Different types of roof overhangs

Hello everyone,

I have a question about roof overhangs, especially with hip or pyramid roofs.
A bit about me: I am a layperson and am basically just starting out with the topic of new construction planning. Currently, after a discussion here in the forum, I am occupied with the roof.

When googling, I found two different forms of roof overhangs.
1) With hip or pyramid roofs, the overhang often appears to extend horizontally beyond the foundation walls:


2) With gable roofs, the roof eaves always slope further down beyond the foundation walls:


Do these different forms of roof overhangs have specific names? I have not been able to find anything about that so far.

The question came up because I had planned an overhang so that the roof would basically start with its slope there (like in the first picture, only with a steeper pitch). The roof is therefore about 1 meter wider than the foundation walls on all sides and rises evenly from there up to the peak. I wanted to first know if that is a common form of roof, meaning if it is basically feasible without major complications.
Or is the "trick" simply that in the first picture the foundation walls extend higher under the roof (like in the second picture), but you don’t see it because it is clad? Then it would simply be a knee wall with cladding.

Hi I am not a carpenter, but after a brief research I could imagine that in variant 1) roof trusses were used. The attic space is only conditionally usable. We have it too, as storage space it is OK. If 1) is a different roof structure than roof trusses, in my opinion a knee wall would have to be present. Variant 2) is then probably a purlin roof.
