I need to attached my ground level timber frame for decking to a sloped wall. How would i do this without making contact and the timber rotting from the rain?

Why do you feel the need to attach to wall?

well i thought because it was solid and i cant put posts into the ground as its massive rocks underneath rather than soil. I am unable to dig down to install the posts...

Install on top of pavement slabs (Cemented in)at corners and centrally, the shear weight requires no fixing to wall .
