Hi mate, thats is what i was looking for, suspened timber......its what the house has, air bricks etc, the cold water main runs in the back, i have power and data cables going to garden room at the back,
also suspended timber i can work with ( have experience with)
i had a different build up idea in mind
outer block that sips would sit on the inner skin that would have wall plate and joists to sit on.
thans for the info requarding the ewi, i have an architect coming over, but its good to know where i stand and what would need to be done.
cheers
mick
