It looks like the same street as Aunt Babe's House, not on Albert Square but in or near Walford I think. In reality Babe's House is 10 Welbeck Close, Borehamwood (Right by the EE Set). I'm thinking Claudette's in reality is 2 or 4 Welbeck Close, Borehamwood. I'm saying this because the view outside of Claudette's house is recognisable to that street. The only doubt about it is the door, but they could of had a new one in a year. Hope this helps!!
