ADAPTATIVE ARCHITECTURE
Bangladesh, vulnerable to climate change, faces severe impacts from sea level rise and extreme weather, causing mass migrations to Dhaka and overcrowded slums like Korail. A proposed solution is a market as a public space for community resilience, using adaptive, modular design and modern technologies to transform water from a vulnerability into a resource.

LOCATION: Korail Slum, Bangladesh
First map shows Bangladesh, followed by Dhaka, highlighting Korail Slum. Korail, on a peninsula in Gulshan Lake, is isolated by natural barriers and a wall from the colony. Surrounded by canals and affluent neighborhoods, residents rely on water transport. Illegal land occupation creates environmental and health issues, making it a dense, vulnerable space.
CONTEXT: Dwelling in Korail
The slum inhabitants live in fragile bamboo and tin homes, lacking private kitchens. There are three housing types: on the ground, partially on plinths, and entirely on plinths. The slum needs a catalyst for change, embracing Bangladeshi culture and unity. Active engagement from residents is essential for this transformation.
PROPOSAL: A New Market as a Catalyst
A market space was selected to drive transformation, providing Korail residents with a communal hub for economic and social growth as well as cultural exchange. This area doubles as a learning platform where residents participate in the construction and acquire skills to enhance slum safety and improve their homes post-market completion.
PROPOSAL: Organization
A central void makes water the focal point in a large square, turning it from vulnerability to a positive element. Roofs provide shade and collect drinking water. Entryways are placed on all four sides, linking the project to its context while suggesting ways of expanding, as the piers allow other systems to seamlessly plug-in.
PROPOSAL: Circulation
The main pathway encircles the central area, providing convenient access to all vendors. Secondary routes along the periphery enable visitors to explore the platform's edge and utilize spaces between stalls. This layout meets diverse vendor needs and enhances visitor experience, fostering a dynamic, inclusive marketplace environment.
PROPOSAL: Elevation
The new structure follows simple lines, making its construction simple enough for dwellers to partake, whilst creating a contrast with the lack of order in the existing fabric.
PROPOSAL: Vending Stalls
Experienced sellers rent enclosed stalls, while fixed bamboo platform furniture, available at lower rates, serves as comfortable item displays. The space between stalls encourages socializing and pausing.
PROPOSAL: Vending Space
The two large roofs extend over empty spaces, ideal for informal vendors to display goods transiently with towels or carts.
AXONOMETRY: Water Management
The large roof acts as a water collection system, gathering rainwater that is then filtered first through physical filtration and later through a UV filtration system that is powered by the solar panels displayed over the roof. These same panels provide the energy for the lighting system over night, ensuring that the space can be used at all hours.
MODEL: Bamboo sticks
The market's modular grid uses bamboo platforms with repurposed bottles for flotation, allowing vertical movement anchored by four pillars. These pillars support roofs with traditional joints and corrugated metal sheets, while stalls feature bamboo and repurposed materials with wattle and daub walls for resilience to water fluctuations.
