05
Design integrates educational aspects of geology and nature.

The Iceland Cave Tower is located just north of Hverfjall volcano in Iceland, sitting at the point where the Eurasian and North American tectonic plates converge. This site serves both an educational and recreational purpose. The design aims to celebrate the merging of these continents while respecting and minimizing impact on the natural landscape.

Design Concept

The building's form serves as a visual marker in the rugged landscape. Visitors are welcomed by an elevated boardwalk that connects the two tectonic plates, providing a way to experience the geological features up close. As people walk along this path, they gain a deeper understanding of the landscape and its unique geology.

Interior Experience

Inside the tower, a spiral staircase wraps around a central core, guiding visitors upwards. The design includes resting areas on the way up, allowing individuals to pause and take in the view. At the top, the opening offers expansive views of the tectonic plates, the striking Hverfjall volcano, and the mesmerizing Aurora Borealis, enhancing the overall experience of the space.

Material Use

Charcoal wood cladding is used for both the tower and the welcome center. This choice of material creates a visual connection with the surrounding volcanic rock. The dark wood contrasts with the bright winter landscape, helping the structures blend into their surroundings, while still standing out as architectural features.

Spatial Integration

The design divides the structure into two main parts: one dedicated to the observation tower and the other serving additional program needs. This arrangement allows for a thoughtful connection between the two tectonic plates. Lookout points are positioned to provide wide views, focusing attention on the remarkable geological features that surround the site. Each window frames a view, inviting visitors to engage with the stunning Icelandic landscape.

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.
