## Architectural Design Report: Glacier Slopes

### Overview

Located near Myvatn Lake and the Krafla Caldera in Iceland, the Glacier Slopes project aims to provide a year-round sanctuary that balances relaxation with modern comforts. The design is intended to integrate into the Icelandic landscape while addressing environmental challenges, allowing both locals and visitors to connect with nature. The architecture promotes an experience of seasonal beauty, adapting to the stark winters and lush summers characteristic of the region.

### Layout and Functionality

At the project's core is a circular main room, designed as a central gathering space that optimally utilizes panoramic views. The spatial configuration includes an entrance, the main communal area, a garden to enhance natural connection, a viewing deck for outdoor engagement, and offices equipped for accessibility. This arrangement supports fluid circulation and visual coherence with the surrounding landscape, aligning with the site’s natural topography.

### Sustainable Practices

The project emphasizes sustainability through the integration of geothermal energy and thoughtful design strategies aimed at minimizing environmental impact. Features such as a double-skin façade enhance thermal efficiency while facilitating visual interaction with the landscape. The design also incorporates thermal dynamics, leveraging a heating system sourced from a nearby thermal river. Seasonal adaptability is further highlighted by elements like generous windows and a viewing deck, enabling occupants to enjoy the Northern Lights in winter and vibrant summer blooms.

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.
