Plaza Alfonso de Salazar
2025

As part of the Concéntrico Festival, this temporary stage for experimentation functions as a space for preparing the reuse of materials from deconstructed pavilions. It anticipates next year’s construction of a new pavilion made entirely from reused components: plywood, wooden beams, thermo bricks, textiles, and more.

Throughout the week, the space transforms into an in-situ workshop, a shared stage for reflection, fabrication, and conversation. Public interviews with pavilion designers are hosted to discuss the future potential of reuse and rethink the afterlife of temporary architecture.

Part material archive, part exhibition, part collective studio, this space offers visitors a behind-the-scenes look into circular design processes: measuring components, creating a material database, and sketching early ideas. Drawings are pinned to the walls, fragments of reused materials are on display, and ideas flow freely.

A magasin d’idées, a pop-up scene of reuse, sheltered against a wall — this is a space to gather, to imagine, and to build the future from what remains.

Architecturally, the space is made entirely from construction site materials, simply assembled using cargo straps. Everything rests on wooden supports, gently lifting the structure off the ground — marking it as temporary, deliberate, and adaptable.

Lego-style concrete blocks form walls and display surfaces. Visible, essential orange cargo straps tie the elements together, celebrating a language of tension, reuse, and temporary assemblies. Round metal tubes or wooden poles span overhead, stabilized by rubble or stone. A simple orange tarp stretches across the top, casting shade and giving the space a distinct identity.

Together, these raw materials shape a flexible public space: a stage for conversation, a workspace for drawing and documentation, and a physical manifesto for circular architecture.

ACTE studio

Founded in 2020 by Estelle Barriol and joined in 2023 by Fanny Bordes, their work focuses on the reuse of materials as a theoretical and practical component. Inspired by vernacular techniques, the studio uses a low-tech approach based on geo- and bio-sourced resources. Through a Design-Build process, it creates accessible, resilient and generous spaces, challenging aesthetic conventions and promoting responsible, resource-conscious architecture.
