Hello everyone,
after reading through this forum a bit, I see that many of you have the necessary experience to provide valuable advice.
We plan to design our house with an architect, but some initial input wouldn’t hurt :-)
We do not want a prefabricated house.
Our half of the semi-detached house has a length of 12 meters (39 feet) and a width of 7.50 meters (25 feet).
We want to include a basement. The wall height is specified in the building plans as 6.20 meters (20 feet), and the ridge height as 8.25 meters (27 feet). The roof must have a pitch angle between 0 and 20 degrees. A maximum of two full stories are allowed.
Our dream is an open kitchen with dining and living areas (where the living area should be somewhat separated by a fireplace).
One bathroom on the ground floor, and possibly a small office.
If an attic level is possible, we would build two children’s bedrooms, a playroom, and a bathroom on the first floor.
In the attic, we would want the master bedroom, dressing room, bathroom, and possibly an office.
If an attic is not possible, then the master bedroom and dressing room would need to be included on the first floor.
Do the experts here know if an attic level is feasible or if this is impossible?
Which additional features would you consider indispensable or recommend?
Perhaps someone could even help us with a nice floor plan. :-)
Thank you very much in advance!

Is it actually sensible to have a building plan drawn up by a draftsman (without an architect, Either way: a draftsman is a sort of architectural assistant, and if you hardly know anything yourself, it is unlikely that you will get anything more (suitable) or individualized than what a standard catalog plan could offer. Apart from limitations due to dimensions and house shape, the selection of proposals is not that narrow either—semi-detached houses are currently very popular, so every provider has solid options.
In a development area like this, I would probably go with the other half of the semi-detached unit to a joint structural builder. One who also acts as a developer will likely already have suitable base designs in their portfolio.

Am I allowed to build a maximum of 2 full stories with 90m² (970 sq ft) of floor area each? Exactly. GF = floor area per story, given here as an absolute value and not related to the plot size by a floor area ratio, which is unusual but possible.

The building envelope for this plot is apparently strictly limited in width (7.50m (25 ft)) and indirectly limited in depth by the floor plan (a maximum of 90m² (970 sq ft)). The large section reveals what was hardly visible in the “small excerpt”: The building envelope is 7.5m by 12m (actually 11.99m), which corresponds to the maximum floor plan. With full utilization, fitting a garage and driveway will be very tight (max. 45m² (485 sq ft)).

since a roof terrace is also included. Why? Unless some other “small excerpts” are missing, the floor area is only calculated for all full stories. §20 Land Use Ordinance (3) The floor area is determined according to the exterior dimensions of the building on all full stories... (4)... ancillary structures as defined in §14, balconies, loggias, terraces ... are not considered. The height will likely be the limiting factor. With 8.25m (27 ft), each story can be at most 2.75m (9 ft) high. You will need a very slim floor construction.

By estimation, at 20 degrees on a 12-meter (39 feet) house / 6-meter (20 feet) midpoint with a height of 120cm (47 inches). Tangent alpha = opposite side / adjacent side = h / s
h = s * tan α = 6m (20 feet) * tan 20° = 2.18m (7.15 feet)
Combined with a knee wall left by the other floors of 6.20m (20.3 feet) wall height, this results in a nice attic studio (considering the full story height limits).
Just a quick question:
For a relatively narrow building of 7.50 meters (24.6 feet), I think a ceiling height of 2.60 meters (8.5 feet) is still reasonable. Could I calculate it like this:
Basement ceiling at 0
Room height 2.60 meters (8.5 feet)
Ceiling thickness about 0.30 meters (1 foot)
Upper floor 2.60 meters (8.5 feet)
Ceiling 0.30 meters (1 foot)
= 5.80 meters (19 feet)
8.25 meters (27 feet) ridge height – 5.80 meters (19 feet) = 2.45 meters (8 feet) room height in the attic. (Minus 15 cm (6 inches) roof insulation + 15 cm (6 inches) allowed tolerance = +/- 0)
That would mean an attic with 2.45 meters (8 feet) ceiling height at the highest point. A 40 cm (16 inches) knee wall seems possible because 6.20 meters (20.3 feet) – 5.80 meters (19 feet) = allowed wall height.
What do the tangent and the experts say about this? (I don’t have a calculator here)

Since a third “floor” is desired—for a parents’ area, that is—according to @Escrodas’s statement, a recessed top floor with a bedroom, walk-in closet, and a small shower room can be accommodated. The height regulations are somewhat flexible... I don’t see a problem there.
However, I believe that children don’t really need a dedicated playroom, not even in a house. What are the children’s bedrooms for, then? Is a toddler supposed to only sleep there? Well... to me, this just seems like an unnecessary expansion of the house, especially since there is also a basement, which will be equipped as an office but still offers additional space.
I would rather plan a utility room on the children’s floor and possibly move a hobby room for everyone down to the basement.
Anyway: now the two parties have to agree on the overall house design.
I’m willing to bet that you’ll have a few fewer friends after building the house 😉

My thought experiment regarding a recessed upper floor assumes making full use of the eaves height (which would probably yield less than half a meter (1.5 feet) of knee wall) and adding a mono-pitched roof.
Height tolerances here – as far as I have correctly understood – relate to the position of the reference point "top edge of the finished ground floor slab" relative to an absolute elevation benchmark for each plot. However, they do not apply, for example, to the ridge height above the ground floor level.
