Eco-Brutalism: A Climate Responsive Approach to Architecture in India

The architectural paradigm of Brutalism, characterized by its raw aesthetic, monumental massing, and honest expression of materials—primarily reinforced concrete—has a profound and complex history in post-independence India. Originally symbolizing modernity, strength, and a break from colonial ornamentation, traditional Brutalism has faced contemporary scrutiny regarding its environmental footprint, particularly the high embodied carbon of cement and the thermal performance of exposed mass in tropical climates. This dissertation investigates the emergence of “Eco-Brutalism,” a critical evolution that harmonizes the structural robustness and material honesty of Brutalism with ecological sensitivity. By analysing functional strategies (passive cooling, thermal mass optimization), material innovations (Limestone Calcined Clay Cement – LC3, fly ash composites, basalt-concrete hybridization), and bio-climatic integration (living facades, modern jaalis), this research establishes Eco-Brutalism not merely as an aesthetic revival but as a viable, high-performance climate-responsive strategy for the Indian subcontinent. Through quantitative analysis of thermal performance, embodied energy comparisons, and detailed case studies ranging from the heritage of Le Corbusier and B.V. Doshi to contemporary residential innovations by Spasm Design and The Grid Architects, this report provides a comprehensive framework for implementing Eco-Brutalist principles in India’s diverse composite, hot-dry, and warm-humid climatic zones, with a specific implementation focus on the Chhattisgarh region.
