About Metamorphosis Yoga Shala Building

This project is about a Yoga Shala proposal submitted in an International Architecture Competition Call. The site is part of a mountain Yoga Retreat Complex located in a breathtaking forest region of central Portugal. The new Yoga Shala building is inspired from the Yoga philosophy, being a spiritual practice rather than a physical exercise. The new development apart from the Shala with an atrium space, consists of the Teahouse cave volume. Both buildings are framed by the biomorphic xeriscaping garden islands, the curvilinear walking concrete stone paths and the cultivation activities levels.

Interviews

Grand Interview

Your innovative approach to the Metamorphosis Yoga Shala Building draws inspiration from the butterfly cocoon - could you elaborate on how this biological transformation process influenced your architectural decisions and the building's final form?

Symbolism was a fundamental element throughout the design development of the Metamorphosis Yoga Shala. The building’s form establishes a dialogue with the philosophy of yoga, embodying notions of rebirth, inner transformation, and spiritual ascension. The cocoon — as a biological vessel that shelters the metamorphosis from a grounded, humble state into something ethereal and elevated — emerged as an ideal conceptual framework for the project.The architectural form evolved through an iterative process initiated by the study of the cocoon’s structural logic. A series of simplified morphological models were generated through the rotational transformation of basic curves, seeking to capture the cocoon’s organic integrity. During this exploratory phase, these curves gradually began to evoke the outline of the human embryo — a symbolic reference to potential, renewal, and the genesis of change.The final expression of the building represents the moment when the cocoon has opened and the butterfly has been released — a spatial metaphor for liberation, awakening, and transcendence, aligning archit

The integration of the Metamorphosis Yoga Shala Building into the Portuguese forest landscape presented unique challenges - how did you balance creating a landmark structure while maintaining harmony with the natural surroundings?

The integration of the Metamorphosis Yoga Shala into the Portuguese forest was approached as a dialogue between harmony and contrast. While the organic form allows the structure to merge naturally with its surroundings, the titanium cladding introduces a subtle tension — a reflective skin that captures the shifting light and atmosphere of the forest, emphasizing the transient and transformative essence of the project.In contrast, the interior unfolds in warmth and intimacy through the use of timber surfaces, evoking a sense of grounding and connection to the natural world. This material duality — between the cool, metallic exterior and the tactile, wooden interior — mirrors the balance between the physical and the spiritual that yoga embodies.The surrounding landscape was designed as a transitional space, featuring a xeriscape garden that gently mediates between the forest and the architectural form. At the heart of the composition lies an open courtyard, conceived as a place of pause and reflection — a moment of stillness where practitioners can reconnect with nature and self after their practice.Through this interplay of contrasts, the Yoga Shala becomes both a landmark and a retreat: a structure that asserts its presence through quiet resonance rather than dominance, and one that, much like the act of metamorphosis itself, exists in a continuous state of balance between stillness and change.

The Metamorphosis Yoga Shala Building incorporates both spiritual and practical elements - could you share how the philosophy of yoga influenced your design choices, from the atrium space to the teahouse cave volume?

The philosophy of yoga informed the design not only through spatial composition but through the very essence of transformation embodied by the cocoon metaphor. Just as the cocoon shelters the process of metamorphosis, the building was conceived as a protective envelope — a place where body and mind can retreat, evolve, and eventually emerge renewed.Within this conceptual framework, the atrium functions as the heart of the organism — a breathing core that channels light and air, symbolizing the act of inhalation and the expansion of consciousness. Its openness contrasts with the stillness of the Teahouse, which, embedded within the mountain, represents the moment of withdrawal and introspection. This descent into the earth mirrors the grounding phase of practice, where awareness turns inward before ascending once more.The dialogue between these two spaces reflects the rhythm of yoga itself: expansion and contraction, lightness and grounding, transformation and rest. Through this interplay, the building transcends the distinction between the spiritual and the practical — it becomes an architectural cocoon, nurturing both the physical experience of space and the inner evolution it invites.

Unique Properties
The Building program, consists of the new Yoga Shala with an Atrium, the Xeriscape Garden islands, the Stone Teahouse carved in the sloped ground along with the Cultivation Levels. The Teahouse serves as a neutral background, while the organic shaped garden islands define the layout of the circulation paths and seating areas. The Atrium with the Olive Tree, add spatial quality, while the cultivation plantings provide cultivating activities that enhance the experience of the visitors.
Dimensions & Packaging
The structure of the building consists of primary and secondary structural wood contour beams grid. A horizontal perimetric bench-like shelf, reinforces the structure stiffness while serving as a seating bench. The skin of the building is comprised by layers of plywood sheets, thermal insulation and structured titanium panels.
The Yoga Shala curved building skin incorporates photovoltaic panels. It has the adequate thermal insulation and a Pasiv Haus construction envelope in order to maximize energy efficiency. The openings allow for adequate natural lighting and aeration. The rainwater and greywater are purified and stored in a water tank.

Production Technology
The form of the new Yoga Shala was produced by the geometric transformations of the model of the Butterfly Cocoon. The complex geometry of the cocoon gently surrounds and hosts the caterpillar throughout its metamorphosis to a brilliant butterfly. The geometric study of the cocoon and its necessary form simplification, was ultimately derived by an iterative process of revolved geometries of a typical cocoon cross section till the birth of the Butterfly.
Design Challenge
The most demanding feature of the design, was the incorporation of a the bubble shaped, metallic buiding into the forest landscape. The demand for a dynamic and recognizable building form, that would serve as a landmark to the Yoga Retreat site, led to the creation of the organic and biomorphic Yoga Shala.
Research
The Geometry of the Yoga Shala is based on the Butterfly Cocoon Transformation. The form of the Yoga Shala building and its materiality is also connected to the construction of the Vernacular Indian Huts. It has been derived by the revolution in space of an Organic Form Curve along an axis that divides the form in two separate and clearly defined volumes, interconnected with each other to create the Cocoon shaped Shala. Each part of the curve is revolved an angle in order to create a closed shape. Two overhangs, one in each block, are created by an additional revolution around the same axis of rotation.
Inspiration
The geometry of the new Yoga Shala has been inspired by the Butterfly Cocoon. The Metamorphosis of the clumsy and worldly caterpillar which transforms through an extraordinary biological process to a graceful Butterfly, is the core idea behind the building form and construction. Yoga practice is a personal journey towards enlightenment and the True Self. It means Connection, and this journey will only be authentic through the conceptualization and realization that everything is interconnected.
Project Duration
The project started in October 2020 and ended in December 2020. It is located in a breathtaking region of central Portugal, in an old
abandoned valley farm which has been transformed to a Yoga Retreat Center. This proposal represents the Bureau's participation in an International Architecture Competition Call, which requested the design of an additional Yoga Shala space to the existing complex.
Operation Flow
The floor plan is organized into the organic shaped volume of the building. There are two independent entrances, one leading to the Shala and the other one to the Xeriscape Atrium. The wide glazing openings allow for natural lighting thus enhancing the warmth and hospitality of the space. The storage of the yoga equipment is incorporated in the wooden structure of the building, under the perimetric seating bench and on shelves constructed between the primary structural beam contours. In the corner of the Yoga Shala, Aerial Yoga Swings may be hanged from the structural Beams supporting this activity with safety.
