I missed the Architecture Foundation’s tour of 469, Bethnal Green Road, a project by Carmody Groarke who are interesting architects (long ago, before the Olympics, they designed a restaurant on the roof of Westfield Stratford City).  It would be easy not to spot the project altogether because it is an adaptation of an existing building – adding three storeys made of galvanised metal on top of an existing, previously nondescript 1970s workshop.  It’s interesting to see architects (and developers) embracing the challenge of refurbishment in place of demolition and the fact that it fits so well in its surroundings is to its credit:-
