As a pioneer of low-cost housing and a former chairman of the National Commission on Urbanisation, Charles Correa has throughout his long career stressed the crucial relationship between affordable housing, public transport and job location. In the early 1960s, Correa, along with two other colleagues, actively championed this idea and proposed a radical restructuring of Mumbai (then known as Bombay) to deal with the city’s growing informal settlements. Their vision, now known as Navi Mumbai (New Bombay), was designed to accommodate 2 million people by developing land across the harbour that would change the pattern of growth in the city from a monocentric north-south one to a polycentric urban system around the bay. While Navi Mumbai remains one of the key large-scale urban planning projects of the last century, it is also the location for another important experiment of a smaller scale: Correa’s famous Belapur incremental housing project of 1983.
