ᐅ Eaves height 3 meters: Is a 1.5-story single-family house possible with this?

We have 400 sqm (4,300 sq ft) available in one of our dream locations. About 250 sqm (2,690 sq ft) can be built on within the building boundary. I tried to illustrate this:
The development plan states:
Floor area ratio = 0.4, gable roof mandatory
If I understand the eaves height correctly, the roof must sit almost directly on top of the floor ceiling at a story height of 2.5 m (8 ft 2 in) to reach an eaves height of 3.0 m (9 ft 10 in). There can’t be more than about 30 cm (12 in) of knee wall, right?
Does this still allow for a 1.5-story single-family house? We would actually prefer one of the typical modular house designs with a maximum footprint of 8 x 10 m (26 x 33 ft) (located close to the street access, with a large garden on the west side). But how does this work regarding the attic under these conditions?
What do you think?
Best regards,
Jens

My last example calculation referred to your example of an 8 x 10m (26 x 33 ft) house, which would have just under 100 sqm (1,076 sq ft) of potential – but a larger house is also possible on the plot. However, it would clearly be only a one-and-a-half-story house, practically without knee walls.
If you wanted a townhouse, that wouldn’t work there.

Of course, an intelligent person knows – though unfortunately such a person doesn’t make regulations – that a knee wall is meant to avoid having a short sloped wall under the roof slope. Therefore, having a knee wall at (dachshund) knee height is complete nonsense. I cannot understand your criticism of the development plan. The city planners do not want a knee wall here, and there are certainly many prefab houses that easily comply with the requirements of the zoning plan. If the knee wall is that important to someone, they simply shouldn’t buy a plot here.

How much more would be possible? Maximum buildable area is 160. Garage, terrace, access path. So not much more is really possible. Well, 8m*10m is just 80m² (860 sq ft). Let’s take 9m*12m = 108m² (1160 sq ft) plus 30m² (320 sq ft) terrace makes 138m² (1.38 floor area ratio). Floor area ratio-2 would be 400m² (4,305 sq ft)*0.6 = 240m² (2,583 sq ft), leaving about 100m² (1,076 sq ft) for garage and driveway, which should be sufficient for a proper double garage.
First of all, I actually find this plot of land too small. When building a house, you want—or at least I do—a bit of privacy and not to live wall-to-wall like in a city center. That said, if the plot is 400 square meters (4,300 square feet), I would build on a maximum of 100 square meters (1,080 square feet), so a foundation slab about 11 by 9 meters (36 by 30 feet), but no larger, mainly for aesthetic reasons. With that size, we get a classic suburban house, and to gain some space upstairs, it’s best to have a dormer with a gable roof, if that is allowed. It could turn out quite nice. Karsten
