Ratish Nanda, who will be at The Hindu Lit For Life in Delhi, talks about the Urban Renewal Initiative. Ratish Nanda’s interest in conservation goes back nearly 25 years, to the first year of architecture school. For an urban history assignment, requiring the study of a historic settlement in Delhi, Nanda chose Kotla Mubarakpur. There he discovered centuries-old buildings which he had no idea existed. It brought home the importance of heritage, which Nanda has since worked towards conserving.
