Of these two rafters only one is permanent and built into the shoulder of the gable. The rafter closest to Kieran will be removed later.
No stonework should protrude above the rafter edge and if stones don’t have a natural slope of their own, they need to be marked and trimmed to size.
A tiny square window in the gable end (measuring a foot) is now too low set in the wall, so we simply block it up and draw a new position immediately above the old one. The splayed shape towards the interior is for to exploit light.
