An elongated structure of reinforced concrete spans a geological crack, integrating a modular pathway system that connects private and public cave environments, serving as an inviting visitor center in Iceland's unique landscape.
5 key facts about this project
01
An elongated form allows for panoramic views of the surrounding Icelandic landscape.
02
The modular pathway system is inspired by the flexibility of the human spine.
03
Uses reinforced concrete to navigate the geological challenges of the site.
04
Distinct separation between private and public areas enhances visitor experience.
05
Ascends to a higher viewpoint, acting as a bridge over the geological crack.

The project explores the connection between geological forces and human experiences within Iceland’s unique landscape. Located near the North American and Eurasian tectonic plates, it introduces the concept of the “PUZZLE.” This concept represents a way to bridge gaps created by geological movements. The building serves as a visitor center, linking the private Kvennagjá cave and the public Karlagjá caves, allowing visitors to engage closely with the natural surroundings.

Modular Path System

A modular path system is central to the design, inspired by the flexibility of the human spine. This design connects different components in a way that promotes movement. As visitors walk along the path, they navigate between different areas of the caves, experiencing the contrasting environments. The system not only guides individuals through the space but also fosters a stronger connection to the surrounding geology. This interactive quality makes the path an essential part of the overall design.

Spatial Organization

Inside the PUZZLE house, spaces are thoughtfully arranged to serve multiple functions while keeping a clear architectural identity. A main distribution point allows easy access to various areas, such as a café, an observation platform, and changing rooms. This layout effectively meets the needs of visitors. Distinct private and public zones enhance user experience, balancing openness with moments of quiet. The design encourages exploration and interaction throughout the building.

Building Form and Materiality

The building has an elongated form that visually connects with the Icelandic landscape. The generous heights provide broad views, linking the structure to its environment. Materials mentioned in the project include reinforced concrete for strength, elastomer bearings for flexibility, and load distribution plates for stability. These materials respond to the geological conditions, ensuring that the structure remains secure and resilient. They contribute to creating a respectful relationship with the surrounding land.

A distinctive staircase ascends to a higher level, designed as a bridge above the geological crack. This feature invites visitors to climb and enjoy unobstructed views of the landscape. Treated as an outdoor space, the staircase emphasizes the connection between people and nature. The integration of form, structure, and context supports a sense of discovery, making it an inviting place for interaction with Iceland’s remarkable geography.

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.
