The Grjótagjá Observatory is located at the meeting point of the North American and Eurasian tectonic plates in Iceland. It serves as a space for exploration and engagement, allowing visitors to appreciate the striking geological landscape. The design focuses on the theme of connection and separation, inviting users to interact with the natural environment through structured pathways and observation points.

Concept and Design

The design reflects the idea of an arch that connects the two continents. This representation encourages visitors to experience the earth's geological features in a tactile way. The space is not only for observation but also for movement and exploration, leading users on a journey through the unique landscape.

Pathway Organization

Visitors follow a series of pathways that act as links between various facilities. These include public caves, a lobby, a café, toilets, and the main observatory area. The careful arrangement of these spaces enhances the overall experience, providing clear access and encouraging exploration while maintaining connections among different areas.

Materiality and Sustainability

The structure is built using raw materials that resonate with the surrounding environment. Steel beams and poles form the main framework, while the outer skin comprises four layers of reinforcing bars. This simple yet effective choice promotes durability and stability. Additionally, the design includes a water collection system within the poles, emphasizing a commitment to sustainability and responsible resource use.

Spatial Dynamics

Spaces within the observatory encompass both public areas and private retreats. Paths lead to quiet private baths, allowing visitors to choose their level of engagement. This thoughtful design encourages a variety of experiences and interactions. The emphasis on movement invites exploration while deepening the connection to the natural world.

The observatory’s panoramic viewpoint is reached by an ascending staircase, offering visitors a full view of the surrounding landscape, reinforcing the relationship between people and the powerful geological forces at play in this remarkable location.

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.
