Designed by Javier Mera Luna in collaboration with Lesly Villagrán and María Beatriz Moncayo, "Arrachay 01" is a 25-square-meter workspace cabin perched over 4,000 meters above sea level in the Andes Mountains of Ecuador. Completed in 2020, the project was conceived as an auto-commissioned "workation" retreat to challenge new ways of working remotely in a stunning natural setting. The name "Arrachay" is a playful nod to the local Quichua language, combining achachay ("very cold") and arrarray ("very hot," referencing nearby thermal pools) to capture the contrast of the extreme mountain climate. The main architectural challenge was to create efficient insulation in the cold, high-altitude climate without relying on petroleum-based materials, which aligned with the architects' goal for a minimal carbon footprint. To achieve this, the team collaborated with YES Innovation to develop and utilize BIOM, a biosource insulation made from rice fibers. This innovative material repurposes agricultural waste from coastal communities in Ecuador, creating a circular economy. The BIOM insulation was hand-packed into the wooden perimeter structure and treated with a natural fire retardant, ensuring high thermal performance despite wide temperature variations. The use of bulk insulation also helps optimize on-site installation and prevent thermal bridging. The cabin’s timber structure is designed to be flexible and adaptive, blending harmoniously with the cloud-cloaked, mountainous landscape. A large window wall provides a visual connection to the breathtaking natural surroundings. The project embodies a philosophy of incorporating local technology and addressing environmental challenges through small-scale, thoughtful architecture.
