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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
