El Pesar del Viento Pavilion by Álvaro Parraguez + Beatriz Harriet

A Performative Wind Pavilion Rooted in Antofagasta's Ruinas de Huanchaca

In the heart of Antofagasta, Chile, nestled within the evocative landscape of the Ruinas de Huanchaca Park, architects Álvaro Parraguez and Beatriz Harriet have crafted a dynamic spatial installation titled El Pesar del Viento as part of the YAF_Constructo 2 series. This temporary pavilion, spanning 144 m², is not merely an architectural structure—it is a sensory and performative space, continuously redefined by the natural and cultural forces that surround it.

A Phenomenological Dialogue Between Wind, Space, and Time

Conceived as an interactive and empirical artifact, the pavilion responds directly to the unique climatic, physical, and social context of its site. The structure is formed by a thick, four-meter-wide permeable perimeter that remains open on all sides—an intentional gesture to invite environmental elements and human interaction to shape its behavior.

At its core, the pavilion is self-supporting, yet ever-changing. From the structure’s edges, hundreds of suspended wooden fibers cascade downward, reacting to wind, temperature, and the subtle motion of visitors. As these fibers sway and vibrate, they produce an ephemeral "sky of shadows" where no ceiling exists, casting fragmented light and creating a sonic atmosphere that is at once dry, rough, and alive.

Structure, Materiality, and Movement in Symbiosis

From a spatial perspective, El Pesar del Viento is designed to liberate its center—an introspective void that invites contemplation and physical immersion. The fragile yet intentional structure rises delicately from the ground, mindful not to disturb the historical terrain. This floorless experience evokes the presence of gravity, weight, light, and darkness—all choreographed by the slow, clumsy, or even unconscious movements of its visitors.

Wood serves as the principal material, chosen not only for its expressive warmth but for its transformative nature. It bends, warps, creaks, and adjusts over time due to forces such as wind, humidity, heat, and human touch. This transformation is not seen as deterioration, but as a vital process of organic adaptation and material memory.

Construction Logic: Modular Rigidity and Hanging Narratives

The pavilion’s canopy, or “sky,” is constructed from a modular framework of eight wooden pillars supporting a woven grid of beams, held in tension with structural cables. These beams act as guidelines from which wooden elements are suspended—each piece destined to evolve with weather conditions, usage, and the passage of time.

This kinetic and temporal architecture tells a story of material agency and responsive design. It reclaims the value of slowness, of presence, and of environmental attunement in a world driven by permanence and speed.

Curated Installation at the Intersection of Architecture and Art

Curated by Benjamin Zapico, El Pesar del Viento exemplifies experimental architecture and site-specific installation at its most poetic. It challenges conventional ideas of enclosure, structure, and permanence, inviting users to reflect on their bodily engagement with space and nature.
