Series 10 Filming & Behind the Scenes

[langley]

Does anyone here know where that roof is? I am fully anticipating a Harry/Ruth kissing or at least hugging scene, and they wouldn't do it on the grid (not romantic enough and everyone could see) and not on the Thames with all the fans posting production pics on Twitter. So it has to be on that roof, and I want to go there and see if I can get a view of it from somewhere! (I mean if I win the lottery).
Of course I'd have to be there late at night. This scenario is getting more and more unlikely...
