Sustainability has transitioned from being a trendy buzzword to becoming the bedrock of contemporary architecture and interior design. As environmental concerns grow more pressing, professionals in the industry are championing innovative, eco-conscious methods to create spaces that are not only visually stunning but also environmentally responsible.
In this article, we spotlight three design luminaries who are redefining sustainable design with their visionary approaches: Christina Sengupta of CS Interiors, Ar. Rahul Dodthi of Avighna India, and Ar. Ranjita Gavandi of PRAG OPUS LLP. From integrating ancient wisdom with modern technology to utilising reclaimed materials and AI-driven systems, these trailblazers are leading the charge in shaping a greener, more thoughtful future for architecture and décor. Christina Sengupta, Head of Design & Execution at CS Interiors, believes sustainability is an intrinsic part of living in a city like Mumbai, where resources are finite, and spaces are compact. “Sustainability, especially in Mumbai, is essential due to the city’s resource limitations and diverse demographics. We design with budget consciousness, ensuring that even with limited resources, our designs are long-lasting,” she shares.
Christina Sengupta: Simplicity Meets Sustainability
Sengupta’s work emphasises creativity within constraints. In one of her standout projects—a bungalow in Igatpuri—she redefined eco-friendly luxury by incorporating recycled materials, bamboo, cane, and solar-powered lighting. Glass bottles were upcycled into planters, showcasing how waste can turn into art. “Balancing aesthetics and sustainability is about material choices. For instance, bamboo and cane are not just cost-effective but also durable and visually appealing,” she explains.
Looking ahead, Sengupta foresees a growing demand for interiors that blend sustainability with style. “New materials like charcoal sheets and PVC for ceilings are gaining traction. Clients are asking for spaces that reflect eco-consciousness while being functional and inviting.”
Ar. Rahul Dodthi: From Vision to Green Reality
With extensive experience in luxury residential and commercial projects, Ar. Rahul Dodthi brings a practical yet innovative lens to sustainable design. “To me, sustainability means creating spaces that minimise harm to the environment while promoting occupant well-being. It’s about considering the entire lifecycle of a building—from material selection to waste management,” says the seasoned architectural manager at Avighna India.
One of his notable projects involved modernising a 20-year-old apartment in a densely populated area. By reusing materials like wood flooring and cabinets, integrating energy-efficient LED lighting, and using low-VOC paints, Dodthi transformed the space into a model of eco-friendly design. “Sustainability and aesthetics are not mutually exclusive,” he insists. “With the right materials and smart systems, a space can be both functional and visually stunning.”
Dodthi highlights technology as a pivotal enabler. “AI and smart systems are revolutionising how we approach energy management. Imagine homes that adjust lighting and temperature based on occupancy—these innovations are the future of sustainable design.”
Ar. Ranjita Gavandi: Sustainability Rooted in Tradition
For Ar. Ranjita Gavandi, sustainability is a timeless principle that aligns with ancient Indian architecture. “Sustainability has always been there. Even the technical aspects of Vaastu are rooted in eco-conscious design. It’s about creating harmony between structures and their environment,” she says passionately.
One of her landmark projects, a Jain Temple complex in Indore, exemplifies her philosophy. The vast complex, featuring domed halls, classrooms, and guesthouses, is naturally ventilated and lit, negating the need for air conditioning. Solar panels power the premises, and stormwater management ensures efficient resource use. “We use natural materials to create serene, comfortable spaces. The main dome is an example of how functionality and aesthetics can coexist sustainably,” she elaborates.
Ar. Ranjita emphasises the importance of design orientation. “The sun’s path, wind direction, and natural ventilation are crucial in reducing artificial energy dependence,” she notes. Looking forward, she believes the blend of ancient wisdom and modern technology will shape the future. “Smart homes and AI are tools to enhance what we’ve been doing for centuries.”
The Unstoppable Shift
When asked whether sustainability is a fleeting trend, all three experts are emphatic: it’s a permanent shift. Christina emphasises education, “Clients need to see that sustainable choices are not just ethical but also economically wise in the long run.”
Ar. Rahul frames it as an industry imperative. “Climate change is no longer a distant threat—it’s here. Sustainable design is the only way forward,” he says.
Ar. Ranjita takes a philosophical view. “This isn’t new—it’s a revival of practices that have existed for centuries. The modern world is simply catching up,” she reflects.
Guiding the Next Generation
Their advice for young designers is unanimous: start with knowledge. Christina encourages designers to embrace the challenges of educating clients. “Start small—show them how tiny changes can have a big impact,” she suggests.
Ar. Rahul calls for a shift in mindset. “Think beyond aesthetics. Always ask yourself: What’s the environmental cost of this design choice?” he advises.
Ranjita urges designers to look both forward and backward. “Learn from history and stay updated on technological advancements. Both are crucial for sustainability,” she says.
The Future of Sustainable Design
Sustainability is evolving, and with it, designs trends. Christina sees a growing trend for eco-luxury. “People want homes that are not only green but also reflect their style and status,” she says.
Ar. Rahul predicts a surge in biophilic designs and net-zero buildings. “The integration of nature and technology will define the future,” he states.
For Ar. Ranjita, the future lies in merging traditional techniques with smart innovations. “We are moving towards a world where sustainability is not a choice but a seamless part of life,” she concludes.
