The Golden Spiral Pavilion is a large-scale, modular, and reusable bioclimatic textile structure implemented at the Boom Festival in Idanha-a-Nova, Portugal.
Designed to address the challenge of providing thermal comfort in extreme heat (40°C+) without mechanical cooling, it integrates sacred geometry (Fibonacci sequence) with passive design principles. My main inspiration came up when I was reading about biomimicry.
The structure features a unique ascending spiral of fabric strips that promotes natural convection and cross-shading, drawing hot air upwards and creating a significantly cooler environment at ground level.
Achieved Results: Since its first implementation in 2018, the pavilion has been successfully re-mounted four times (2018, 2022, 2023, 2025)
It has provided high-efficiency thermal comfort for over 2,000 participants, hosting more than 140 hours of cultural content
Users and festival managers consistently identify it as the "most comfortable tent at the festival"
Long-term Impacts: The project exemplifies circular infrastructure. While the textile "skin" is designed for a minimum of two editions (partially replaced in 2023), the core structural components—galvanized steel cables and a robust recycled wooden post—have a demonstrated lifespan of over 10 years
Furthermore, the project achieved a successful knowledge transfer, empowering the local festival production team to re-mount the complex structure independently for the last three editions
It stands as a proven, replicable model for reducing the environmental footprint of global temporary events

The project was born from the Boom Festival 2018 theme, "Sacred Geometry," which sought innovative solutions aligning sustainability with art.
. As a specialist in geodesic domes and innovative structures, I proposed a design that went beyond aesthetics: a pavilion that functioned as a living bioclimatic organ
. The goal was to prove that temporary festival infrastructure could be both beautiful and regenerative, moving away from single-use models toward permanent circular assets.
Implementation: The implementation combined advanced engineering with resource optimization. We used a recycled wooden post from a previous project and recycled polyamide fabric to minimize initial impact
. The technical heart of the pavilion is a radial system of galvanized steel cables that allows for a large-span, open-air structure
. In 2018, I led the first construction, focusing on training the festival’s rigger
. This "design-for-disassembly" approach was critical; by providing detailed anchoring and cable diagrams, I ensured the project could live on without my constant presence
. The story of this pavilion is one of resilience: it survived years of storage and has been reborn in multiple editions, with its original fabric even being repurposed into festival furniture (puffs and small shades) at the end of its first lifecycle, truly closing the loop

The Golden Spiral Pavilion addresses the critical environmental challenge of providing thermal comfort for large gatherings in extreme heat (40°C+) without relying on energy-intensive mechanical cooling
. By integrating bioclimatic principles with a unique ascending spiral configuration, the design promotes natural convection and cross-shading, drawing hot air upwards and creating a significantly cooler environment at ground level
. Economically and environmentally, the project challenges the "single-use" paradigm of festival infrastructure
. It follows a "Design for Disassembly" approach, utilizing a circular "kit of parts": a recycled central wooden post, galvanized steel cables, and modular metal components designed for a lifespan exceeding 10 years
. The use of recycled polyamide fabric further minimizes initial impact, and its planned replacement in 2023 demonstrates a circular lifecycle where the core structure remains permanent while wear-elements are maintained
. The project is exemplary as it moves beyond mere "impact reduction" toward circularity and resource optimization
. It proves that high-performance architecture can be achieved with a low initial investment (€13,000–14,000) by prioritizing durability, repairability, and material reuse
. By repurposing end-of-life fabrics into festival furniture, the project effectively "closes the loop".

The project focuses on technical empowerment and knowledge transfer within the festival’s operational community
. During the initial implementation in 2018, the Boom Festival’s production team, specifically the lead rigger, was actively involved in a hands-on training process
. Their role evolved from assisting in the first assembly to becoming autonomous managers of the structure
. This participatory approach allowed the local team to independently coordinate the re-mounting of the pavilion in 2022, 2023, and 2025 without the original designer’s presence
. By providing detailed plans for anchoring and cable diagrams, the project enabled the community to self-govern the maintenance and lifecycle of a complex architectural asset
. The impact of this involvement is a significant reduction in logistical costs and a sense of collective ownership over the pavilion’s success, which has become a staple of the festival’s landscape
. For the 2,000+ daily participants who benefit from the space, the pavilion offers an inclusive, barrier-free environment that enhances their physical well-being through superior thermal comfort.

The Golden Spiral Pavilion demonstrates an effective place-based approach that connects individual innovation with large-scale cultural ecosystems
. At the local/event level, the project involved a deep collaboration with the Boom Festival in Idanha-a-Nova, which provided the institutional support and the physical "living lab" to test the structure’s bioclimatic efficiency
. This engagement added value by validating the design’s circularity within a world-renowned sustainable environment (Boom’s Greener Festival context)
. At the national and European levels, the project reflects the mobility of expertise, as the designer (a Brazilian-Spanish national) implemented a solution in Portugal that addresses transnational climate challenges like extreme summer heat
. The added value of this multilevel engagement is the creation of a replicable blueprint for sustainable event infrastructure that can be scaled to other European regions or global contexts facing similar heatwaves
. The synergy between a specialized designer and a major European cultural organization has transformed a temporary installation into a permanent regional asset with over 10 years of lifespan.

The project is a testament to the integration of diverse fields to solve complex environmental and aesthetic challenges
. It merges Mathematics and Art by using the Golden Spiral (Fibonacci sequence) as the technical foundation for its form and color gradient, creating a harmonious sensory experience
. Engineering and Architecture were critical in developing the structural integrity of the large-span, open-air structure through a sophisticated galvanized steel cable-tension system
. The field of Environmental Sciences informed the bioclimatic design, which utilizes passive cooling strategies like natural convection and cross-shading to manage 40°C+ temperatures
. Furthermore, Textile Design and Material Science were essential in selecting and arranging recycled polyamide fabrics to optimize both durability and circularity
. Finally, the project reflects a deep understanding of Logistics and Event Production through its "design-for-disassembly" methodology, ensuring that technical complexity does not hinder the ease of re-mounting by non-specialist teams
. This transdisciplinary synergy allows the pavilion to function as a "cultural vehicle" that educates the public on sustainability while providing functional excellence.

The business model of the Golden Spiral Pavilion is based on value creation through innovation, longevity, and resource optimization
. Rather than a single-use expense, the structure is a long-term circular asset. The initial investment in 2018 (approximately €13,500–14,000) covered high-quality specialized materials—such as galvanized steel cables and a robust recycled wooden post—and the design expertise
. The project’s financial sustainability is demonstrated by its exceptionally low operational costs over an 8-year period. By implementing a 'Design for Disassembly' methodology and conducting successful knowledge transfer to the festival’s local production team, the need for recurring expert fees has been eliminated. This represents a disruptive innovation in the field: the designer has effectively become redundant, empowering the local community to take full agency over the infrastructure’s lifecycle. The core structure has a proven lifespan of 10+ years, making the cost per use significantly lower than procuring or renting standard temporary structures.
Furthermore, the project practices material circularity to reduce maintenance costs; for instance, end-of-life fabrics from the 2023 replacement were repurposed into festival furniture (puffs and small shades), extracting maximum value from every resource
. This model creates a positive brand image for the client (Boom Festival) and serves as a proof-of-concept for cost-effective, bioclimatic infrastructure that can be amortized over decades
