Not my website; just a project I've helped out on.

I can't give a definitive answer to this, since I've not spoken to the owner about it, and 
have not seen first hand the roof details. 

But I do know he is planning to use a clay mix for the render, because the ground 
around the build is full of it. The roof is to be a turf roof (hence the engineered joists), 
and should have a substantial overhang all round. I suspect he will render to the top 
of the straw, up to the roofplate, but I would think rendering over the timber would be 
less successful. With a big enough roof overhang, it should not be possible for water 
ingress to occur at that point.
