05
Innovative use of corten steel provides durability in harsh weather conditions.

The Iceland Cave Tower stands within the distinctive volcanic landscape of the Grjótagjá caves in Iceland. It serves as a space for visitors to observe and engage with the striking geological features of the area. The design concept revolves around the relationship between the structure and the environment, presenting a physical connection to the geological processes that have shaped this region.

Design Concept

The concept of the Iceland Cave Tower draws inspiration from the geological formations found in the area. The structure resembles a welding line, suggesting a connection between two land masses. A diagonal element is key to the design, highlighting the vertical nature of the geological fault. This choice guides the attention of visitors toward the captivating landscape, making the experience of viewing the Mid-Atlantic Ridge more engaging.

Functionality and Visitor Experience

The layout incorporates various functional spaces that enhance the visitor experience. Features include observation platforms, a café, waiting areas, and changing rooms. This arrangement promotes smooth movement throughout the site, allowing people to easily navigate between different areas. Public and private trails lead visitors from parking spaces to the main entrance, ensuring accessibility while respecting the natural contours of the land.

Sustainability Considerations

Sustainability is an important aspect of the design. An engine house, which focuses on managing water and energy, illustrates this commitment. It uses systems like biodigesters and geothermal energy solutions. By integrating these features, the design aims to minimize environmental impact, showcasing a responsible approach to architecture amidst nature.

Materials

The materials selected for the Iceland Cave Tower include basaltic concrete and laminated glass. These are chosen to blend with the surrounding landscape. In addition, permeable corten steel and a recycled aluminum structure support the project’s sustainable goals. The material choices reflect a focus on durability and environmental responsibility.

Large observation platforms provide expansive views of the surrounding geological formations, inviting visitors to appreciate the area's unique beauty.

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.
