Paul Finch refers to a massive disservice to London and Londoners; How about the massive disservice to the rest of the country if Heathrow were to be shut down? Johnson, Moylan and Foster seem to think that only London matters, so perhaps it would be best if London were to be 'floated' as a separate city state, Singapore style, leaving the rest of Britain (including Scotland, to my mind) to pursue more balanced physical and economic development strategies.
I wonder how many people would guess 'its presence as a beach hut' (despite its location) in the face of such strong architectural references - which, to me, suggest some early Victorian public utility, probably a pumping station, and not a lighthouse (despite its location).
Comment on: Planning victory in Isle of Man for Foster Lomas
Great Britain needs its main hub airport shifted to the other side of London like it needs a hole in the head. This is not about Great Britain, and it's not even really about London - except in the sense that it greases the way for Boris to further his political ambitions by gaining election to a parliamentary constituency - Uxbridge & South Ruislip - that would be a much quieter place should Heathrow be removed. True, land would be released for more housing, with good transport connections, but the commercial development - and very substantial employment - created by Heathrow would all move out, shifting to the 'empty spaces' (green belt?) of Essex or Kent. The London urban splodge would expand massively to the east, mainly to the benefit of developers, builders, designers - and, of course, Boris.
It would fit IKEA's professed image of social enlightenment if they - and Sainsbury - funded the reconstruction of this pioneering building on another site. If it's too small for Sainsbury's full range this suggests to me that the client bungled the design brief, but I bet that the likes of Aldi or Lidl could find it eminently useful.
