The Iceland Volcano Coffee Shop is located at Hverfjall Volcano, a site known for its dramatic geological formations caused by the collision of tectonic plates. The structure serves as a café and an exhibition space, designed to reflect the natural environment while providing visitors with a unique experience. Its overall concept emphasizes fluid forms that engage with the surrounding landscape, allowing the building to coexist harmoniously with its natural setting.

Architectural Concept

The design incorporates two large, curved plates that rise from the ground, following the contours of the landscape. This choice of form contrasts with traditional straight lines and right angles, creating a more organic appearance. The plates overlap in certain areas, creating shaded spaces and inviting visitors to explore paths that meander through the site. This interaction between architecture and nature fosters a sense of connection with the volcanic environment.

Interior Layout

Inside, a continuous open space exists beneath the two plates, containing several functional areas within the coffee shop. The design naturally frames the entrance and lobby, letting visitors easily transition into the building. Concrete cores serve to define individual spaces such as the café, an exhibition area, an office, storage, and restrooms, while ensuring that these areas remain visually connected to each other. The layout encourages movement throughout the space, allowing for diverse user experiences.

Materiality and Craftsmanship

Concrete is the primary material for the structure, selected for its strength and relevance to the geological context of the site. The plates are created using wooden molds, shaped to mirror the natural formations of the surrounding landscape. This choice adds an element of craftsmanship to the project, highlighting a thoughtful approach to connecting the architecture with the volcanic environment.

Visitor Experience

The design enhances visitor interaction with features such as exhibition tables that allow for comfortable exploration of displays related to the volcano. The circular shape of the reception desk encourages engagement from all sides, while the café seating features long, flowing curves that promote social interaction. The interconnected layout allows guests to navigate freely, immersing them in a space that reflects the unique earth layers of Hverfjall.

Natural light flows through the interior, illuminating the concrete surfaces and enhancing the textures of the forms. This balance of light and shadow creates a welcoming atmosphere that invites visitors to appreciate the surroundings, emphasizing both the architecture and the remarkable volcanic landscape. The design provides not only a space for enjoyment but also a deeper connection to the natural world.

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.
