Making shelter is a fundamental human activity, so, asks Former President of the Royal Institute of British Architects, Sunand Prasad - why don't we talk about it? The way we build reflects society's values and aspirations - but also its fears. Sunand Prasad takes us on a journey through Architecture,from the India he grew up in, to the Utopian vision of Le Corbusier, from the concrete carbuncles of Post-War Britain, to the design that will combat Climate Change.

In this fourth programme, Sunand takes us back to the place he grew up, Sevagram. Recalling the way of life of this community, founded by Gandhi, Sunand finds out what today's architects can learn from traditional ways of living. He also looks at the challenge architecture faces in creating zero-carbon buildings, and asks - in an age where air-conditioning and central heating are the norm, are we ready to make the changes to our buildings that will combat Climate Change, and so ensure the future of the World?
