Hello,
my first post in this forum, so first of all: hello everyone! I’m inexperienced, so please excuse me if I say or ask something silly.
We are currently planning the attic conversion of an old building (town villa, built in 1895). The stairwell has a "side wing" (only 2.10m deep (7 ft), 6.80m wide (22 ft)). Parts of the facade and stairwell are under historic preservation, but not the roof, which has already undergone several alterations (old dormers removed, roof windows installed).
The sloping roof starts above an 80cm knee wall (2.6 ft) on the second floor, where the actual apartment is to be created. The question is what can be done with the attic above. The ceiling height in the attic reaches 2.50m (8.2 ft) directly under the ridge, with a roof pitch of 45 degrees, so there isn’t much space.
The idea is to install a roof balcony. However, all the examples I’ve found online are built starting at the exterior wall. This is not possible here, as that wall is already one floor below. Carving the balcony in like a loggia would cost too much space. Is it possible to build a balcony “cantilevered,” that is, projecting beyond the existing roof (but not beyond the outer walls)?
The ideal would be a roof terrace in the corner between the "main roof" and the "side wing" of the stairwell.
I haven’t seen anything like this anywhere and I’m wondering about structural issues, roof framing, and so on…

I saw a skylight that can be unfolded into a mini balcony. The glazed lower part can be pushed forward, while the upper window opens upwards. This creates a balcony about 1 meter (3.3 feet) wide and approximately 50 cm (20 inches) deep extending out from the roof. I wonder if something like this is available in larger sizes?

As for beams and structural engineering, only a structural engineer or someone knowledgeable in this area can advise you. This forum is only somewhat suitable for that.
Another issue not to be underestimated is drainage.
