### Project Overview

The ski cabin located in Krafla, Iceland, utilizes architectural design principles that reflect and integrate with the surrounding volcanic landscape, particularly drawing inspiration from the region's characteristic basalt formations. It serves as a retreat for ski enthusiasts while prioritizing modern comfort and sustainable practices. Positioned within a geothermal area known for its stunning scenery, the cabin is designed to enhance both functionality and visual appeal.

### Morphological Influence

The architectural form embodies the verticality and geometric characteristics of basalt columns, resembling the natural contours of the topography. The fluid, organic shape of the structure echoes the undulating lines of the nearby landscape, creating a visual connection with the environment. The design intentionally engages with the existing terrain to foster a sense of belonging between the cabin and its geological context.

### Material Selection and Sustainability

Local materials play a crucial role in the cabin's construction, emphasizing sustainability and environmental harmony:

- **Basalt Columns**: Used as the primary structural support, these locally sourced elements provide both aesthetic value and functional integrity.
- **Basalt Wall Panels**: Curved panels enhance the thermal insulation and overall energy efficiency of the building while providing continuity between interior and exterior spaces.
- **Steel Framework**: This component ensures robust structural stability and allows for necessary thermal expansion.
- **High-Performance Glazing**: Expansive windows invite natural light and offer panoramic views, enhancing the connection to the landscape while maintaining energy efficiency.

The incorporation of geothermal heating systems demonstrates a commitment to eco-friendly practices, harnessing local energy resources to regulate indoor climates.

### Functional Organization

The cabin features carefully designated areas that cater to both recreational and practical needs:

- **Rest Zones**: Adjacent to the skiing area, these spaces are designed for relaxation and recovery after outdoor activities.
- **Educational Information Point**: This area informs visitors about local ecology and provides relevant skiing insights.
- **Maintenance Facilities**: Including a dedicated garage for snow grooming equipment to support ongoing operations.
- **Viewing Deck**: Designed to maximize the experience of the surrounding natural beauty, providing a space for contemplation and connection with the environment.

The architectural design thus encapsulates a blend of comfort, utility, and ecological mindfulness, reflecting a deliberate approach to responsible construction practices and community engagement.

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.
