05
Elevation changes create distinct visitor experiences throughout the space.

The Hverfjall Coffee House is located at the base of Hverfjall Volcano in the Mývatn region. It serves as a unique space for visitors to relax and enjoy the surrounding landscape. The design aims to connect the building with nature, enhancing the experience of being in this remarkable setting.

Architectural Concept

The form of the building features flowing shapes that draw the eye toward the volcano. This design choice encourages a visual connection with the landscape, allowing visitors to appreciate the scenery. The layout is planned to create an immersive experience, where the natural features of the area become an integral part of the visit.



Materiality

Basalt is used for both the inside and outside of the building. This choice of material reflects the volcanic nature of the region, reinforcing a strong connection to the landscape. Additionally, timber is used in the construction, contributing to a warm and inviting atmosphere throughout the interior. These materials work together to enhance the overall experience of the space.



Sustainability Features

Sustainability is an important aspect of the design. The building includes a green roof, which supports local plants and wildlife. This feature contributes to thermal insulation and helps manage rainwater. Large windows let in natural light, allowing passive solar heating to warm the space during colder months, making the interior more comfortable.



Visitor Experience

The layout guides visitors on a journey through the building. They move from the parking area to the entrance, then through an exhibition space before reaching the coffee shop. This progression creates distinct spaces that invite exploration. A roof that slopes upward culminates in a lookout point, providing an expansive view of the landscape and encouraging moments of appreciation for the natural surroundings.

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.
