Astragal had the pleasure of attending a seminar on tall buildings last week, which saw Uruguay’s favourite architectural son, Rafael Viñoly, give the audience the inside track on his latest ‘masterpiece’: the Walkie Talkie tower. As time began to run out, Viñoly was given the two minute signal, prompting him to skip through his work. ‘Boring’, he said, as slide after slide flicked up of his proposals for 20 Fenchurch Street. ‘Boring... boring’, he continued, until finally he reached his last slide, when he thanked his audience for listening. Boring, Rafael? Well, Astragal can certainly think of a few other words to describe that particular building.
