Kim's Flat

Does anyone know where they filmed the exterior of Kim's flat? I assume the interior was a set. Thanks!

I found this movie very entertaining with some very touching moments. Rupert Graves makes a charming manchild (except when Paul was being a jerk). Steven Mackintosh is great, too and so versatile. He played a real creep in "A Dark Adapted Eye" and a scary drug kingpin in one of the Prime Suspect episodes (sorry, can't remember the name). They are great dramas; I highly recommend them both.
