We are going to be upgrading an existing out building which is sigle skin (brick rendered) the existing walls have to stay and be insulated internally i was thinking of using rigid insulation with plasterboard attached.
The existing flat roof is to be replaced including joists and we are going to raise the walls by 400-500mm to acheive the required head room internally, our architect has specified light weight 100mm block so as not to place to much additional weight on the existing foundations and for ease but are we going to be able to fix masonary hangers from light weight block especially if the hangers are not in a mortar joint?
The foot print of the building is appx 3mX9m.
