The Steinar Grjótagjá Gestahús project is located in Iceland, at the Grjótagjá caves where the European and American tectonic plates meet. This site serves as a gathering place for visitors, providing a space that promotes connection with the remarkable natural landscape. The design centers around establishing links between the two tectonic plates through carefully arranged structures that enhance the experience of the unique geological context of the area.

Guesthouse

The guesthouse sits on the European plate and acts as the heart of visitor interaction. Its insulated design offers both comfort and hospitality, with spaces that encourage social engagement. A prominent feature is the fireplace, which invites communal activities and shared moments. The overall atmosphere prioritizes warmth, making it a welcoming space for guests.

Observation Deck

Next to the guesthouse is an observation deck that transitions visitors from indoors to the vastness of the outdoors. This platform provides an opportunity to take in rich views of the surrounding landscape. It also marks the beginning of the bridge that connects to another structure, emphasizing its functionality in linking visitors to the broader environment.

Open Bridge

The open bridge is an important feature, allowing movement over the cave system's unique geological formations. It connects the European plate with the American plate and encourages guests to appreciate the geological details below. The design maximizes views, allowing visitors to experience the striking features of the caves and their surroundings.

Observation Tower

On the American plate, a 40-meter-tall observation tower offers an elevated perspective of the area. Visitors can climb to this tower for sweeping 360-degree views, with a warm booth at the top providing shelter. This space enhances the experience, allowing for comfortable observation of the breathtaking Icelandic landscape.

Locally sourced stone is used for the foundational pylons of the project, creating a strong connection to its rugged environment. These pylons not only provide structural support but also resonate with Iceland’s architectural heritage. The arrangement of spaces and choice of materials underscore the relationship between the built environment and nature, firmly rooting the structures within their geological setting.

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.
