Hi
My family and I are about to move onto 5 acres with a shed. The shed is going to be added onto, Bathroom and screened in area, and I would like to do the walls with rendered straw I have Three questions.
Can the walls be rendered staright onto the concrete slab?
There are already wooden supports in what will be the screened area. Where the walls meet them should the straw contact them and render around the lot or should I try to leave them mostly exposed? They just seem to be branches without any treatment at all.
Are there any problems with walling around the steel supports in what will be the bathroom?
I am worried about rotting the wood and a reaction with the steel and the wet concrete. I do not have much experience in building.
Help with these questions would be wonderful.

PS Is there anyone out there living the permaculture life in the Whitsundays?
