Bring the area down to what you are used to by sitting on deck chairs in your filthy front garden during summer months with your family and friends wearing vests or football shirts. Hang a cross of St George out of one of the windows and have lots of empty beer cans filling up your bin. Always have at least one white good item on full view outside the front door and buy yourself a an M reg cavalier or mondeo and park it outside your house but never, ever use it.
You'll be able to overlay your working class ideals onto your new lower middle class environment and be universally hated but secretly feared by your neighbours as the rough family down the road.
