Detached house ~ 150 sqm for 5 people

What are the requirements in the development plan regarding eaves height, roof slopes, number of floors, etc.? If you have the option, I would recommend a knee wall of 1.30m. That is a pleasing size to comfortably place a bed under the slope and not to perceive the room as too small. It would also be an advantage for the roof peak.

Something like this:

WOW thank you very much. I will definitely bring up this idea for discussion tonight. Thank you very, very much.

What are the regulations in the development plan regarding eave height, roof slopes, number of floors, etc.? If you have the option, I would recommend a knee wall of 1.30m. That is a pleasing size to comfortably place a bed under the slope and not feel the room is too small. It would also be an advantage for the roof peak.

The development plan only says that a maximum of 2 full floors are allowed, as well as a gable or hip roof. Otherwise, we have no regulations. Isn’t a knee wall of 1.30m already quite high? Then the window sills are also that high, right?

Isn't a knee wall of 1.30 already very high? Then the window sills must be that high too, right?

It is a good height to also place a bed under the slope. Or a chest of drawers. It has nothing to do with the windows.

Is a knee wall of 1.30 not already very high? Then the window sills must be that high too, right?

Window sills? Under the sloping roof?
Perhaps I haven't fully understood the project yet. What exactly is supposed to go into the upper floor on the south side as windows? No double casement windows? A view would be very enlightening.

For me, it looks roughly like this so far:

But I haven't quite finished with the east side yet...

It is a good height to also place a bed under the sloped ceiling. Or a dresser. It has nothing to do with windows.

Well, we have 2 large dormers with windows. It will shift it upwards if I raise the knee wall, won't it? View is coming.

From my own experience, because we moved into 140sqm (net living area without office and large corridors) + 70sqm basement 2 weeks ago, you have too little usable space in the house for 5 people. We also have 4 bedrooms upstairs in case a 3rd child comes. The living space is also borderline. For 5 people, if you subtract the utility room and office, you have 130sqm left. At the moment, I find the 140sqm with 2 children on the ground floor and upper floor really comfortable, but with a 3rd child it should not be less. If a 3rd child should really come, I would recommend building a bit larger.
