Subscribers only
Zinc-clad capsules with cross-laminated timber interiors create a harmonious blend of sustainability and comfort, offering an immersive lodging experience in the landscape of Iceland.
5 key facts about this project
01
Zinc cladding reflects the surrounding landscape for reduced visual impact.
02
Capsules utilize triple-glazed windows for enhanced insulation against Icelandic weather.
03
Cross-laminated timber panels provide structural strength while maintaining a low carbon footprint.
04
Modular design allows for relocation, adapting to varying environmental conditions.
05
Integrated rainwater collection systems promote sustainable resource management.

### Overview

Located in Iceland, near the Kiy Myvatn and Herðubreið volcanoes, the project introduces mobile hotel capsules designed as observatories for guests, aligning the built environment with the natural landscape. The intent of the design is to create a facility that enhances the surrounding beauty while adhering to principles of sustainability and ecological integration.

### Spatial Strategy and User Experience

The design incorporates a flexible internal layout that optimizes space efficiency, featuring multi-functional furniture that serves as sleeping and observation areas. Each capsule is equipped with natural ventilation systems to improve air circulation, reducing reliance on mechanical cooling. Additionally, integrated technologies, including geothermal heating and solar panels, facilitate energy efficiency throughout the facility.

### Material Considerations and Sustainability

Material selection is paramount to ensure both aesthetic integration and environmental responsibility. The structure utilizes zinc-polished cladding for its reflective qualities and durability, while triple-glazed windows provide thermal efficiency without sacrificing natural light. The use of recyclable galvanized steel for the framework, along with clay for thermal mass and cross-laminated timber for structural performance, underscores a commitment to sustainable building practices. Rainwater collection tanks further reinforce the project's ecological approach, highlighting its role as a model for responsible tourism development.

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.
