Carbon Garden Pavilion: Sustainable Architecture at Kew Gardens

The Carbon Garden Pavilion at London’s Kew Gardens represents a new intersection of architecture and ecology. Designed by Mizzi Studio, the pavilion forms part of the newly introduced Carbon Garden, a landscape that demonstrates the essential role of carbon in sustaining life on Earth. Its mushroom-like canopy, crafted with natural and bio-based materials, invites visitors into an environment where design merges with scientific storytelling.

The pavilion is more than a shelter. It is a living metaphor, designed to function as an educational and spatial extension of the Carbon Garden. By combining stone foundations, timber structure, and a translucent flax-fibre roof, the design balances permanence with lightness. Positioned carefully to align with the sun path, it reflects how architectural thinking can embody ecological processes. The project contributes not only to the visitor’s experience but also to the ongoing dialogue on sustainable architecture. With its thoughtful integration of form, material, and purpose, the Carbon Garden Pavilion demonstrates how buildings can act as mediators between natural systems and human activity.

Design and Materiality

The pavilion is characterized by a form that blends natural inspiration with structural precision. Its wooden frame rises from foundations of larvikite stone, supporting a canopy of flax fibres and resin. The result is a space that feels both organic and crafted, creating a translucent surface that filters warm light beneath.

Element	Material	Purpose
Foundation	Larvikite stone	Durability and avoidance of concrete
Frame	Glued-laminated larch timber	Structural strength with sustainable sourcing
Canopy	Flax fibres and resin	Translucency, light diffusion, natural expression
Feature element	Recycled polycarbonate funnel	Rainwater harvesting for the garden

Spatial Experience

Positioned at the heart of the Carbon Garden, the pavilion is angled toward the southern sun path. Its canopy creates a sense of intimacy while maintaining capacity for groups, making it suitable for school visits and community events. The design draws parallels with plants that use form and color to attract pollinators, reinforcing its symbolic role as a mediator between people and ecological systems.

Architectural Analysis

The design logic of the Carbon Garden Pavilion is rooted in the symbiotic relationship between plants and fungi. By referencing a mushroom-like form, Mizzi Studio offers an architectural translation of ecological interdependence. Material use follows a natural hierarchy: stone as a stable base, timber as a vertical structure, and flax fibre as a lightweight canopy. This layered approach communicates both structural rationality and symbolic depth.

The context of Kew Gardens amplifies the project’s impact. Surrounded by a landscape dedicated to research and conservation, the pavilion becomes a didactic tool. Its translucent canopy and organic geometry align with Kew’s mission of demonstrating how science and design can address climate challenges. Critically, the pavilion raises the question of permanence: can such lightweight bio-based materials endure in the long term, or are they intended to highlight temporality as part of their narrative? The answer may influence future architectural typologies.

Project Importance

For architects and designers, the Carbon Garden Pavilion illustrates several lessons. First, it demonstrates how materials like flax fibres can be scaled beyond product design into architectural applications. Second, it shows how symbolic form can coexist with functional demands, enabling spaces that are both poetic and practical. Third, it emphasizes the importance of situating projects within cultural and ecological contexts, allowing architecture to speak with the landscape rather than dominate it.

The project contributes to architectural thinking by questioning how sustainable building materials can create new typologies. Its hybrid identity between shelter, sculpture, and ecological system reflects a design direction that is urgently relevant today. At a time when the construction industry seeks lower-carbon solutions, the Carbon Garden Pavilion serves as a prototype for integrating innovation with narrative-driven architecture.

✦ ArchUp Editorial Insight

The Carbon Garden Pavilion stands out through its translucent canopy, stone base, and timber frame, forming a composition that feels both crafted and natural. The interplay of filtered light, warm tones, and organic geometry defines the visitor’s experience. However, the reliance on experimental bio-based composites raises questions: how resilient are these materials when exposed to long-term weathering, and what maintenance strategies will be necessary? This constructive concern does not undermine the value of the project but instead emphasizes the need for continuous testing. Ultimately, the pavilion provides a compelling model of how architecture can merge research, form, and ecological engagement, offering valuable lessons for future design practice.

Conclusion

The Carbon Garden Pavilion at Kew Gardens is a synthesis of architecture, science, and ecology. It is a space where structural logic, material exploration, and symbolic meaning converge. Through its stone foundation, timber frame, and flax-fibre canopy, it embodies a layered narrative of durability, sustainability, and lightness. The integration of a rainwater harvesting system further reinforces its role as an active contributor to environmental cycles.

For visitors, it is both a shelter and a statement, offering an intimate encounter with the possibilities of sustainable architecture. For architects, it presents a case study in how design can respond critically to ecological imperatives while remaining experiential and meaningful. In a global context of climate urgency, the Carbon Garden Pavilion demonstrates how architectural practice can be reoriented toward resilience, innovation, and ecological literacy. As part of Kew’s broader mission, it contributes to an evolving dialogue on how the built environment can sustain life rather than merely occupy space.
