I'm building a home studio myself (no previous construction experience) based on a design from a draftsman. I worked quite a bit out for myself, but I have a question about how to frame the eaves on a gable roof. From my research it seems there's no right or wrong answer, but I'd appreciate any thoughts or pointers,
This seems really complex in my head, so I'll provide pictures as a guide.
The studio's dimension are 5,000 x 3,000mm with the centre beam running from the mid point of 5m sides, so it will look like this:
The roof schedule calls for 140x45 rafters at 900 centres. So that's four rafters on each side. So far so good.
Now, my question is how do I get the overhang over the deck at the front and also at the back?
The eaves at front will be 750mm and at the back 450mm.
There are two primary ways which keep coming up in my research. The first is to cut a notch (or two, this is a long span) into the end rafter so a beam (don't knwo if this is the correct term) can sit flush to the outer roof level, like this:

The second approach is more involved and involves moving the rafters in a little and installing a verge plate and trimmers, like this:

Now, my question: my preference is the first approach, for ease and cost. However I could see how the second option would be more stable. So, people who know this stuff, whihc would you go with?
Thanks in advance.
