Thanks Max and everyone else for your replies. No doubt it is a confusing picture. As i understand it the most likely problem is that your render will crack if it takes the load? It would be amazing if some big building/engineering company did exhaustive testing of different straw bale walls, then i could let go of the butterflies in my stomach. Still thinking of maybe going with a lightweight roof, despite ingenious design solutions like Max's i wonder if i am trying to fit a square peg in a round hole! <br>

Just a fast comment to add to all of the good Green Roof advices;<br>
<br>
We made a small 3 walled load bearing stage for a school in 2009 with<br>
green roof. The trick is that I used 4 columns of round straw bales on<br>
end as the 4 load bearing columns, which holds a bond gbeam; simply the<br>
edges of the roof frame. As the structure is quite open towards the<br>
front, and the roof leans towards the back, there's also 2 round wood<br>
oak poles holding the roof in the front of the stage.<br>
You can see it all on one of the many photo-comic manuals on our site;<br>
look under 'resources'.<br>
<br>
Cheers,<br>
