Story

Forestone Cabin

An experimental wooden dwelling in the Pyrenees

Forestone Cabin, a 20 m² experimental wooden dwelling, is situated in the Pyrenees at MónNatura Sort. Designed by IAAC's 2025 cohort of the Master in Ecological Architecture and Advanced Construction, the cabin is part of the Bio for Piri initiative, promoting the sustainable use of local timber from Pyrenean forests.

The cabin's sculptural form is inspired by the rocky terrain of the Pyrenees, appearing as a block of stone naturally resting on the site. Its faceted geometry, composed of inclined walls and a sloping roof, responds to programmatic needs, climatic conditions, and solar exposure. Carefully positioned openings frame views of the surrounding mountains and enable cross-ventilation, while operable wooden shutters ensure complete darkness at night, preventing light pollution.

The exterior façade is crafted from pine boards charred using the Japanese Yakisugi technique, enhancing durability and symbolizing fire management—an essential aspect of regenerative forestry in the region. Inside, custom-made CLT elements form an integrated wooden space, with furniture and structural components designed and fabricated by students.

The project emphasizes replicability, demonstrating how small-scale architecture can be sustainably built using local materials and low-impact methods. It serves as a prototype for forest habitation, aligning architectural production with environmental stewardship.

Design Highlights

  • Faceted geometry inspired by natural stone formations

  • Use of Yakisugi technique for durable, charred wood façade

  • Custom-made CLT elements for integrated interior space

  • Emphasis on local materials and craftsmanship

  • Adaptable, replicable design for sustainable forest habitation
