Does anyone have experience with, or thoughts on, how to construct a so-called cross roof on top of a lower floor?

3D illustration of a cross gable roof design, showing intersecting gables on a rectangular building, related to architectural construction discussion.

I have seen turn-of-the-century houses built this way and am interested in building a new one in the same style.

Question: How do you construct the roof solution itself? Are roof trusses used as in a traditional gable roof, which are then "cut" and built on with the projecting parts? The height of the roof is about 5 meters from the eaves, so we're talking about a relatively large construction.

Note! The question concerns the construction solution and not whether this house may be built within the local plan in Sweden due to current planning and building regulations, etc.

I think you made a mistake here. A house with such a roof essentially has the same building height as ridge height. A protrusion is included in the building height unless expressly exempted in the zoning plan.

Need to edit myself a bit here. If it is classified as smaller, it is not included. Maybe it can be in this case?

You are right. I correct my question text above. This question is completely independent of building permits and building height. I realize these are separate limitations, etc., but for the moment, I do not want to consider such possible restrictions. (In my case, I get around it).
 
We have longitudinal beams at the ridge where the roof truss legs rest (with columns for the beams) for both the main roof and the pediments, along with a cast floor slab that absorbs the tensile forces. It shouldn't be difficult for an engineer to come up with a solution given the conditions you have in mind.
