Hello everyone!
A few questions about an attic studio with a low ridge height:
1) Is it possible to have a 2.5-story gable roof semi-detached house with a maximum ridge height of 9.00 m (29.5 ft), a house length of 10–11 meters (33–36 ft), and an eave height of up to 6.50 m (21 ft), including an attic studio? Or would it be better to plan a 2-story house without an attic studio?
2) With this ridge height, is a dormer or cross-gable feasible?
3) Would anyone possibly have a cross-section of such a house? (See attachment)
Best regards
Peter

I wouldn’t exactly call a ridge height of 9.00 m (29.5 ft) low…
First of all, according to building regulations, there is no such thing as a 2.5-story building type, only single-story, two-story, or multi-story classifications exist.
Your question cannot be fully answered without knowing the reference point for measuring the ridge height. Is it measured from the top edge of the finished floor or from the existing ground level? From the sectional drawing you attached, it appears that a usable attic space could be possible. However, the roof pitch also plays an important role here.
This primarily depends not on the eave or ridge height, but on the local zoning plan / building permit conditions.

Thanks for the response, building expert!
For a semi-detached house, I find a ridge height of 9.00 m (30 ft) to be quite low.
The reference point is the middle of the street at the center of the plot.
A dormer probably won’t work because the dormer ridge must be at least 50 cm (20 inches) lower than the main roof ridge, and the dormer roof will have a pitch of at least 10 degrees, so the dormer roof would end up too low.
For a house measuring 10 m x 7.50 m (33 ft x 25 ft), I calculate a roof pitch of 26.5°. With knee walls 1.40 m (4 ft 7 inches) high, I get an attic studio that can be divided into two rooms of 15 sqm (161 sq ft) each.
Let’s see what the construction company says about whether my calculations are roughly correct.
