This "tube house ", designed by Indian architect Charles Correa, was first prize winner for low-cost housing organised by the Gujarat Housing Board. Though the programme specified walk-up apartments, these row-houses provided the same density and larger living space per family. The section is shaped so that the hot air rises and escapes form the top, setting up a convection currents of natural ventilation. Inside the units there are almost no doors; privacy being created by the various levels themselves, and security by the pergola-grid over the internal courtyard.
