Gillett Square in Hackney, east London, was derelict and underdeveloped for years until, in the 1990s, it became an experiment in urban regeneration. Dominoes, a new photography book, documents the unique and vibrant lives of those who spend time in and around a particular corner of the square, where dominoes are played and life can be precarious. Dominoes by Roland Ramanan is published by Dewi Lewis. All photographs: Roland Ramanan
