What a view. What a guest list. What a party. The RIBA’s London Region has surely seen nothing like this before. The chairman’s annual dinner last night was held in the extraordinary surroundings of the Gherkin nosecone. As one wag put it, looking at the reflections of the bald heads in the glass and steel above, ‘the domes in the dome’. All the big names were there. Not just the usual RIBA faces – Andrew Hanson, Sunand Prasad, Jack Pringle et al – but the likes of architecture minister David Lammy, Tate boss Nick Serota and a smattering of London politicians, such as Nikki Gavron and Rikki Burdett.
