Thanks chaps

No it's not a brewery......................... ok, yes it is

Ah, it was actually the mention of the chimney that lead me: made me think of the old Romford Brewery (IIRC the home of John Bull) and the smell of the mash filling the air.... Now it's just another 'one-of-the-same' shopping centre. 
I thought about the John Bull brewery but I've gone for Truman's as it's chimney was, and still is, a land mark in Whitechapel.
Is it a traction engine factory?
Now there's a great idea (he said pencilling the project in for 2020).
And after that we get treated with a whole town shot?
That can be done.
