5 key facts about this project
01
Elevated cabins designed for treks incorporate floating platforms to minimize land disruption.
02
Incorporate charred wooden shingles for enhanced durability and a unique aesthetic.
03
Optimized for natural ventilation through extensive screening and strategic openings.
04

05
Each cabin type corresponds to a classical element, creating a cohesive environmental experience.

### Project Overview

The initiative, designed for the Ramblers Association, is situated in a rural landscape between Mewla and Vensplis, spanning approximately seventy miles. It incorporates a series of cabins that support an immersive experience for trekkers, emphasizing the integration of leisure, exploration, and nature. Each cabin embodies one of the classical elements—Earth, Air, Fire, and Water—offering distinct interactions with the environment while adhering to sustainable design principles.

### Site and Context

The strategic placement of cabins approximately every two miles along established hiking pathways enhances accessibility for users. The topography of the site informs design decisions, allowing each structure to integrate with natural features. This alignment with the landscape considers both the visual and functional aspects, ensuring that cabin placements encourage exploration and interaction with the surrounding environment.

### Design and Materiality

Each cabin is specifically designed to reflect its elemental inspiration, facilitating a unique user experience that engages with nature.

- **Earth Cabin**: Characterized by a sloped roof and large screened openings, this cabin promotes natural airflow and interaction with the changing seasons. Constructed with wood and insulated materials, it emphasizes thermal efficiency while harmonizing with the earth.

- **Air Cabin**: Featuring lightweight structural components and semi-permeable walls crafted from tensile fabrics, this cabin optimizes breeziness and minimizes visual disruption within the canopy.

- **Fire Cabin**: Designed around a central communal fire pit, its steeply pitched roof fosters socialization and warmth. Timber and metal are employed to ensure durability against natural elements.

- **Water Cabin**: Elevated on a floating platform, this cabin offers expansive views and abundant natural light. The use of waterproof materials ensures structural integrity and adaptability to its aquatic setting.

This careful material selection throughout the project emphasizes sustainability by utilizing renewable resources and minimizing environmental impact, while enhancing user comfort and functionality.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
