Chennai, a historical seaside city on the southern coast of India, has undergone extensive urbanisation ever since the postcolonial economic reform of the nineties. Mismanaged urban growth that predominantly prioritises economic development has led to a situation of congestion, lack of public space and forgotten ecological networks in the city. These issues, over time, have amounted to a living environment that is negligent of the pedestrian, and lacks many opportunities for social interactions, opportunities to sit, walk or just wander in the city. The recently redefined building codes stand to further exacerbate the situation, due to the lack of an integrated perspective of densification in the city. This project aims to find potentials in the ever changing and densifying city, to facilitate liveable and vibrant environments for those who inhabit it. The process of densification and urban growth is redefined in Chennai, through the evaluation of its synergies and conflicts with the mobility network and the ecological systems in the city. This results in a trans-scalar design and planning strategy that facilitates urban transformation in a holistic manner, taking into account ecological impacts, mobility patterns and local daily use patterns of public space by the people in the city.

This project displays an explorative attempt at redefining the megablock planning concept. The Greater Bay Area (GBA), as the site of interest, is undergoing rapid metropolization, with a risk of resulting in the formation of indistinguishable, generic urban structures. The fast development and the migration process have defined a region with multiple identities and diverse groups of people living in it. The social and spatial implications of the metropolization process reflect a segregation between the actual planning system and the diverse people that live in this region. The proposal aims to transform the megablock, a traditional, structural form of planning that is a form of de-contextualized, top down planning based around an economic, private-driven market, into a planning tool that enables the cohabitation of multiple lifestyles that creates social networks of interaction, activates spaces of the existing context and relates them with new developments. Therefore, the redefining of the megablock intends to find how rapid urbanization and the enhancement of distinct local and external identities can go hand-in-hand in a multiplicity of urban contexts, creating a balance between quantity and quality and creating a process of place making that allows the enhancement and strengthening of the notion of identity in a local, urban and regional scale. The Megablock becomes a sustainable prototype for future urbanization and a morphological spatial structure that re-establish a spatial order and framework for the transitions and relations between diverse places and people.
