With a distinctive design of spherical lodgments enabled by mobility and polycarbonate skylights that enhance celestial views, this architectural endeavor offers visitors a unique experience of the northern lights while embracing geothermal sustainability.
5 key facts about this project
01
Spherical lodgments feature mobility systems allowing repositioning along dual tracks.
02
Construction utilizes reinforced concrete for structural stability and durability.
03
Polycarbonate skylights are designed for variable pitch, optimizing natural light and views.
04
Geothermal energy systems support sustainable heating throughout the structure.
05
The design uniquely integrates mythology with modern functionality for enhanced visitor engagement.

### Overview

Located near the Krafla volcano in Iceland, the project "Follow The Path to Aurorae" draws inspiration from the natural phenomena of the region, specifically the northern lights. The design aims to foster an immersive experience that connects visitors with the landscape and celestial elements. Utilizing the metaphor of the goddess Aurora and her journey from sea to sky, the architecture prompts engagement with the environment through a carefully crafted path that offers varied perspectives of the surrounding natural beauty.

### Spatial Configuration and Functionality

The layout consists of guest rooms strategically arranged along a winding path, facilitating movement and exploration. The accommodations vary in type—ranging from single to quadruple configurations—created by a zoning strategy that balances communal and private areas. Each room is thoughtfully positioned to maximize views of the aurora borealis, enhancing visitor experience through design that prioritizes sightlines and interaction with the sky.

### Material Characteristics and Energy Solutions

Utilizing an array of innovative materials, the design emphasizes both aesthetic appeal and functional integrity. The structural foundation consists of reinforced concrete for durability, while custom metal-framed skylights made from multiwall polycarbonate panels enhance natural light entry. Electronically tintable Sageglass windows offer adjustable transparency for occupant comfort and energy efficiency.

Sustainability is a focal point, incorporating geothermal energy from the Krafla resources for heating, rainwater harvesting systems for potable water, and a closed-loop wastewater treatment system to minimize environmental impact. The unique pathway dynamics feature spherical wheels beneath the guest rooms, permitting movement along dual tracks—both stationary lodging tracks and traversable movement pathways—reflecting the narrative of motion inherent in the concept.

`
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.
