Now, somebody tell me why there's a factory in Croydon with a number

It's not a binary number, it's an arrangement of skylights. The southern
number alternates 1s and 0s, and the northern one nearly does, which
suggests that the similarity to ones and zeroes is coincidental. If you look
at the building further north, it has similar skylights but in a less
interesting pattern.


I concur - there's no secret code there. No move along please, these
ladies gentlemen from GCHQ wish to get on with their work in peace.
