Colonial architecture stands as a visible testament to the dominance of imperial powers, symbolizing not only political control but also an imposition of spatial ideologies in distant lands (Boxer, 1969). However, the architectural forms introduced by colonial powers were not static replicas of European designs. Over time, they evolved in response to the unique cultural, social, economic, and environmental conditions of the colonies (Freire & Meneses, 2009). The urban settlements established by the Portuguese in Goa, India, offer a compelling case study of such architectural transformations. In these settlements, particularly those with layered histories and heritage value, architecture became a site of negotiation between imported forms and local traditions. As cities grow, there is an inherent tension between urbanization and the conservation of heritage, which embodies the identity and roots of a place (Hamzah, 2020).

Rua Abade Faria in Margao, Goa, a historically significant road exemplifies this tension. The settlement's architectural fabric, once predominantly residential and rich with heritage value, has undergone significant transformations, influenced by urban pressures and changing social needs. As cities like Margao grow and modernize, the challenge becomes how to retain the heritage values embedded in historical settlements while accommodating the pressures of urbanisation, commercialisation, and infrastructural change which have redefined its identity, eroding many of the spatial and material qualities that once defined its character. However, these changes are not merely losses; they are also adaptations, negotiations between heritage, function, and modernity and the nuances of everyday life.

This research builds upon my undergraduate dissertation titled In Between Heritage and Progress: Urban Morphology of a Historical Urban Settlement - A Case of Abade Faria Road, Margao, completed in 2021 at Goa College of Architecture, Goa, India. That study aimed to trace the physical transformation of Rua Abade Faria, a historically significant street in Goa’s commercial capital across time. As a street once lined with Indo-Portuguese residential buildings, Abade Faria Road has increasingly been subjected to commercialisation, infrastructural pressure, and unsystematic redevelopment. The earlier work focused on documenting these shifts through a morphological lens, tracing changes in street patterns, building typologies, and urban character. The current research extends that inquiry by shifting its focus, from observing what has changed, to asking why those changes happened, how they were shaped by local and colonial conditions, and what they mean in the broader context of Goan architectural identity and heritage today.
