Clad in local basalt and oriented along cardinal directions, the viewing tower offers visitors expansive views of Iceland's tectonic divide while promoting an immersive connection with the surrounding geothermal landscape.
5 key facts about this project
01
Clad in basalt, the structure harmonizes with the surrounding geology.
02
The tower is oriented along cardinal directions to enhance viewing experiences.
03
Access points are designed to flow seamlessly between built and natural environments.
04
Vertical design encourages elevation and exploration of the landscape.
05
Openings in the upper level frame significant views of the tectonic divide.

Grjótagjá: Reconfiguring a Geometry is located in the geothermal landscape of Grjótagjá, Iceland. The design aims to create a landmark that interacts with its natural surroundings while serving a functional purpose. Through a clear geometric concept, characterized by simple forms and noticeable height, the architecture stands out against the rolling terrain of the area.

Geometric Arrangement

The building is organized along the four cardinal directions—North, South, East, and West. This specific layout enhances the connection between the structure and the landscape. Openings in the tower allow visitors to take in views of important natural features, especially the tectonic divide. The organization results in a visual conversation between the constructed spaces and the surrounding geological context.

Vertical Experience

The design emphasizes verticality, creating a viewing tower that rises above its surroundings. This height encourages exploration and offers various perspectives for those who visit. As individuals ascend through the different levels, they gain access to the raised walkway at level one, promoting an easy flow through the building.

Material Contextuality

The materials used in the project are key in reinforcing ties to the site. The viewing tower and its accompanying buildings are clad in basalt, aligning them with the geological characteristics of Grjótagjá. This use of local stone helps to blend the structures into the natural environment, providing a strong sense of place.

Visitor Engagement

The design considers how visitors will interact with both the building and the landscape. At the café and information center, people can gather details and plan their visits. A clear path from the structured areas to the natural caves supports a natural transition between built and unbuilt spaces. A linear layout draws attention to the surrounding views and emphasizes the relationship between movement and observation within the landscape.

From the uppermost level, large openings in the tower allow light to enter and provide wide views of the area below. This interplay of light and structure enhances the experience for visitors, encouraging them to reflect on the natural beauty surrounding Grjótagjá.

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.
