Abstract
The southwest coast of India, especially the Goa-Karwar region, is characterized by a unique architectural identity shaped by tropical climate, local resources, and the interaction of indigenous and colonial influences. This study examines the distinct architectural features and climatic adaptations of the area, focusing on visibility, place identity, and environmental responsiveness. Courtyard systems, central to traditional homes, act as natural ventilation zones and communal spaces, enhancing airflow, natural light, and social cohesion in hot, humid conditions. Additional architectural elements, such as deep balconies, brise-soleil, and wide verandahs, provide protection from intense sunlight and monsoon rains, enhancing visual identity and functionality. Local materials like laterite stone, cow dung plaster, wood, and Mangalore tiles are extensively used in construction, offering thermal insulation, durability, and sustainability. These materials and architectural forms create a lasting visual and cultural imprint on the environment. Sun shading devices—lattice screens (jails), large wooden windows, and ventilated roof spaces—improve airflow and reduce heat gain, addressing the region’s climatic demands while enhancing place identity. The architectural landscape reflects a harmonious blend of Portuguese colonial influences in Goa, characterized by vibrant facades, Baroque churches, and distinctive balconies, with traditional South Indian features in Karwar, such as sloped, terraced roofs and decorative joinery. The study underscores the importance of preserving these elements, as they contribute to a strong sense of place and attachment, embodying both the historical and cultural significance of the region amid modernization. Through this lens, the paper analyses how architectural forms and material choices contribute to a sustainable, unique architectural landscape in the Goa-Karwar region, balancing environmental harmony with cultural heritage.
