Critical regionalism is an architectural approach that seeks to correct sterile and abstract modernism by using contextual forces that focus on local needs and potential. As globalisation disrupts and displaces local building traditions in India's metropolitan cities, critical regionalism offers resistance to the homogenising forces of global modernism. This paper analyses five key architectural works realised in Delhi in the past four decades that incorporate the ideas of critical regionalism in their designs. The different approaches adopted by regionalist architects in dealing with local climate, topography, materials and sociological complexes have been presented. By limiting itself to regionalist works in Delhi, the paper attempts to highlight that critical regionalism is not a set of aesthetic preferences but a philosophical framework capable of producing diverse forms of architecture despite analogous external influences arising from similar site conditions.
