Rogers has devoted much of his later career to wider issues surrounding architecture, urbanism, sustainability and the ways in which cities are used. One early illustration of his thinking was an exhibition at the Royal Academy in 1986, entitled ""London As It Could Be"", which also featured the work of James Stirling and Rogers' former partner Norman Foster. This exhibition made public a series of proposals for transforming a large area of central London, subsequently dismissed as impractical by the city's authorities.
