P Aureosulcata is one of the more "inquisitive" Phyllostachys that you can grow in Britain, but, in British conditions it is not very invasive like some other bamboos you can grow here such as Sasa and Yushania spp. It is known to be really rather invasive in warmer climates, and you've been shown some pictures of what it can do in the south of France, but most places in Britain, it won't do that. Though if you are in a mild and damp part of Britain such as the south coast, it will be more invasive. Aureosulcata's general tendency is to send off one long rhizome in one direction, creating a long line of volunteers - you can see a photo of this in Paul Whitaker's book - not invade uncontrollably in all directions. So I expect that in practice, with plenty of space, you will be able to control it. Ideally one grows it surrounded by lawn and then the lawnmower will do most of what is needed. I've got a P. vivax aureocaulis, also a bit thuggish, I grow surrounded by lawn, and the lawn-mower keeps it in place.
