The Grjótagjá Horizontal Viewing Tower is set in a unique geological area of Iceland, located between the caves of Karlagjá and Kvennagjá. It serves as a platform for visitors to observe the striking landscape, which features dramatic geological formations. The design concept emphasizes accessibility, enabling people of all abilities to engage with the natural surroundings. Its architecture harmonizes with the environment, encouraging a deeper connection between visitors and the landscape.

Design and Accessibility

The design includes a gentle slope that leads visitors through the site. This pathway is primarily free of stairs, promoting ease of access for everyone. The incline is set at 1:12.5 (8%), with resting landings every 10 meters to break the journey into manageable sections. Three observation piers extend from the tower, designed to enhance the experience of viewing the landscape. These piers invite visitors to pause and appreciate the beauty of their natural surroundings.

Environmental Integration

Careful planning minimizes the disturbance to the landscape. The structure connects to the ground only at essential points, preserving the natural contours of the area. Visitors can move safely across fissures, allowing them to explore without impacting the environment. This thoughtful approach to design reflects a commitment to sustainability, ensuring that the tower fits comfortably within its setting.

Sustainability Features

Sustainability is a core aspect of the tower's design. Geothermal energy is used for heating, and rainwater is collected from the sloped roof, which is designed to manage snow buildup. These systems showcase effective environmental management, highlighting a responsible approach to building in a sensitive landscape. The focus on sustainability ensures that the structure serves its purpose while remaining considerate of its ecological context.

Materiality and Construction

Locally sourced wood and steel are the primary materials used in the construction. Round timber beams provide structural support, while square-cut wood poles and steel elements form the framework of the tower. These materials were selected not only for their sturdiness but also for their compatibility with the local environment. This choice enhances the connection between the structure and its natural surroundings.

The design includes open areas that allow natural light to enter, creating a welcoming environment for visitors as they engage with the landscape. The viewing platforms provide opportunities for reflection and appreciation of the geological beauty that envelops them.

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.
