My work is a dialogue between nature and design. These projects show how we use passive cooling, local materials, and thoughtful planning to create buildings that breathe and foster well-being.

Children look out from a *jharokha* window at the Butterflies Resilience Centre. We used upcycled doors and windows from an old haveli, giving them a new home and weaving a sense of history and continuity into the building's fabric. For me, architecture must create these moments of simple joy and connection.

The central courtyard of our LEED Platinum certified office in Noida. The space is designed around a water body that acts as a natural heat sink, passively cooling the building and creating a tranquil heart for the workplace. This is how we build spaces that breathe.

A view of the IIHMR University campus in Jaipur, nestled in greenery. We used local stone and designed the buildings around linked courtyards, creating a space that feels rooted in its environment and encourages interaction and learning.

Here, I explain my approach to materials. We excavated the earth from the basement of the Butterflies Centre and used it to make the very bricks for its walls. By using what is already there, like second-hand doors and windows, we create buildings that are truly sustainable and cost-effective.

The vibrant facade of the Butterflies Centre in Delhi. These hand-painted louvers are not just for decoration; they are a dynamic shading system that controls sunlight. This is an example of how we integrate art with function to create buildings that are both beautiful and intelligent.

A shaded pergola at the IIHMR Jaipur campus. I believe in creating gentle transitions between the indoors and outdoors. These spaces offer respite from the sun and invite people to walk, pause, and connect with nature.

This is the custom-made trickle fountain in our Noida office project. The sound and sight of water are calming, but it also serves a practical purpose. It is part of a larger evaporative cooling system that helps manage the building's microclimate with minimal energy.

A portrait of myself. After five decades in architecture, my commitment remains the same: to design and build spaces that are responsible, gentle on the earth, and bring a sense of well-being to the people who inhabit them.

About Featured

For many of these projects, we do not simply rely on materials ordered from a catalogue. Instead, we excavate the earth directly from the building site, stabilize it, and turn it into bricks for the walls. This creates a structure that literally rises from the ground it stands on, significantly reducing our carbon footprint while keeping the interiors naturally cool and comfortable.

I have spent my career designing spaces that feel alive, moving away from energy-heavy boxes toward structures that connect with their environment. Whether it is a university campus or a community centre, my approach remains the same—observe the sun, the wind, and the history of the site, then build something that lasts.
