## Myvatn Cavern Architectural Design Project

The Myvatn Cavern is located near Lake Myvatn in Iceland and is designed to harmonize with the surrounding natural landscape while facilitating community engagement. The intent is to create communal spaces that promote interaction between people and their environment, with a strong focus on sustainability and ecological balance. The design concept is formulated as "double-folded," representing both a shelter for diverse species and a regenerative approach to the local ecosystem.

### Spatial Dynamics and User Interaction

The layout features a labyrinthine design that encourages exploration and social engagement. Key spatial elements include geothermal pools offering immersive experiences with the natural environment, as well as communal areas designed to facilitate varied activities. These spaces allow for unobstructed views of the landscape, reinforcing the connection between the interior and exterior. Additionally, green roofs serve dual purposes: they contribute to building insulation and promote local biodiversity.

### Material Innovation and Environmental Integration

Incorporating sustainable practices, the Myvatn Cavern utilizes materials such as Magnesium Oxide for soil stabilization, recycled wood from existing structures, glass for transparency and interaction with the outdoors, and locally sourced stones for structural integrity. The integration of vegetation into the design not only enhances aesthetic appeal but also supports ecological health. The building harnesses geothermal energy to optimize its energy usage, tapping into Iceland's abundant renewable resources while minimizing environmental impact.

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.
