[Strawbale] Green roofs on strawbale buildings

[zac solomons <zac.solomons@gmail...>]

Hello all

I am considering putting a green roof on my next straw bale building. I have heard of several people doing this, but am struggling to find good info about how to do it. I have built two smallish loadbearing sb buildings so far, both with lightweight roofs. My next project is an outdoor kitchen for a school and i am a bit nervous about putting a big heavy roof on it. Due to budget constraints i would prefer not to involve an architect. It will be a simple one storey box but i am worried about calculating loads. If there is no point loading, can strawbale walls simply be relied upon to hold up an extensive green roof? Is there any structural info for strawbale walls available?

I'm also looking for a good guide to installing a green roof: how to build an effective drainage system, best plants and substrates etc  

Hope someone can help

All the best
