Sharanam - Phase 2

During my time at the Auroville Earth Institute, I had the opportunity to work as a Site Engineer on the Sharanam – Phase II project, a Center for Rural Development in Pondicherry, undertaken for the Sri Aurobindo Society.

The project consists of four dormitory buildings (single- and double-story) and a conference facility, carefully arranged along a central masterplan axis. A poured earth concrete road connects the Phase I main hall to the Phase II development. The dormitories are designed with street-facing verandas (Thinnai), reflecting traditional Tamil architecture, and are enhanced with beautifully crafted vaulted masonry. The rooftops open up into spacious terraces, interconnected through suspended walkways, creating a cohesive and interactive built environment.

As a Site Engineer, I was actively involved in the execution and construction processes, with a strong focus on earth-based building techniques and structural systems. My work included the construction of arches, vaults, and domes, ensuring precision in geometry, alignment, and structural integrity. I coordinated closely with on-site teams, maintaining quality control in materials and workmanship.

I was also involved in the preparation and application of lime mortar and other natural materials, ensuring proper mixing, usage, and finishing techniques. Special attention was given to maintaining construction accuracy while adapting to on-site conditions. Through this hands-on experience, I developed practical skills in managing construction challenges, optimizing material usage, and effectively implementing sustainable building methods.

I am deeply grateful to have been mentored by Mr. Satprem MaÏni and Mr. Ayyappan. Working alongside the entire Auroville Earth Institute team was an inspiring and enriching experience that significantly shaped my approach to sustainable construction.

Sky Garden

The Sky Garden project involved the construction of a traditional vaulted structure on a third-floor terrace, transforming an underutilized rooftop into a functional and experiential space.

The vault was constructed using time-tested techniques, emphasizing the use of locally available materials and sustainable methods. This approach not only reduced dependency on modern high-energy materials but also enhanced the thermal comfort and aesthetic value of the space.

The completed terrace now functions as a serene sky-level retreat, combining structural elegance with environmental responsiveness. The project demonstrates how traditional construction techniques can be adapted to modern urban contexts, even in structurally challenging locations.

Shell Wall

The Shell Wall project was developed along a coastal site, where environmental conditions such as high humidity, salt-laden air, and strong winds played a critical role in material and construction decisions.

To respond to this context, a traditional lime-based technique known as poured earth concrete was adopted. This method combines natural materials with lime to create a breathable, durable, and environmentally responsive wall system—particularly suitable for coastal environments where conventional cement-based construction often deteriorates over time.

One of the key challenges was ensuring durability against saline exposure while maintaining structural integrity and finish quality. The use of lime not only enhanced resistance to salt corrosion but also allowed the wall to age gracefully, developing character over time rather than degrading. The construction process involved careful layering and compaction, ensuring consistency and strength throughout the wall. The result is a structure that is both robust and contextually rooted, blending seamlessly with the coastal landscape.

IQ

The IQ Project is a commercial development that explores the integration of sustainable building techniques within a contemporary concrete structural framework. The project focuses on creating a balance between modern construction demands and environmentally responsible design practices.

A key feature of the project is the use of soil-lime plastered walls, which provide breathability, thermal comfort, and a natural finish. Complementing this, oxide-finished walls were incorporated to enhance durability while maintaining a minimal and earthy aesthetic.

One of the primary challenges was achieving seamless integration between traditional, natural materials and a conventional reinforced concrete structure. Careful detailing and execution were required to ensure compatibility, finish quality, and long-term performance.

The IQ project stands as a demonstration of how sustainable materials and techniques can be effectively adapted to commercial architecture, creating spaces that are both functional and environmentally conscious.

Vellaithamarai School

The Vellaithamarai project focused on restoring an existing school through selective demolition, repair, and new construction using sustainable building practices.

The approach prioritized retaining usable structures to reduce waste, while replacing damaged portions with environmentally responsible construction. The result is a cohesive, functional, and naturally comfortable learning space that blends old and new seamlessly.
