The Black Taj – Lal Dera: Ek Pani Ki Katha

Shortlisted Entry – The Black Taj Competition  

Reclaiming the Flow: Water Architecture in Sustainable Design

In the heart of Agra, where the Yamuna River still reflects the silhouette of the black Taj , Lal Dera: Ek Pani Ki Katha reimagines how architecture can revive the ecological wisdom embedded in Mughal design. Created by Kruti and Sebastian, this shortlisted proposal for The Black Taj competition brings together architecture, environment, and heritage through a system of water treatment pavilions that merge functionality with symbolism.

The project’s title — translating to “A Tale of Water” — pays homage to the Mughal “Lal Dera,” or the red pavilion, historically known as the center stage of royal courts. This reinterpretation transforms the dera into a regenerative landscape — a place of gathering, learning, and ecological care.

Rediscovering the Lost Wisdom of Mughal Water Systems

At its core, the project reflects on the forgotten sophistication of Mughal hydraulic systems — intricate networks of channels, tanks, and stepwells that sustained the empire’s gardens and cities. Lal Dera bridges this legacy with today’s urgent need for sustainable water infrastructure.

The proposal envisions a temporary yet transformative set of pavilions — modular, transportable, and open to the public. Each pavilion functions as a stage in the water purification process: from sedimentation and filtration to aeration and storage. But beyond its technical role, each space becomes a social and educational commons, allowing people to engage directly with water processes, understand ecological cycles, and participate in their renewal.

This dual function — technological and cultural — defines the essence of water architecture in sustainable design. It is not only about conserving a resource but also about restoring a relationship — between people, landscape, and heritage.

A Living Garden of Learning

The plan unfolds within a reinterpreted Mughal Charbagh, where geometry and water orchestrate the spatial rhythm. The eight interconnected zones host different pavilions — each addressing a phase in the water’s journey:

1. Absorption Pavilion – introducing water through natural filtration.
2. Primary and Secondary Treatment Pavilions – where layers of clay, gravel, and vegetation clean and oxygenate the flow.
3. Storage Pavilion – preserving processed water for reuse in gardens.
4. Participation Pavilion – designed for workshops and public engagement.
5. Testing Pavilion – where data and awareness meet physical design.

The architecture embraces transparency, modularity, and repetition, echoing the logic of Mughal gardens while reinterpreting it through a contemporary, lightweight vocabulary. The pavilions use perforated steel, woven screens, and terracotta palettes, creating a dialogue between craft and computation — between permanence and ephemerality.

Cultural Sustainability through Ecological Architecture

Lal Dera situates sustainability not as a technical pursuit but as a cultural continuum. It recognizes that ecological consciousness was already embedded in historic design traditions — from canal-fed gardens to rainwater courtyards. By reactivating this lineage, the project demonstrates how cultural sustainability can drive environmental resilience.

The landscape is populated with wetland flora such as Typha Latifolia, Acorus Calamus, and Papyrus, each species contributing to the natural treatment process. These plantings are not ornamental — they are infrastructural. They restore biodiversity, filter pollutants, and create microhabitats for urban wildlife, turning the site into a living laboratory for ecology and architecture alike.

Architecture as Public Infrastructure

The proposal also redefines architectural typology. Instead of monumental permanence, it advocates for flexible public infrastructure — an evolving system that can migrate, adapt, and grow. The use of mobile units, transportable modules, and adaptable geometries allows the design to respond to shifting contexts — from urban riversides to rural settlements.

This adaptability aligns with the social goal of accessibility. The pavilions double as educational spaces, where communities can learn about water treatment, sustainable gardening, and resource management. In doing so, Lal Dera blurs the line between architecture and activism — between building and behavior.

Reflections: The Black Taj and the Memory of Water

As part of The Black Taj competition, which challenges designers to reimagine the unbuilt twin of the Taj Mahal, Lal Dera positions water not as a backdrop but as the protagonist of architectural memory. It reframes the Taj’s reflective pools — once symbols of purity and transcendence — into systems of ecological regeneration.

In this reinterpretation, water becomes a living archive — it records, sustains, and transforms. The project’s narrative thus flows beyond aesthetics into ethics: to rebuild our cities, we must first rebuild our relationship with the natural systems that make them possible.

Architecture that Teaches, Heals, and Flows

Lal Dera: Ek Pani Ki Katha is not only a proposal — it is a philosophy of flow. It redefines water as architecture’s oldest and most vital collaborator. By combining Mughal spatial order with ecological engineering, Kruti and Sebastian offer a model of sustainable architectural design rooted in both heritage and innovation.

Through this project, Agra’s legacy of gardens and waterworks finds a new voice — one that teaches, heals, and continues to flow.
