### Project Overview

Located in Iceland's rugged terrain, LightCab is designed as a transitional cabin to meet the needs of trekkers navigating this diverse landscape. The structure aims to provide shelter and essential amenities while harmonizing with the surrounding environment. Influenced by the concept of “following the light,” the design reinforces notions of connection and safety for those in remote areas.

### Spatial Strategy and User Experience

The architectural layout is composed of three distinct levels, each serving a specific purpose. The ground level presents a covered entry with technical facilities and essential amenities, such as storage and restrooms. The first level features dormitory accommodations for up to ten individuals, incorporating integrated showers and lockers tailored to the needs of outdoor enthusiasts. The upper level consists of a communal area designed for relaxation and nourishment, characterized by a kitchen and dining space complemented by panoramic windows that enhance the connection to the natural surroundings.

### Materiality and Sustainability

LightCab incorporates a selection of environmentally friendly materials to ensure durability and energy efficiency. The façade is clad in polished aluminum, which not only offers resilience but also reflects the local landscape, aiding in camouflage. Insulation panels made from PIR (polyisocyanurate) deliver thermal efficiency critical for the region's variable climate, while the warm pine wood interior enhances user comfort. Additionally, powder-coated aluminum window frames optimize natural light and provide expansive views. The design includes water collection systems and integrates renewable energy solutions, such as solar and wind, reinforcing the project’s commitment to sustainability and minimal environmental impact.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
