Martin Pawley is incorrect in his assessment of the characteristics of Heathrow Airport as a city on one point (aj 7.5.98). It is, in fact, encumbered with at least one listed building. Technical Block A on British Airways' West Base was listed Grade II a couple of years back.
Designed by Sir E Owen Williams in the early 1950s to house boac in its entirety, the building has office space for up to 4000 people and four hangars, three of which hold one 747 and one Concorde side by side. I wonder whether this makes it the largest listed building in the country?
As giants go, therefore, the World Cargo Centre is in good company. As ba's town planning consultants, may we say to Tony Banks - don't ever list it! One listed giant at Heathrow is more than enough food for thought for ourselves and the local conservation officer.
