I was delighted to see that splendid grandstander Max Hutchinson at the event. At first glance he seemed to be wearing an orange fright wig, but on closer examination this turned out to be a fetching new look (auburn) of the real thing. Max tells me he disapproves of the Stirling winner on the grounds that 'it is not a building. Buildings have toilets, the bridge has no toilet.' This unusual contribution to thinking about the nature of architectural form misses, surely, at least one relevant point: the bridge lifts in an arc not so dissimilar to the seat of a lavatory (as I prefer to call it).
