The distinct crystalline roof constructed from GRC panels merges with Iceland's volcanic landscape, providing a functional retreat for winter sports enthusiasts.
5 key facts about this project
01
The roofing design emulates the form of natural ice crystals, enhancing aesthetic integration with the landscape.
02
Prefabricated GRC panels ensure structural durability while minimizing on-site construction time.
03
Large glazing elements maximize natural light and offer unobstructed views of the surrounding mountains.
04
Dedicated ski maintenance facilities support year-round recreational use and operational efficiency.
05
Incorporation of space frame trusses allows for flexible interior layouts while maintaining structural integrity.

### Project Overview

Located in the scenic landscapes of Iceland, the Ski Snow Cabin exhibits an architectural design that responds to the region’s unique climatic and geological attributes. This facility is intended to support winter sports enthusiasts by providing essential amenities, including relaxation areas, equipment storage, and viewing platforms, thereby enhancing the outdoor experience while integrating with the surrounding natural environment.

### Spatial Organization

The arrangement of spaces within the Snow Cabin is methodically designed to fulfill various user needs while ensuring an intuitive flow. The upper level features a central entrance that leads into distinct functional zones, including a relaxation area for skiers, a self-serve refreshment station, and an elevated viewing deck that provides panoramic vistas of the surrounding landscape. The lower level accommodates essential facilities such as unisex changing rooms, an equipment check and tuning station, and a garage for snow grooming vehicles, supporting the operational efficiency of the cabin while ensuring user comfort before and after skiing activities.

### Materiality and Structure

The use of materiality is a key focus within the design, with the roof constructed from prefabricated Glass Reinforced Concrete (GRC) panels that create a slope mimicking natural forms and facilitating efficient snow shedding. Large glazing panels are incorporated throughout, allowing natural light to permeate the interior while providing expansive views and maintaining thermal performance. The primary structural system employs space frame trusses, accommodating the sweeping curves of the design and enhancing aesthetic appeal without compromising structural integrity. This thoughtful integration of materials and design elements underscores a commitment to sustainability and connection with Iceland's geological features.

`
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.
