The Grjótagjá Tower stands in a unique geological location where the Eurasian and North American tectonic plates meet. This structure serves an important function as an observation tower and visitor center, designed to help people explore the stunning geothermal features and caves in the surrounding area. Taking inspiration from the natural landscape, the tower fits well within its rugged environment and invites visitors to enjoy a series of elevated viewpoints.

Architecture Concept

The design of the Grjótagjá Tower creates a connection between the building and the landscape. The roof resembles the shapes of tectonic plates rising from the earth, creating a continuous walkway along the fissure. This design encourages visitors to engage with their surroundings, allowing them to appreciate the unique geological formations from various angles.

Materials and Structure

The tower is built mostly from prefabricated concrete panels, which reflects a practical approach to construction in a remote area. These panels are organized in a grid layout, making on-site assembly easier while addressing transportation challenges. The structure is supported by pad foundations that help limit environmental disruption. Concrete columns provide stability without dominating the visual landscape.

Interior Spaces

Inside, the lobby and cafe areas reflect the rough and natural characteristics of the nearby terrain. The curved ceilings evoke the shapes found in caves, creating an inviting atmosphere that ties the interior to the building's external environment. This careful design enhances the visitor experience and reinforces the connection between the building and the landscape.

Geothermal Integration

Geothermal systems are a key feature of the tower, serving multiple functions while promoting sustainability. These systems provide electricity and warm water, while steam rising from the building adds a unique visual element. This steam complements the overall design and strengthens the connection between the architecture and the geothermal activity present in the area. Visitors experience a tangible link to the natural forces that shape the environment around them.

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.
