Sustainable Pavilion Design in Chile: Guillermo Hevia García's Inverted Dome

Architecture Meets Environmental Activism

Set in the picturesque surroundings of Ranco Lake, Chile, Guillermo Hevia García’s Inverted Dome Pavilion is a groundbreaking architectural installation. Created for a music festival in a public park, the pavilion addresses one of the most pressing environmental challenges: oceanic plastic pollution. Its innovative design not only captivates visually but also raises awareness of the need for sustainability and responsible consumption. 

Design Concept: The Inverted Dome as a Symbol

Raising Awareness Through Raw Presentation

The pavilion takes an unconventional approach by displaying oceanic plastic waste in its unprocessed state. Suspended within a transparent inverted dome, the garbage reflects the alarming reality of pollution, serving as a visual metaphor for the growing "islands" of waste in the sea.

The Inverted Dome’s Unique Form

The dome’s inverted structure is both functional and symbolic:

• Visual Focus: The downward curve creates an enclosed space beneath, drawing viewers to engage with the issue of waste.
• Structural Efficiency: The circular form ensures even weight distribution, enabling the structure to support the suspended debris effectively.

A Sustainable Approach to Pavilion Design

Modular and Portable Construction

Inspired by the wooden piers commonly found along coastlines, the pavilion’s structure is composed of repeating wooden sections. This modular system ensures:

• Ease of Assembly and Disassembly: The structure can be moved and reused in different locations without generating additional waste.
• Sustainable Materials: The use of wood emphasizes eco-friendly construction, aligning with the installation’s environmental message.

Circular Economy in Design

The pavilion avoids single-use construction by integrating elements that can be repurposed. This reduces its carbon footprint and sets a precedent for future temporary installations.

Community Engagement: A Space for Reflection

Interactive Perimeter Design

The pavilion’s circular wooden perimeter serves as more than just structural support. Visitors can:

• Sit and rest on the edges.
• Walk along the structure, experiencing the installation from different perspectives.

Gathering Space Under the Dome

Beneath the dome lies a communal area designed for interaction, contemplation, and discussion. This space provides a venue for festival-goers to reflect on the urgent need for environmental action.

Architectural Efficiency in Open Spaces

Circular Design Advantages

The circular plan enhances the pavilion’s functionality and aesthetic appeal:

• 360-Degree Visibility: The design looks identical from all angles, making it adaptable to various park layouts.
• Symbolic Significance: The circle reflects themes of unity and sustainability, reinforcing the pavilion’s environmental message.

A Landmark in Public Parks

The structure’s distinctive design ensures it stands out in its natural setting, creating a memorable visual experience while delivering a strong message about the consequences of pollution.

Conclusion: A Blueprint for Sustainable Pavilion Design

Guillermo Hevia García’s Inverted Dome Pavilion is a testament to the potential of architecture to inspire social and environmental change. By combining sustainable construction with a powerful narrative, the pavilion challenges visitors to confront the reality of plastic pollution and reconsider their relationship with disposable materials.

This innovative installation demonstrates that architecture can transcend traditional boundaries, becoming a medium for awareness and advocacy. It sets a new standard for sustainable pavilion design in Chile and beyond, proving that even temporary structures can have a lasting impact on society.
