The Pillar of Cave is located in the Grjótagjá area of Iceland, known for its unique geological features and geothermal activity. The structure serves as a visitor center, enhancing access to nearby caves while protecting the fragile ecosystem of the Vogagjá cave. The overall design aims to blend naturally with the environment, encouraging visitors to engage with the surrounding landscape and the experience within.

Materiality and Sustainability

Solar panels are installed along the enclosing platform, generating renewable energy to power the facility. This choice showcases a commitment to sustainability, reducing the ecological impact while ensuring efficient energy use within the area. The project reflects modern environmental practices, positioning it as a responsible structure in a delicate ecological system.

Organic Form and Visitor Experience

The design of the Pillar draws inspiration from cave shapes, resulting in a form that offers a unique exploration experience. Visitors navigate through openings and curved walls, creating a sense of moving within a natural cave. This journey elevates the experience, allowing for varied views of the striking landscape from multiple heights.

Interior Irrigation System

Inside, a concrete frame supports an innovative irrigation system that supplies water to plants growing between active areas and platforms. This system enhances the indoor environment, promoting plant life that connects visitors to nature while supporting the project’s ecological goals.

The Pillar features an irregular façade with thoughtfully placed voids that reference cave openings. These gaps allow for natural light and ventilation, and can also lead to the appearance of seasonal features like waterfalls or icicles. Such details not only enrich the visual interest but also highlight the relationship between the structure and the changing natural environment.

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.
