The Communal Lightbox
Reimagining public market architecture through sustainable urban design to empower street vendors and revive Mangaluru’s civic heart.
In rapidly transforming Indian cities, the pressure of globalization and Westernized lifestyle patterns has significantly altered the character of public spaces. Traditional markets — once vibrant social condensers — now struggle with spatial deterioration, vendor displacement, and ecological stress. The Communal Lightbox, a thesis project by Neethi Acharya, responds to this urgent condition through a powerful framework of sustainable urban design and inclusive public market architecture.
Located in the historic Hampankatta commercial center of Mangaluru, Karnataka, the project redefines the relationship between formal and informal economies, positioning architecture as a bridge between civic dignity, environmental responsibility, and social empowerment.
The Crisis of the Informal Market in Indian Cities
Indian cities generate employment for thousands through informal economies, especially street vendors. In Mangaluru’s Central Market (formerly known as Webster Market), the informal sector operates alongside formal shops, yet without spatial recognition or infrastructural support. Vendors face harassment, poor facilities, waste mismanagement, and marginalization within the urban fabric.
The Communal Lightbox questions conventional public project approaches:
- Are we designing for rigid systems instead of transitional realities?
- Can architecture empower instead of restrict?
- How can urban markets evolve without erasing their informal vitality?
Through sustainable urban design principles, the proposal reframes the informal sector not as a problem to be controlled, but as an essential urban asset to be integrated.
Site Context: Hampankatta, Mangaluru
Strategically located along Market Road, the site functions as a connective spine between the old and new parts of the city. The surrounding area is dense, layered, and continuously active — characterized by narrow lanes, hawkers, meat markets, vegetable stalls, and heavy pedestrian movement.
Activity mapping studies (morning, afternoon, and evening) revealed:
- Strong pedestrian circulation patterns
- Informal vending spillovers into traffic zones
- Waste accumulation and inefficient disposal systems
- Lack of shaded public interaction spaces
Rather than imposing a new object, the project stitches into the existing urban fabric — enhancing movement, spatial clarity, and ecological responsiveness.
Concept: The Market as a Civic Bridge
The Communal Lightbox acts as a porous urban connector. Instead of separating vendors from the formal market, it creates layered spatial zones:
- Vending Zones integrated within the structure
- Fruit, Fish, Meat, and Vegetable Markets organized with clarity
- Public Meeting Spaces and Lounges overlooking activity
- Recycling Workshop and Eco-Composter Units embedded within the program
The architecture becomes both infrastructure and social platform — encouraging accidental encounters, community events, and civic pride.
Sustainable Urban Design Strategies
1. Climate-Responsive Roof and Louvers
The building form incorporates south-facing skylights and a louvered exterior system designed according to sun path analysis (solstice and equinox studies). This reduces heat gain while maximizing diffused daylight, lowering energy consumption.
Natural ventilation strategies significantly reduce reliance on mechanical systems, aligning the project with sustainable public market architecture practices.
2. Material Palette Rooted in Local Context
The structure uses:
- Timber framing systems
- Refurbished louvered facades
- Mangalore tile roofing
- Granite stone flooring
- Composite structural columns
Wood usage reduces lifecycle carbon emissions compared to steel and concrete. By incorporating locally available materials and debris reuse strategies, the building reinforces environmental stewardship.
3. Waste Segregation and Circular Systems
Markets produce significant organic waste. Instead of treating waste as an afterthought, the Communal Lightbox integrates:
- Segregation points
- Eco-composters
- Recycling workshops
- Timed waste collection zones
Food waste is processed within 24 hours and converted into manure, generating revenue and promoting circular economy principles within the market ecosystem.
4. Aquifer Recharge and Water Management
Despite heavy rainfall, Mangaluru experiences groundwater depletion. The proposal introduces aquifer recharge systems and underground storage chambers to replenish groundwater levels — ensuring resilience against urban water scarcity.
Architecture as Social Infrastructure
Beyond function, the project recognizes the market as a social hub. The central spine transforms throughout the day:
- Morning: Fresh produce trade
- Afternoon: Mixed activity and workshops
- Evening: Community gatherings and events
Temporary urban furniture allows flexible use. Seating terraces, shaded boulevards, and upper-level viewing decks foster interaction between vendors, customers, and residents.
The building’s sectional strategy visually connects levels, ensuring transparency and inclusion rather than segregation.
Empowering Street Vendors Through Design
Protection of street vendors is central to the thesis. Instead of isolating them in peripheral zones, the project provides:
- Clearly demarcated vending infrastructure
- Access to storage and sanitation
- Platforms designed according to specific selling habits (fish mongers, vegetable vendors, fruit sellers)
- Modular stall systems inspired by hexagonal pod studies
This approach formalizes dignity without erasing the spontaneity of informal trade.
Short-Term Influence and Long-Term Impact
In the short term, the Communal Lightbox revitalizes public space by:
- Organizing circulation
- Reducing waste
- Providing structured vending areas
- Enhancing pedestrian experience
In the long term, it demonstrates how sustainable urban design can reshape public market architecture across Indian cities — integrating environmental systems, social equity, and contextual sensitivity.
By embodying the principles of the three Rs — Reduce, Reuse, Recycle — the project becomes an educational device, encouraging conscious consumption and community participation.
A New Urban Imagination
The Communal Lightbox is not merely a building; it is a proposition. It challenges the dichotomy between formal and informal, between sustainability and economy, between structure and spontaneity.
Through thoughtful public market architecture and sustainable urban design, Neethi Acharya’s thesis envisions markets not as chaotic leftovers of tradition, but as evolving civic institutions — generous, inclusive, and environmentally responsible.
In doing so, it restores pride to the street vendor and reclaims the market as the beating heart of the city.
