Introduction:

At 1965 British American Tobacco Bangladesh has been establish at Mohakhali DOHS, Dhaka – a secure, organized, and prestigious neighborhood within the capital city. The office is situated along New DOHS Road, offering convenient access via the Mohakhali Flyover and surrounded by important areas like Gulshan and Banani.

The premises reflect a modern corporate environment with a focus on sustainability, innovation, and professionalism. They are committed to minimizing the environmental impact caused by its operations and the tobacco industry, actively investing in sustainable practices, waste reduction, and eco-friendly technologies.

Site Analysis

Its location within Mohakhali DOHS, near green urban areas like Banani and Gulshan, offered a hidden opportunity to reconnect with the city’s broader ecological network. The site, part of a modern corporate campus, had suffered decades of decline—a lifeless, unpaved access route and informal dumping ground plagued by waterlogging, pest infestations, and the allelopathic effects of Mahogany trees that stifled biodiversity. Proximity to tobacco operations further degraded air and soil quality.

Employees endured a daily walk through this degraded landscape, disconnected from nature and emotionally taxing. Yet, beneath the decay lay potential: over time, the neglected land had begun regenerating itself, forming micro-ecosystems where resilient species adapted to the harsh conditions.

The design process began with deep observation and respect for this existing narrative. Rather than imposing external ideas or erasing the site’s past, the

team listened—to the soil, the trees, the water, and human experience. The site’s complexity became the foundation of its transformation, guiding a solution that emerged naturally and contextually.

Architectural Concept and Detail This project transforms a neglected 60-year-old industrial dumping ground into an ecologically responsive, socially inclusive garden. Rather than erase its past, the design builds upon the site’s history through minimal intervention, adaptive reuse, and preservation of naturally formed ecosystems. Invasive species were removed, while native, shade-tolerant vegetation was introduced to enhance biodiversity. Chronic waterlogging was resolved using passive systems—retention ponds, shallow gutters, and permeable surfaces—eliminating the need for costly infrastructure. Pedestrian paths followed natural contours, minimizing earthwork and preserving topography.

Areas of Innovation

This project introduced a range of innovations to address ecological, functional, and budgetary challenges while demonstrating how thoughtful design can regenerate even the most degraded sites.

Ecological Retention & Rehabilitation: The site had naturally evolved into a rare micro-ecosystem over decades of neglect. Rather than clearing this growth, the design embraced and preserved these biological patterns, building ecological resilience from within.

Water-Sensitive Urban Design (WSUD): To combat chronic waterlogging, the design worked with the site’s natural topography. Pith lines, shallow channels, and a retention pond were introduced to manage stormwater, passively irrigate vegetation, and enhance microclimate cooling—all without alienating users from the ground.

Strategic Planting under Mahogany Canopy: The dense, allelopathic Mahogany trees created chemically stressful, shaded conditions. The design introduced shade-tolerant, native species that could thrive in these challenging environments while enriching biodiversity and restoring soil health.

Scrapyard to Sanctuary: What was once an uninviting, polluted access route became a therapeutic walking garden, offering moments of calm, reflection, and sensory engagement for daily users.

Budget-Conscious Innovation: The project was achieved on a minimal budget through local materials, reuse of site elements, and low-maintenance design solutions—demonstrating that true innovation does not require excessive expenditure but sensitivity and creativity.

Innovative Project Technology

The project integrates site-responsive technologies with sustainable landscape practices, illustrating how low-tech, adaptive systems can outperform high-cost interventions.

Adaptive Reuse: The design transformed the 60-year-old dumping ground using adaptive reuse strategies. Existing site features—soil mounds, scrap concrete, mature trees—were retained and reprogrammed as ecological assets. This approach reduced construction waste, embodied energy, and carbon footprint.

Passive Hydrological Infrastructure: Chronic waterlogging was addressed with bio-retention ponds, natural percolation beds, and shallow infiltration trenches. These passive systems manage runoff, filter pollutants through layered soils and vegetation, and recharge groundwater without the need for mechanical drainage infrastructure.

Phytotechnology for Soil Remediation: The allelopathic impact of Mahogany trees had left soils chemically stressed. Phytoremediation

introduced native, nitrogen-fixing and ground-cover species that detoxify soils, enhance microbial activity, and promote healthier ecological function over time.

Biophilic Infrastructure Integration: Hardscape elements were designed to work with nature rather than against it. Modular concrete paths were laid to avoid root damage. Handrails double as benches, enhancing user comfort while fostering interaction with the landscape.

Ecological Zoning & Microclimate Engineering: The planting design strategically zoned shade-loving species under canopies and light-tolerant species near open areas and water bodies, creating thermally diverse zones that support biodiversity, passive cooling, and human comfort.

Material Loop & Soft Mobility: Vehicular routes were restructured to prioritize pedestrian pathways. Existing concrete was crushed and reused as sub-base, reducing material transport and supporting a closed-loop, low-energy construction cycle.

Together, these strategies offer a replicable model of adaptive landscape technology for urban and industrial regeneration—where deep ecological awareness and contextual design create resilient, high-value spaces without reliance on high-cost infrastructure.

Significance of the Project

This project stands as a model for ecological urban renewal, demonstrating how even the most neglected, polluted, and functionally obsolete urban spaces can be reclaimed, revitalized, and reimagined as thriving green sanctuaries. In an era where rapid urbanization often comes at the cost of ecological balance, this intervention offers a contrasting, hopeful vision: architecture as a tool for restoration rather than consumption. The former dumping ground—once a scar on the urban fabric and a symbol of

environmental degradation—has been transformed into a living system that filters air, harvests rainwater, cools the microclimate, fosters biodiversity, and enhances human well-being. In doing so, the project challenges conventional notions of architectural significance. Here, plants, water, soil, and native species are given equal importance to build form, proving that the most meaningful design can emerge from deep ecological sensitivity and humility toward the land. This transformation sets a replicable precedent for sustainable urban regeneration across the Global South and beyond.

Sustainable Architecture

Sustainability in this project is not an added layer, but the guiding principle behind every decision. Rather than imposing new structures, the design worked with the existing topography and ecology, embracing natural processes and systems. Chronic waterlogging—a persistent problem for decades—was resolved through nature-based solutions such as retention ponds, shallow drainage channels, and permeable surfaces that allow rainwater to percolate naturally. These passive systems support biodiversity, reduce heat stress, and eliminate reliance on artificial drainage infrastructure. Sensitive planting strategies responded to the site’s complex conditions, particularly under the dense, allelopathic Mahogany canopy. Resilient native species, including shade-tolerant ground covers and nitrogen-fixing plants, were introduced to detoxify soils, support pollinators, and enhance biodiversity without disrupting the natural rhythm of the land. The minimal-intervention approach preserved existing topography, reused materials, and avoided unnecessary earthworks, dramatically reducing the project’s carbon footprint. The result is a low-maintenance, regenerative landscape that functions as a living system—restoring ecological functions, improving microclimate, and offering resilience to urban environmental pressures.

Socially Responsible Architecture

At its core, this project reflects a deep sense of responsibility toward people, place, and planet. Situated within the grounds of a tobacco company—a product globally associated with public health and environmental harm—the project presented a unique ethical and ecological challenge. Transforming this neglected dumping ground into a green, biodiverse ecosystem offers both ecological restoration and symbolic reparation. The site now functions as a living filter—purifying air, supporting biodiversity, and nurturing mental well-being. Socially, the garden is inclusive, accessible, and human-centered. It was never intended as a decorative corporate gesture, but as a walkable, therapeutic space woven into the daily lives of employees. What was once a demoralizing, lifeless corridor is now a nature-infused transition that provides moments of reflection, calm, and connection at the start and end of the workday. The intervention redefines the role of corporate campuses in urban life, positioning them as stewards of the city’s ecological and social health. Through thoughtful design, companies can contribute tangible value not only through policy, but through place-making that benefits the broader community.

User Response

The impact of this transformation on daily experience has been profound. Where employees once walked through a hostile, polluted corridor, they now move through a living landscape—enveloped by greenery, birdsong, and cooling breezes. The space functions as a sensory-rich journey and mental refuge, subtly improving morale, focus, and well-being. Beyond human users, the garden has been embraced by wildlife: insects, butterflies, birds, and small animals have reclaimed the site, turning it into a vital node

within the city’s biodiversity network. Employees witness these natural moments—dragonflies hovering over water, birds nesting in trees—and are reminded daily that the space is alive and dynamic. This garden has become a symbol of resilience, coexistence, and care. It challenges the idea of corporate spaces as isolated zones of productivity, instead offering an inclusive, adaptive sanctuary shared by people and nature alike. The project powerfully illustrates how architecture, when rooted in empathy and ecological intelligence, can transform everyday experiences into rituals of connection and renewal.

Project Economy:

This project was completed on a minimal budget, emphasizing sustainability, adaptive reuse, and low-maintenance solutions. Initially estimated at over $327,880.00, the cost was significantly reduced to $184,432.50 through sustainable design decisions. By reusing existing site elements—such as preserved trees, recycled materials, and the natural terrain—the project minimized the need for extensive new construction or imported resources. Locally sourced materials and passive water management systems also helped control expenses while ensuring long-term resilience. The outcome demonstrates that meaningful ecological transformation doesn’t require excess—it thrives on contextual sensitivity, resourcefulness, and design intelligence.

Abstract

This project reimagines a 60-year-old industrial dumping ground within a tobacco company compound into a vibrant, ecologically responsive urban garden. Located in Dhaka’s Mohakhali DOHS, the site—once marked by environmental degradation, waterlogging, and toxic soil conditions—has been transformed through a context-sensitive, regenerative design approach. Rather than erasing its troubled past, the intervention embraces the site’s history and latent ecological potential, using minimal intervention, adaptive reuse, and water-sensitive urban design.

Key strategies included preserving naturally emerging micro-ecosystems, phytoremediation to detoxify allelopathic soil, and passive hydrological systems such as retention ponds and permeable surfaces to mitigate chronic flooding. Shade-tolerant native vegetation was introduced to enhance biodiversity under dense Mahogany canopies, while modular, biophilic infrastructure supports user comfort and ecological continuity. The project also demonstrates soft mobility and closed-loop material cycles, reusing onsite concrete and minimizing the carbon footprint.

This low-cost transformation has significantly improved the quality of everyday experiences for employees, turning a once lifeless passage into a sensory-rich, therapeutic landscape. The garden now serves not only as a space of physical transition but as a mental refuge—fostering environmental awareness, well-being, and a sense of shared stewardship. Birds, insects, and small wildlife have returned, reinforcing the site’s role as a node within the city’s ecological network.

Beyond its physical form, the project is a powerful example of socially responsible design within a corporate context. It symbolizes ecological reconciliation, healing, and coexistence—offering a replicable model for sustainable land reuse across rapidly urbanizing regions. In doing so, it redefines corporate architecture as a vehicle for restoration rather than consumption—demonstrating how thoughtful, empathetic design can revive degraded spaces into inclusive sanctuaries for both people and nature.
