Casa Pia, a unique single-storey bungalow located in Hauz Khas, South Delhi, represents a blend of Chandigarh-inspired modernism and sustainable living. Designed by Indur Mirchandani in 1972, the house reflects principles of modernist functionalism and climate sensitivity, integrating 'Garden City' concepts with social infrastructure. Mirchandani, who previously worked with renowned architects like Le Corbusier, aimed to create a home that was not only aesthetically pleasing but also practical and cost-effective. The bungalow features a red brick exterior, ample ventilation, and energy-efficient design, allowing it to remain comfortable year-round without reliance on air conditioning. Despite the skyrocketing real estate prices in Delhi, the Mirchandani family has preserved the house's original structure for over 50 years, opting for minimal upgrades. This commitment to maintaining the bungalow highlights the importance of architectural heritage and sustainable living in a rapidly urbanizing environment.
