I have a small problem with my ongoing extension. I will contact my designer to see what he had in mind, but I will see if there's someone here who might have a good idea.

If you look at the pictures, you see a somewhat tricky detail where a recessed terrace meets the rafters, the part I can't figure out is the "hammarbandet" or lejden. It should be 38x145 (I will use 45x150) but it's drawn as 38x85mm... a bit too weak. Is there something I'm missing (e.g., interpreting the drawing wrong)? In other words, how should one fit a 45x150..?

Detail where you can see the lejden more clearly.

Has the designer said it should be 45x150? If so, the drawing is probably not revised?
 
It should be 38x145 according to the text in the drawing. But he has drawn in a "38x85", and I don't understand how to fit a 38x145 or ideally a 45x150 there. Yes, the drawings have been ready for a long time, this detail was missed.
 
Can add that it is marked 38x145 everywhere except on this detail drawing.
 
Okay, the best thing is probably to check with the konstruktör :)
