Balkrishna Vithaldas Doshi is a pioneering Indian architect known for applying modernist concepts to an Indian context in a sensitive way. Some of his notable works include the Amdavad ni Gufa underground art gallery in Ahmedabad, which resembles a natural cave with a mosaic tile roof and tree trunk columns. Sangath, his office in Ahmedabad, employs passive solar design principles like vaulted roofs, subterranean spaces, and indirect natural lighting to remain cool inside. Doshi's designs demonstrate his philosophy of combining influences from the past with a relationship to the present, grounded in strong foundations.
