    Construction of bricking external doorway

    thanks skimmers, its not a cavity wall. Just a double brick wall. I will try to tie in the DPC to the existing if there isn't any under the door frame. I think the major point is that you have to match or better the existing wall/ insulation? Thanks for the hardwall and waterproofer tip.

Just continue the wall another 1.4m on the fence side and break into the wall or use a wall starter next to the door. So there would be no walls...
