### Overview

Located in Iceland, the Slow Cabin design project serves as a refuge for trekkers traversing the challenging terrain of the region. The project is driven by a commitment to ensuring safety, comfort, and functionality in a harsh environment while facilitating a restorative experience for its occupants. The design integrates seamlessly with the natural landscape, drawing inspiration from the surrounding elements to provide essential services for transient individuals.

### Design and Spatial Strategy

The layout of the Slow Cabin is organized into five functional modules: Shelter, Water/Food, Heat, Rest, and Hygiene. Each module addresses specific human needs, prioritizing user experience in a remote setting. The shelter comprises a rustic wooden structure that provides insulation while fostering a warm atmosphere, utilizing locally sourced materials. The Water/Food section incorporates a kitchenette and water collection mechanisms that harness local resources, emphasizing sustainability. Geothermal heating is incorporated as a vital design element, serving both functional and aesthetic roles through exposed thermal pipes.

The sleeping quarters employ suspended platforms that maximize vertical space and storage availability, allowing for flexible occupancy arrangements. The hygiene facilities utilize composting toilets to minimize water usage while maintaining sanitation. By optimizing layout and functionality, the design encourages communal spaces that promote interaction among travelers.

### Material Choices

The material selection underscores a commitment to sustainability and environmental integration. Key components include:

- **Wood**: Serving as the primary structural material, it provides both insulation and an organic aesthetic.
- **Geothermal Heating Elements**: These durable thermal pipes feature an industrial design that contributes to the cabin's interior atmosphere.
- **Composting Toilets**: Constructed with sustainable materials, these systems are designed to reduce ecological impact.
- **Concrete**: Utilized in flooring and structural elements for durability against the Icelandic climate.
- **Glass**: Incorporated in windows to maximize natural light and views of the landscape.

The thoughtful material choices and innovative spatial strategies contribute to a cohesive design that meets the practical needs of occupants while aligning with ecological principles.

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.
