It's going underneath an existing glass roof and is completely internal, so the lower plate is fixed to the internal wall.Another birdsmouth, just like the top. Then continue it down to a plumb (vertical) cut where the fascia’s going to be. Sometimes it needs another little notch further down to clear the outer skin (if there is one)
Edit: although your pic seems to suggest it abuts a wall at the bottom, like a lean to between two buildings. If so, you’ll need to get the gutter right…
Don't suppose you could do a quick drawing of what you mean if you don't mind.Normally the rafter would be seated with a birdsmouth, but if you did not want to see the ledger plate, just the underside of the ceiling meeting the wall, then you would use a 2x2 and a 2" notch on the bottom of the rafters.
Thanks. Is the 2x2 instead of the ledger plate or fixed to it to bring it out?
I'd put the lump at the bottom. That'll be a pig to cut out.
Ditto!Instead of. If you don't like it, put a ledger and joist hangers so the ledger is entirely in the ceiling
ps; think I'd have drawn that 2x2 a bit closer to the bottom of the rafter. In that location it's a bit weak
Would this work but the joist going upwards instead?Ditto!
Yes, as long as the thrust is taken into account.Would this work but the joist going upwards instead?

Didn't I mention truss clips?Would this work but the joist going upwards instead?
