I'm building a carport thing at the back and off to one side ofthe house. It's self supporting, basically two long beams on legs with rafters between them, then it's getting a 16mm uPVC roof on top.

The problem is that I've extended it 18" past the side of the house, to make it 'look right'. This leaves me with one rafter that meets the lower beam the same as all the others, but the high end will meet a brick wall instead of the higher beam. This rafter won't be taking much load at all, it's basically cosmetic.

I need a way to attach the high end to the wall. Usually I'd have either a wall plate or a joist hanger there, but this one will be highly visible and I'd like to get that 'it just carries on into the wall' look.

Can I just firmly fix the birdsmouth at the other end to stop it sliding outwards, then attach the top end straight into the wall with a few long multifix screws? Or if not, what would you all suggest?
