Hidden in plain sight, the Malabar Hill Forest Trail Project is a transformative initiative that brings together citizen-led vision, architectural sensitivity and sustainable construction to reclaim a forest stretch in the heart of Mumbai – without disturbing a single tree. Inaugurated on March 30, 2025, by Maharashtra Minister Mangal Prabhat Lodha, the project is the result of a unique collaboration between the Nepean Sea Road Citizens' Forum (NRCF), IMK Architects, the JSW Foundation, and the Brihanmumbai Municipal Corporation (BMC). This collaboration between citizens, architects, civic authorities and private partners sets a benchmark for sustainable urban conservation. A shared vision for conservation Early in the process, reaching a shared understanding among stakeholders – from civic bodies to community groups – was a crucial milestone. It was agreed that protecting the forest and reviving it sensitively was non-negotiable. The decision to elevate the trail on steel columns marked a turning point. It allowed public access while keeping the forest floor untouched, a principle that guided the entire project. “Elevating the trail would allow people to access and experience the forest without damaging it, setting the tone for everything that followed,” affirms Rahul Kadri, Partner and Principal Architect, IMK Architects. Navigating terrain and complexity The forest's condition – marked by eroded slopes, broken paths and encroachment – demanded careful, site-responsive planning. The terrain left little margin for error. Designing the elevated trail meant preserving every tree, accommodating uneven ground, and allowing rainwater and wildlife to move freely. The result is an undulating walkway that rises from 2 m to 10 m above the ground, adapting to the land’s natural contours while avoiding invasive construction. Sustainability in every step Sustainability lies at the heart of the project. Low-impact pile foundations were used to preserve root systems and natural drainage paths. Weathered Merbau wood was chosen for its resilience and ability to blend with the forest landscape, while epoxy-coated steel columns ensure long-term durability in coastal conditions. Lighting was kept minimal and integrated into the wooden balustrades using warm LED strips to avoid disturbing the forest’s rhythm after dark. “These structural, material and logistical choices were rooted in the larger aim of letting the forest breathe while opening it up safely for public engagement,” explains Kadri. Prefabrication and precision Given the ecological sensitivity of the site, a prefabricated construction approach was adopted. Major components were manufactured offsite, reducing on-ground activity and environmental disruption. Manual methods replaced heavy machinery, especially in steep or densely wooded areas. Detailed site mapping in the early planning stages enabled designers to route the trail through natural clearings and avoid disturbing water channels or tree formations. Regular coordination between the BMC, NRCF, JSW Foundation and IMK Architects ensured responsive, adaptive execution throughout the build. A blueprint for urban green projects The trail exemplifies a new model for city-led green interventions, one where nature isn’t sacrificed for development. It also creates opportunities for contractors, consultants and suppliers to specialise in nature-sensitive solutions: modular steel systems, sustainably sourced materials and low-impact foundation methods. “This project shows how collaboration between public agencies, citizen groups and private players can unlock new urban conservation models that other cities could adapt to reclaim and reimagine their ecological assets,” says Kadri. More than just a scenic walkway, the Malabar Hill Forest Trail is a shaded, tranquil escape for city dwellers and a statement in favour of ecological resilience. It offers a path forward – literally and symbolically – toward greener, more inclusive urban futures.
