05
Outer layer inspired by cell structures, promoting environmental resilience.

The Monarch Pavilion, located in the Atacama Desert, combines artistic expression with practical use. Inspired by the butterfly, the structure captures both its delicate appearance and symbolic significance. Designed to function as a contemplative space, it emphasizes openness and encourages a connection with the surrounding environment.

Design Concept and Form

The form of the Monarch Pavilion mimics the wings of a butterfly, with a layout that is intentionally symmetrical. Each side of the pavilion includes a room of 49.8 square meters. This symmetry not only enhances the visual appeal but also supports a fluid interaction among the interior spaces, creating a sense of balance throughout.

Structural System

The pavilion's core consists of a monolithic system, utilizing plaited hazelnut twigs that are encased in a mixture of clay and sand-lime brick. This choice of materials contributes to the strength of the structure and reflects an emphasis on using local resources. Clay is adaptable and helps maintain comfortable temperatures in the warm desert climate, while sand-lime brick adds durability to the outer layer.

Environmental Considerations

The outer layer of the pavilion is designed to shield the internal structure from the harsh elements of the environment. Drawing inspiration from natural cell structures, this layer enhances the structure's ecological performance, connecting it effectively to the desert landscape. This thoughtful approach ensures that the pavilion is not only resilient but also engaging with its surroundings.

Artistic Expression

The Monarch Pavilion expresses a narrative that celebrates the butterfly, fostering awareness about nature and its conservation. The integration of design and environment is deliberate, offering an architectural experience that resonates with its setting. Light and shadow play across the surfaces, reflecting the gentle movement of a butterfly in flight, further enhancing the visual experience of the space.
