Terry Smith's work is highly site-specific, relying on a careful manipulation of the materials to hand in a given location. In one of his Site Unseen projects - a term he uses for his interventions - Smith transformed a South London house which was condemned to demolition into an installation piece by methodically stripping away surface elements to reveal the patterned structural layers beneath. For his most recent Site Unseen work he installed a number of photographic 'interruptions' in the Flaxmill in Shrewsbury, constructed in 1796 and the world's first iron-framed building. Since the mid-1990s Terry Smith has completed over sixty projects worldwide, most of which were site-specific works that were ultimately destroyed.
