Designed to reflect ancient Runestones, the facades integrate cultural and geological identity.
02
The atrium captures varying natural light, enhancing the interior atmosphere throughout the day.

05
A bridge over tectonic plates features a digital display tracking geological movements.

The Iceland Cave Tower features a modern design that aligns with the distinctive landscape of Iceland, particularly the Grjotagja caves. This structure serves multiple functions, including spaces for a café, lobby, and offices. It aims to enhance the experience for visitors and locals. The design draws inspiration from ancient Runestones, reflecting cultural heritage in contemporary architectural form.

Facade Design
The building displays two unique facades that highlight the contrasts in the region. The south facade is characterized by its light, reflective quality, reminiscent of iceflows and Iceland spar. This design creates a visual connection with the environment. In contrast, the north facade presents a volcanic look that relates to the area’s geological features. This dual approach not only contributes to the building's appearance but also symbolizes the relationship between day and night along the east-west axis.

Interior Experience
Central to the building is a full-height atrium that plays a critical role in its layout. This space allows for vertical movement and provides access to observation decks. The atrium captures natural light, transitioning from soft illumination to stronger beams throughout the day. This design choice fosters a connection between the occupants and the natural surroundings, enhancing the overall atmosphere.

Visitor Interaction
The journey within the building is designed for engagement and learning. A staircase leads to the Skywalk, with carefully positioned viewing stations that invite visitors to pause and reflect on the landscape. Opportunities to observe the Northern Lights deepen the connection between people and the environment, creating a memorable experience.

Ecological Integration
The surrounding landscape is carefully maintained, featuring paths made from basalt stone, wood, and steel. These walkways are designed to limit disruption to the ecosystem while allowing exploration of the natural features. Additionally, a bridge crosses the rift between tectonic plates and includes a display that tracks geological movement. This element further connects the structure to its environment, prompting interest in the Earth's natural processes.

The design culminates in an architecture that reflects cultural significance and ecological sensitivity. The atrium stands as a focal point, inviting natural light and linking the interior experience to the expansive landscape of Iceland.

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.
