O'Donnell and Tuomey's transformation of Letterfrack Industrial School was the Irish entry at this year's Venice Biennale, which opened last Friday. Exhibiting architecture has never been easy. Showing it on a world stage, such as the Venice Biennale, represents an even bigger challenge; it simply can't be done effectively by pinning drawings to a wall and placing a model of the project out front. You also have to get with the theme, which this year's curator, Swiss-born architect Prof Kurt Forster, designated as metamorphosis, trendily shortened to "Metamorph". So what better project to represent Ireland than O'Donnell and Tuomey's transformation of Letterfrack Industrial School? The partly-realised plan to turn it into a furniture college was chosen by Shane O'Toole, Irish commissioner for this year's biennale, because he was struck by the fact that "some buildings have savage histories that can leave a place in need of a kind of architectural exorcism, a project of redemption".
