It sounds like you need the whole wall taking down and any roots from that Buddleia completely removing. New footings will have to be dug to ensure the strength of the new wall. As for the bricks, they can be matched with what you have left from a reclamation supplier or the other alternative is to get new bricks that blend with the originals. Its a case of being able to source and availability. Post the job on Rated People and get a few quotes.
