The Iceland Cave Tower features a unique design that stands out in its natural setting. Situated in an open landscape, it serves multiple functions, including an observation point, exhibition area, tourist information center, and café. The design prioritizes accessibility and comfort, allowing visitors to interact with both the structure and its surroundings.

Material Choices

Wood and steel are key materials in the tower's construction. Wood adds warmth and a natural feel, while steel provides the necessary strength to support the design. Together, they create a sturdy yet inviting space that aligns with the project's focus on sustainability. The combination of these materials helps to facilitate a design that is both functional and visually appealing.

Visitor Experience

The layout encourages visitors to journey upward through the building. Each level offers small exhibition spaces and scenic views, allowing guests to pause and enjoy their surroundings. This vertical progression creates a connection with the landscape. Each landing provides a moment for reflection and appreciation of the natural beauty outside.

Sustainability Measures

Sustainability is an important aspect of the tower's design. The compact shape and efficient use of energy are essential features. A system that manages water collection, heating, and energy use is integrated into the structure. Renewable energy sources, such as wind and solar power, are also considered to meet the building's energy needs.

Design Integration

The tower is intended as a temporary structure, which reduces its impact on the environment. This choice emphasizes the building's relationship with the landscape, blending its form with natural features. The careful proportions and inclusion of rainwater collection systems highlight a commitment to eco-friendliness, creating a space that interacts thoughtfully with its surroundings. Each design detail serves to enhance the functional and aesthetic qualities, establishing a clear connection to nature.

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.
