In February 2001 Michael Landy destroyed all his possessions. Every single one. This act of annihilation, entitled Break Down, took fourteen days to complete and cost approximately ?100,000….Landy spent three years cataloguing the 7,006 separate items. Each object was numbered, separated into a category and included in a long list displayed on the walls. The smaller objects were bagged in plastic and placed in yellow crates that snaked along 160 metres of conveyor belt around four dismantling bays. Landy and his team of operators, all clothed in industrial blue overalls, systematically reduced each item down to its basic components. The pieces were then shredded or granulated and bagged up.

The happiest day of my life
