The Mývatn Green Shelter is located in Iceland on a hill that overlooks the Hverfjall volcano and the milky blue waters of the Mývatn Nature Baths. Designed as a greenhouse, it emphasizes a connection to the natural landscape while providing a comfortable space for visitors to enjoy. The design focuses on harmony with the site and the use of natural light, creating a welcoming atmosphere for both people and plants.

Architecture Concept

The design responds directly to the local topography, allowing the building to integrate into the landscape. Varying heights throughout the structure create a fluid form that mirrors the contours of the land. Visitors are guided by the architecture to appreciate both the building and the dramatic natural features surrounding it.

Materiality

Material choices are practical and functional, enhancing the shelter’s purpose. The upper part of the building uses wood and glass, promoting visibility and creating a connection with nature. Light pours in through these materials, supporting plant growth inside and giving the space a warm feel. A black metal base grounds the structure in the volcanic soil, connecting it firmly to its setting.

User Experience

The Mývatn Green Shelter offers more than just a greenhouse. Concrete walls and floors create an experience similar to walking through natural terrain. Outdoor spaces invite interaction, including a stairway that leads to a viewpoint, allowing visitors to take in expansive scenery. Each element encourages connection with the magnificent landscape.

Design Detail

A key feature of the shelter is its ability to grow local produce and prepare meals from those ingredients. This practical aspect deepens the relationship between visitors and the local environment. The combination of bright lighting, flourishing plants, and sweeping views fosters a unique space that celebrates the natural beauty of Iceland.

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.
