Natural Ventilation and Rainwater Harvesting in Modular Microhomes With Corrugated Plastic Roofing

Project in-detail

Utilizing corrugated plastic roofing and advanced rainwater harvesting systems, the design creates sustainable microhomes that prioritize natural ventilation and community resilience in the heart of Mumbai's densely populated Dharavi slum.
5 key facts about this project
01
The design incorporates a modular framework that allows for future adaptability based on changing community needs.
02
Rainwater harvesting systems are integrated to promote self-sufficiency and reduce reliance on external water sources.
03
Shared community spaces are included to foster social interaction among residents in a densely populated environment.
04
Natural ventilation strategies are utilized to enhance indoor comfort while minimizing energy consumption.
05
Corrugated plastic roofing provides lightweight protection and diffuses natural light into the living spaces.
The architectural design project focused on the Dharavi Slum in Mumbai embodies a thoughtful approach to urban living, presenting a comprehensive response to the challenges faced by residents in one of the world's most densely populated areas. This project represents a blend of functionality, sustainability, and community engagement, aiming to enhance the quality of life for its inhabitants while maintaining sensitivity to their socio-cultural context.

At its core, the project seeks to provide microhousing that is both affordable and adaptable. The housing units are designed with modular elements, allowing for flexibility and variation based on the specific needs of families living in this vibrant yet constrained environment. Each microhome features a layout that intelligently separates living and working areas, which is essential given the dual-purpose nature of life in a slum. Residents often conduct small-scale businesses from their homes, necessitating a design that accommodates both personal privacy and communal interaction.

The choice of materials used in the construction underscores the project’s commitment to affordability and sustainability. Durable bricks form the principal structure, providing necessary stability while concrete offers a strong foundation that can withstand the rigors of daily life in an urban environment. The use of timber for columns adds a lightweight yet robust touch, ensuring that the overall framework is solid yet flexible enough to adapt when required. One of the project’s standout features is the roof, constructed with corrugated plastic sheets. This design not only protects against the elements but also allows for diffused natural light to brighten the indoor spaces.

A significant aspect of the design is the integration of shared amenities, such as laundry and storage facilities. These common areas encourage community interaction and cooperation among residents, providing opportunities for social bonding in a space that often faces isolation due to its dense living conditions. This social dimension is further amplified by the provision of a flexible roof space that can be utilized for community gatherings or workshops, promoting a sense of ownership and togetherness within the micro-community.

Sustainability is a guiding principle throughout the architectural design. The project incorporates solar panels on the rooftops, tapping into renewable energy sources to meet the electricity needs of the residents. Additionally, rainwater harvesting systems are installed, allowing for the capture and storage of rainwater, which reduces reliance on external water supplies—an important consideration in a city where access to clean water can be a challenge. The design also emphasizes natural ventilation, using airflow strategies to keep indoor spaces comfortable without the need for energy-intensive cooling systems.

In terms of its unique design approaches, this project stands out by focusing on the specific realities of slum living. Rather than imposing external ideals of architecture, the design reflects an understanding of the complexities of daily life in Dharavi. It addresses multifaceted issues such as overcrowding, limited resources, and social dynamics, creating a housing solution that is not only functional but also empowering.

The exploded isometric drawings provided in the project documents illustrate the intricate relationship between various structural components, revealing a coherent assembly logic that ensures ease of construction and potential for future modifications. This thoughtful approach is indicative of a broader trend in contemporary architecture that seeks to blend practicality with an understanding of community needs.

For those interested in a deeper understanding of this architectural endeavor, reviewing the architectural plans, sections, and designs will provide further insights into its innovative solutions and design ideas. This project serves as a testament to how well-considered architecture can meaningfully influence and improve lives in challenging urban environments.
