Different roof overhang designs – what are the designations?
I have a question about roof overhangs, especially for hip or hipped roofs.
By googling, I found two different forms of roof overhangs.
1) In the case of hip or hipped roofs, the overhangs often extend horizontally beyond the foundation walls.

2) On gable roofs, the roof overhang always rolls further beyond the foundation walls (photo2)
Do these different forms of roof projection have their own designations?
The question arose because I had previously planned with an overhang, from which I wanted the roof to start, so to speak, with a slope (like in the first picture, only with a steeper slope). This way the roof is about 1 meter wider than the foundation walls on all sides and rises evenly from them to the top. First of all, I wanted to know whether this form of roof is normal, i.e. whether it can be realized in principle without any special contrivances.
Or is the "tricky part" that in the first picture the foundation walls go under the roof just as high (as in the second picture), only you don't see that because it is boarded up? Then it would just be a lap floor with cladding.
Answer
I daresay the first version used roof trusses. The attic space is of limited use in this case. We have one too, it is good as storage space.
If the first is a roof structure other than the roof trusses, there should be a knee-high floor.
Option number two is probably the roof purlins.
