ᐅ Build a house with a knee wall of 75 cm (30 inches) or two full stories? Your opinion?

Hello,
according to the building plan, we are allowed to build either a house with a knee wall up to 75cm (30 inches) or two full stories.
Therefore, we are currently considering the following two options.

- House with a 75cm (30 inches) knee wall, a 45-degree roof pitch, and a dormer with a flat roof
- House with two full stories, a gable roof with approximately 22-degree roof pitch

We are building without a basement and therefore rely on storage space in the attic. For this reason, a Tuscan-style house is probably out of the question.

I won’t go into our pros and cons here, as I’d like to hear your opinions first.

Oh, and since we plan a utility room and an office on the ground floor, there will be no space issues upstairs in either option.

Good luck and thanks in advance!

How old is the development plan? The term "full storey" was abolished in Bavaria eleven years ago. If the development plan is more recent and specifies a maximum of two storeys, the attic must not be large enough to allow for habitable rooms.

A roof pitch of 22° also means that a standing height of 2 meters (6.6 feet) is practically not achievable, not even directly in the center. Here is a sketch, assuming a house width of about 9 meters (30 feet) and a roof pitch of 22°. This is all without considering roof beams, insulation, and so on. I estimate a maximum height of 180 cm (5 feet 11 inches) exactly in the middle.

The development plan is brand new. The new housing area is currently being developed.
We are looking at about 1.8 meters (5 ft 11 in) ceiling height in the attic. [emoji846]
Our maximum ridge height is 9 meters (29 ft 6 in).

The attic will be used for typical storage like Christmas decorations, various moving boxes, etc.

But only at the very top, it quickly slopes down steeply to the right and left. The question is what you want to store there, and whether you plan to access it with a regular staircase or a retractable attic ladder. How tall are you? If you’re close to 180 cm (5 ft 11 in), it can become quite inconvenient storage space.

By the way, I think it would be helpful if you shared your pros and cons lists here. That way, others who think like you don’t have to repeat the same points but can simply agree or offer counterarguments. That’s much more productive. Otherwise, it just ends up being a survey of everyone’s preferences. Also, please include information about what you want to store there, or it will become even more arbitrary.

As I mentioned, in Bavaria there are no longer any full storeys in the attic. If the development plan allows a maximum of two storeys, option 1 could be disallowed because depending on the floor plan design, the attic might count as a third storey. To clarify this, you would need to provide more information, such as an excerpt from the development plan, textual regulations, and building dimensions.

If you are only looking for aesthetic opinions, I’m out.
