05
Wire mesh railings enhance safety while allowing natural light to benefit solar functions.

The observation tower is positioned to represent the relationship between the tectonic plates of Europe and America. Set within the landscape surrounding Hverfjall mountain and the Kvennagjà and Karlagjà caves, the design merges functionality with sensitivity to the environment. The concept features a dual structure made up of a transparent frame and a solid core, highlighting the contrasts inherent in the geological context.

Design Structure

The design of the tower facilitates an engaging experience for visitors. The gap between the two main components serves as an entrance, welcoming users into an immersive space. The solid core leads to a viewing platform offering broad views of the landscape, including the fissure and nearby natural formations. Positioned on the south side, these platforms maximize daylight and frame the scenic surroundings.

Visitor Center

Next to the tower, the visitor center is built underground, making it less noticeable while still accessible. This design choice protects the overall visual appeal of the site, allowing the tower to stand out prominently. The center features essential facilities such as a bar, office areas, restrooms, and washing facilities for visitors who have spent time in the nearby caves. The path from the visitor center to the tower is designed to reduce elevation changes, creating a straightforward journey between the indoor and outdoor areas.

Materiality and Sustainability

The tower’s structure relies mainly on steel, with the solid core covered in metal sheets that contrast with the warm wood found inside. Concrete is used in the construction of the visitor center, providing a sturdy base while blending with the surrounding terrain. The walking path leading to the tower is minimalist, also made of steel, and includes solar panels that generate energy to support its operations. This feature demonstrates a focus on sustainability and reducing environmental impact.

Railings along the paths are made of wire mesh, allowing sunlight to reach the solar panels while ensuring visitor safety. This balance of aesthetics and practicality contributes to the overall design, reinforcing the connection between the built environment and its geological foundation. Special details enhance the architectural concept, emphasizing simplicity while inviting exploration and appreciation of the natural landscape.

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.
