Not everyday you encounter an architecture that envelops you in a cocoon-like, organic and deeply elemental embrace. Located in the beautiful landscapes of the undulating hills of Pune, at Swastik Wellness, it's not just about aesthetics, there's a lot more. The smooth flowing forms of ferrocement mimic the contours of a cave, the air is crisp with a sense of stillness, and light filters through thoughtfully carved apertures, creating an interplay of shadow and warmth that feels almost womb-like.
At the heart of this architectural philosophy is Manish Banker, principal architect at TAOStudiO, who has redefined what a retreat can be. At Swastik, the retreat doesn't simply sit in the landscape - it becomes part of it. The Guhas, subterranean yet bathed in natural light, provide an unparalleled sense of insulation from the outside world while maintaining a seamless connection to nature. And then there's a halotherapy chamber - the first of its kind in India, a space where architecture meets ancient healing, recreating the microclimate of a salt cave for deep respiratory therapy.
In a conversation with Zee Zest, Banker takes us through the meticulous thought process behind the Guhas, the challenges of building within nature rather over it, the technical innovations that allowed for seamless organic forms, and the philosophy that drives his approach to wellness architecture.
Edited excerpts:
1. What was the core inspiration behind the interior design of the Guhas (caves)? How does the interplay of light, materials, and space enhance the feeling of being ‘within the womb of Mother Earth’?
The idea of the Guhas, here are designed to go close to provide an experience which is organic and displays an intimate quality. This would facilitate the seeker to sync with oneself, specially after going through the various wellness active programs. The Guhas, hidden under the hilly terrain, are further insulated thermally, acoustically, and visually to generate a unique space, while being well taken care of, with natural light, ventilation and various other required engineering services. FerroCrete; as a technology has been used to achieve organic formation of structures to achieve the flexibility with light weight structure while blending with natural contours and existing natural trees and vegetation.
The Guhas are well served with modern-day, high-end comforts with equipment’s like air- conditioning (HVAC) and sanitation accessories to meet the standards of luxury living. The homogenous interior finishes that runs from the ceiling, to the walls and floors are meant to encourage seekers to walk bare foot in order to meet the required earthing of bio-electricity, charging our bodies.
2. What kind of sensory experience did you aim to create for the residents or guests?
The sensoria experience is the key criteria behind the Guhas as a space for people to enhance their five senses as a combined experience, together. The Guhas are meant to provide a paradigm shift from typical urban scenarios which are driven by industrial and digital worlds. As architects at TAOStudiO, the architectural design of Swastik has a great contribution to meet its international standards of infrastructure while touching the essence of centuries old wisdom rooted in Indian science of health and well- being.
3. What were some of the most innovative design solutions/materials you implemented in this project?
Every space is thoughtfully planned to preserve the natural environment. The structures seamlessly integrate with the hilly terrain, fostering a deep connection with nature. Preserving existing trees was a priority, leading to the creation of courtyards around them, ensuring minimal disruption and maintaining ecological harmony. For sustainable architecture, choosing the right elements is key. At Dhyan Vihar, tensile roofing creates large, column-free spaces, allowing natural light to reduce artificial lighting needs and maintain a serene and calm atmosphere. Ferrocement technology shapes the hills and connects plants, which insulates and cools the building without using as many HVAC systems. Additionally, the surrounding greenery helps local wildlife and enhances the quality of the air.
4. Were there any unexpected challenges in translating the architectural vision into interior spaces? Especially working with curved, fluid surfaces in interior spaces?
Yes, some unexpected problems were caused by the site's natural slopes, the large number of structural needs, and the unique requirements of a wellness retreat. Because the ground at the site was not level, creative design solutions were needed to make the organic structures blend in with the landscape while keeping them stable and easy to reach. A big challenge was making sure that the ribbed cell structures of the ferrocrete could adapt to the hills without having to be dug up too much. The process was made even more difficult by the need to balance the structural stability of curved shapes with the need for natural light, air flow, and low energy use.
Also, the retreat had a lot of different practical needs. It had to have a lot of wellness spaces, like big meditation halls, hydrotherapy zones, and rooms for holistic treatments. This meant that the space had to be carefully planned. It took a lot of material testing to make spaces that felt open, calm, and connected while still providing private and soundproofing for wellness activities.
Additionally, it was hard to find long-lasting, high-quality materials that fit with the project's eco-friendly goals. Using rescued teakwood and recycled fabrics meant that the interiors had to be carefully put together to look good together. Along with these problems, the result successfully combines architecture and nature, creating a retreat that is both safe and emotionally healing.
5. How do the interiors balance the concept of being cocooned within nature while offering modern luxury?
The ribbed ferrocrete shell makes the insides smooth and moving, which makes the space feel more relaxing. The appearance and air quality are both improved by high-quality finishes, and big windows allow natural light and beautiful views, strengthening the connection with nature. Ambient lighting and climate control are examples of contemporary luxuries that are seamlessly fitted.
Bathrooms with a theme based on nature; have stone flooring and rain showers, and furniture provides additional comfort. Private front yards add to solitude, and thoughtful design carefully frames nature through well-placed openings while ensuring privacy. This mix of natural materials and contemporary amenities lets guests enjoy both the soothing presence of nature and the luxurious comforts of modern healthy living.
6. How did ferrocement technology shape the interior design possibilities?
No other material, in my view as an architect, could truly capture our vision for the Guha. Ferrocement has provided for endless design possibilities for wellness retreats, allowing rooms and buildings to merge seamlessly with the hilly landscape, embodying the essence of Mother Earth. Material quality shapes design, and maximizing their potential is key. Ferrocement’s flexibility, thin walls, and structured form allow it to be sculpted into organic, cave-like spaces that evoke warmth, safety, and a deep connection to the earth. Its adaptability also enables the integration of essential services, reducing the dependency on artificial temperature control while ensuring natural comfort. Built-in seating and sculpted surfaces enhance simplicity, minimizing visual clutter to create a tranquil atmosphere. Ferrocement has been instrumental in crafting immersive spaces that foster healing by reconnecting individuals with nature and themselves.
7. Can you elaborate on how you incorporated wood wool into the design, and what impact it has on the overall ambience and functionality of the space?
Acoustics play a vital role in Dhyan Vihar, designed for lectures, Satsangs, and meditation. High-quality audio-visual equipment ensures clear sound with minimal echo, enhancing speech and music while reducing listener fatigue. Wood wool is used for its sound insulation, thermal control, and natural aesthetics, fostering a serene atmosphere ideal for meditation. Layered designs and pyramid-shaped panels optimize sound absorption, while its earthy texture complements the overall language set for Swastik aesthetic. Thoughtfully integrating sound and light, the design enriches the overall experience at Dhyan Vihar.
8. What elements of design - lighting, materials, spatial layout - have the greatest impact on relaxation and healing? According to you, what are the most critical architectural and interior design elements that contribute to a true sense of well-being?
Every component of a space has an impact on the occupants' well-being. By making careful choices about materials, lighting, and layout, a balanced design creates a space that encourages relaxation and personal growth, which is good for both physical and mental health. Designs that are inspired by nature combining spaces and technology promotes the overall wellness of individuals.
Here, spaces are planned to make the most of natural light, passive cooling, and cross ventilation, which creates an ideal environment for living. Long terraces and well-maintained yards make it easier to enjoy outside activities, and the focus on natural light means that standard HVAC systems aren't needed as much, making the home a peaceful escape from city life. There are no sharp edges or curves in the design, and it uses natural elements like warm colors and organic furniture to create a calm space that is good for your health as a whole.
9. If you could design your dream wellness retreat without any limitations, what would it look like?
Although limitations can be viewed negatively, they can really inspire innovation and creativity by pushing us to think creatively and unconventionally. Constraints, whether they be monetary, geographic, or environmental, assist us in prioritizing and honing our ideas, whereas limitless resources could cause indecision. These constraints encouraged creativity at Swastik, allowing us to concentrate on what was actually required, leading to thoughtful and purpose-driven design.
If I could build without restrictions, I would include contemporary technologies for comfort and safety while creating areas that blend in with the environment. Focusing on the knowledge of ancient architecture, the design would use organized space as a means of promoting health and healing. We strive for such values, yet modern expectations frequently limit us. However, technology should promote holistic growth while preserving our cultural and ecological foundations. My ideal scenario is one in which the landscape dictates the constructed environment while keeping nature at its core. Each component would permit artistic expression while honoring the ecosystem. A place where innovation, tradition, and nature coexist peacefully.
10. How difficult was it to get the halotherapy space right, given that it’s the first in India?
To replicate a salt cave's microclimate while balancing practicality and aesthetics, the halotherapy area was carefully constructed. The area required to maintain enough ventilation, regulate humidity, and disperse dry salt uniformly for optimal therapeutic effects. To achieve this, it was necessary to choose materials that would not degrade in the presence of salt, add natural salt colours, and design cave-like, textured spaces using suitable furnishings to enhance the experience. In addition to ensuring ideal air quality through integrated climate control systems, lighting was crucial for creating a relaxing environment and supporting recovery. Combining these technical components with the organic feel of a salt cave was difficult but necessary for a relaxing healing atmosphere.
11. Lastly, what sets apart Swastik?
Meaningful design doesn’t disrupt nature—it blends with it. To protect and enhance the environment, architecture should be inspired by the landscape. Thoughtful choices in materials, orientation, and layout help buildings merge naturally with their surroundings. This philosophy guided our approach at Swastik. We saw challenges as opportunities to create spaces that complement nature. By prioritizing sustainability, natural light, ventilation, and locally sourced materials, we ensured our design harmonizes with its environment. Nature itself is a healing force, and our project nurtures this by providing a space for natural healing. Swastik stands out for its integration of design and nature, encouraging inner reflection and a deep connection to the surroundings. Set in a scenic landscape, it has evolved organically, offering guests the comfort of open-air living within nature-inspired architecture.
