Introduction

Lighting Bathroom was initiated to address the urgent need for dignified sanitation and public lighting in underserved communities lacking basic infrastructure. In New Delhi’s Sector 126, Noida—an informal riverside settlement frequently affected by monsoon flooding—residents live without access to safe toilets or lighting. Our site survey identified 25 immigrant families and 35 children living in this area, where women and girls are particularly vulnerable due to unsafe open defecation zones and the absence of nighttime illumination.

Impact

Our project strengthens long - term community development by centering local agency and ecological knowledge. Lighting Bathroom is not a one - time intervention but a replicable framework co - created with the community. By transforming agricultural and organic waste into biogas for sanitation and lighting, the pavilion becomes a self - sustaining hub of health, safety, and empowerment.

Core team

The Lighting Bathroom project is led by a multidisciplinary team combining international design leadership with strong local expertise and community collaboration.

Sangji Han – Architectural Designer (U.S.): Founder of the initiative, leading design vision, research, and coordination across continents.

Monish Siripurapu – Local Collaborator (India): Principal Architect at ANT Studio, New Delhi, providing technical oversight, local knowledge, and implementation support.

Aniruddh Sharan – Project Coordinator (U.S./India): Supports strategy, documentation, and community engagement.

Design x Design – Local Partner and Competition Host: Selected the project as Winner of the Waste Not Competition (2024, New Delhi), providing a $1,000 grant and facilitating connections to local professionals.

Since October 2024, the team has conducted extensive on - site research in Sector 126, Noida—a flood - prone, informal riverside settlement in New Delhi. The local community has been deeply involved from the beginning. Our feasibility study included:

A restroom usage survey to understand behavioral patterns and needs

Demographic research, identifying women, children, and immigrant families as key beneficiaries

Soil and civil infrastructure analysis to guide construction

Material and funding surveys to assess availability and affordability

We’ve already developed trust with local residents through prior collaborations and successful hands - on construction with community participation.

Where are we now

The design has won three international awards. The project was selected as Winner of the Waste Not Competition by Design x Design (New Delhi), receiving a $1,000 grant and connecting us with local partner ANT Studio. An additional $2,000 has been contributed by the partner toward the India pilot. Since October 2024, we’ve conducted feasibility studies, technical and infrastructure surveys, material and funding assessments, and built strong relationships with the local community—laying the groundwork for full-scale implementation.

An indication of our team’s capacity:

50% funding already raised

75% expertise already found

50% materials / equipment already found

100% builders already found

Finance: € 2,000

Additional funding will secure renewable energy products for construction and source sustainable materials, complementing the recycled bamboo and brick already secured around the site. It will also support a project site visit to New Delhi in September, facilitating a design workshop with local residents, enhancing communication with local partners, and guiding on-site construction details to ensure the project’s success and alignment with community needs.
