would then be located in the attic space, with a knee wall height of 115 centimeters (45 inches) and a roof pitch of 50 to 55 degrees, which keeps the building just under 9 meters (30 feet) in height.
However, I’m not entirely sure if this meets the regulations for full storeys in Brandenburg.
