Cross-laminated timber and tectonic fissures merge seamlessly in a visitor center designed to enhance the geological experience of the surrounding Icelandic landscape.
5 key facts about this project
01
Cross-laminated timber construction reduces carbon footprint while enhancing structural integrity.
02
The design incorporates natural light through a strategically placed vertical fissure.
03
A bent A-frame structure offers dynamic visual interest while blending with local topography.
04
Charred wooden shingles provide weather resistance and promote fire safety.
05
Visitor pathways are integrated to enhance exploration of the surrounding geological features.

The Shifting Tectonics: Iceland Cave Tower is a well-conceived architectural project designed as a visitor center and observation tower in close proximity to the Grjótagjá cave in Iceland. This project integrates into a landscape characterized by volcanic activity and tectonic shifts, reflecting those geological phenomena through its design and function. The tower serves two primary functions: providing an observation deck for panoramic views and offering educational space for visitor engagement regarding the unique geological features of the area.

Architecturally, the project features a dual form comprising a vertical tower and a surrounding earth mound that simulates the natural topography of the site. This integration respects and enhances the landscape while minimizing disruption. The use of cross-laminated timber for the main structure underscores a commitment to sustainability, pairing durability with reduced environmental impact. Concrete is employed for essential structural elements, while steel is utilized for connections and detailing to ensure stability. Aluminum coping is strategically integrated into the roof design, contributing to the building’s contemporary aesthetic.

The design approach emphasizes the dialogue between the structure and the landscape. The angular geometry of the tower mimics the tectonic shifts seen in the surrounding environment. A notable feature is the vertical fissure that allows natural light into the interior while also framing views of the landscape outside. This design choice enhances the visitor experience by providing dynamic sightlines and encourages engagement with the surroundings.

The pathway leading to the entrance is carefully curated to guide visitors through the site, offering various viewpoints and contemplation areas. Inside, the reception area welcomes visitors and serves as a transition zone into the expansive viewing platform above. The interiors are designed to accommodate a variety of functions including informational spaces about the unique geology of Iceland and relaxation zones that allow visitors to absorb the surrounding beauty.

The Shifting Tectonics: Iceland Cave Tower is differentiated from other architectural projects through its responsive design, which is closely linked to the landscape’s geological history. By focusing on materials conducive to the environment and integrating spatial dynamics that highlight both functionality and aesthetic appeal, the project creates a comprehensive experience for visitors.

To explore the architectural plans, architectural sections, architectural designs, and other architectural ideas that define this project, further details can enhance understanding of the innovative approaches taken in its realization. This analysis can serve as a foundation for dialogue on architectural practices in geologically significant contexts, underlining the importance of harmonizing design with its 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.
