The Tephra Cone is an architectural project located in north Iceland near Lake Myvatn, designed as a multifunctional space that integrates a coffee shop and information center. The building is situated in a region characterized by volcanic landscapes and geothermal features, creating a unique contextual backdrop. The architectural design aligns with its environment, emphasizing a connection to the natural terrain while providing visitors with an engaging experience.

The primary function of the Tephra Cone is to serve as a gathering place for tourists and locals, offering amenities that enhance the exploration of the surrounding volcanic geography. The structure invites interaction through its design, encouraging visitors to experience both the interior and the exterior landscapes. Its layout facilitates various activities, from casual dining to exhibitions, while maintaining a focus on the overall user experience within the distinct setting.

In terms of design, the Tephra Cone employs several noteworthy approaches that differentiate it from conventional architecture. The circular form of the building echoes the geological features of the area, specifically the volcanic cones that shape the landscape. This decision creates a seamless dialogue between the structure and its environment, reinforcing the narrative of place. The use of local materials is another vital aspect of the project. The timber frame construction and incorporation of lava aggregates in the concrete foundation not only ensure structural integrity but also reflect the characteristics of the surrounding environment, contributing to a sense of place.

The spatial organization within the Tephra Cone emphasizes transparency and openness, allowing natural light to filter into the interior while providing panoramic views of the external landscape. The integration of large glass windows blurs the boundary between inside and outside, inviting the landscape into the visitor's experience. Additionally, the design features varied heights and diameters, which creates dynamic spatial experiences that encourage exploration and interaction among users.

The incorporation of a courtyard area within the design encourages outdoor engagement, providing a setting for potential exhibitions while ensuring visitors can appreciate the natural beauty of the landscape. This outdoor space enhances the accessibility of the project, encouraging foot traffic and interaction between the building and its surroundings.

Overall, the Tephra Cone stands as a well-considered architectural project that respects and engages with its landscape. Its design reflects a commitment to sustainability, functionality, and interaction, making it a significant addition to the Icelandic region. For those interested in further understanding the architectural plans, sections, and unique design ideas, exploring the project presentation will provide deeper insights.

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.
