ᐅ Roof design / Mandatory use of the second floor in buildings with two full stories

Hello,
Our development plan allows for 2 full stories with a pitched roof at an angle greater than 30°. We are currently considering the best way to utilize this space. We are certain that we want at least a knee wall height of 1.8m (6 feet) on the upper floor, but we are also open to building without a knee wall and having 2.5m (8 feet) ceiling heights instead. Since we are planning a basement, we don’t need to use the entire attic space for storage, which raises the question: What roof pitch and upper floor height make the most sense? Building unnecessarily high doesn’t make sense, nor does having a large unused attic area. Are there examples of how the roof could be designed architecturally to enhance the sense of space? Essentially, an open roof design to create a generous, spacious feeling?
How would you design the roof given the above conditions?
We would appreciate suggestions, preferably with pictures.
Next week we will visit the architect and will of course ask these questions, but having ideas beforehand would be even better.
Best regards

I think you still need to work on your room layout. Which rooms do you need, where do they have to be located (or can they be elsewhere), and how large should they be? Then you can look at how to distribute these rooms across the appropriate floors.
The basement is quite important to me because I need a workshop for my hobby. Therefore, plastering is not an option. One could consider changing the full basement into a partial basement. However, it is still under discussion whether the existing vaulted cellar should be preserved or not.
A basement is also considered a full floor if, on average, more than 1.40 meters (4.6 feet) of it protrudes above ground level.
Otherwise, you might consider designing the basement as a living floor in the case of a slope and direct access from the basement to the garden, possibly including a workshop as an auxiliary room.
If that is not desired, still plan the basement as a full floor—for example, an office in the basement—with the attic having a knee wall height of 1.80 meters (5.9 feet) and a roof pitch of 32 degrees. The attic will not count as a full floor, and little attic space will remain. At 32 degrees, it is also possible to partially open rooms at the gable end.
Best regards in short

The original poster asked about the roof pitch, and I simply recommended that they first consider the intended use and then determine the roof pitch.I agree with that, but unfortunately, anything below 30° (degrees) preferred by them would be excluded here by the local building regulations / planning permission. Only from 30° (degrees) upwards is allowed here—and in my opinion, that is roughly the upper limit for exposed roof eaves without making the rooms feel cramped.

Our development plan specifies 2 full stories with a pitched roof with a slope greater than 30° (86°F). Is the Roman numeral II enclosed in a circle?The plot is almost completely level, so there is no sloped terrain.
The vaulted cellar should initially be excluded from consideration, as I currently assume it will be removed. I just have it in the back of my mind and plan to discuss it with the architect at the next opportunity.
We do not want a raised ground floor (is that the correct term?) for various reasons.
That means the upper floor with a knee wall height of 1.80 m (5 ft 11 in) and partial opening of the roof would definitely be an option.
Yes, the Roman numeral II is enclosed in a circle.
