### Overview

Located in the Krafla volcanic area of Iceland, the Long House spans 223 square meters and is designed to serve both local residents and tourists engaging in recreational activities such as skiing. The project seeks to balance functionality with an homage to the cultural heritage of Iceland, particularly the traditional Viking Long House. The facility is intended as a multifunctional ski cabin that provides a warming shelter for skiers, while also fostering a sense of community through the integration of shared and private spaces.

### Spatial Organization and User Experience

The interior layout is strategically divided into distinct programmatic zones that include a changing area, a ski tuning station, and equipment storage. This organization facilitates seamless transitions for users moving from skiing to relaxation, ensuring that shared areas enhance social interactions among guests. The design also prioritizes views of the Krafla crater, allowing visitors to remain connected to the surrounding landscape while enjoying the comfort of the cabin.

### Material Selection and Sustainability

A diverse array of materials has been employed to reflect the site's rugged environment and promote sustainability. The principal components include:

- **Concrete**: Used for structural elements, providing thermal mass and durability.
- **Wood**: Incorporated in internal finishes to add warmth and comfort.
- **Aluminum**: Featured in window systems to maximize natural light while ensuring energy efficiency.
- **Metal Roofing**: Utilized for its durability and visual coherence with the landscape.
- **Geothermal Systems**: Integrated for heating, leveraging local energy sources for efficiency.
- **Thermal Insulation**: Applied to enhance energy conservation and maintain comfort despite external climatic challenges.

This careful selection of materials aligns with Iceland's ecological principles, foster structural integrity, and create an aesthetic that complements the natural environment. An emphasis on renewable resources and innovative insulation techniques further underscores the project's commitment to sustainability while allowing for flexibility and potential future expansions.

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.
