The Iceland Cave Tower is located in the remarkable geological landscape of Grjótagjá caves in Iceland. Functioning as both a watchtower and a lounge, it focuses on improving visitor interaction with the surrounding nature. The design integrates a bridge that crosses a geological crack, allowing easy access for guests to explore both sides of the site.

Design Concept

The architectural plan creates a strong connection between indoor areas and the outside landscape. The building is positioned thoughtfully, with lounges facing the stunning features of Hverfjall and Mývatn. Large glass windows in these lounges provide clear views of the environment. This openness helps visitors feel closer to the Icelandic landscape while enjoying the comfort of a sheltered area.

Functional Spaces

The lounge facing Hverfjall includes seating around an induction cooker. This setup encourages community and social interaction among visitors. Guests can enjoy drinks and snacks while watching the landscape shift throughout the day. A café is also present, offering a casual space for relaxation, contributing to the overall inviting atmosphere of the tower.

Visitor Experience

Height plays an important role in the design, with multiple levels offering different viewpoints. Visitors can ascend the tower to take in the area from above. The atrium provides protection from harsh winds, ensuring comfort while enjoying the sights. Additionally, a parking area on the northeast side allows for straightforward access, enhancing the arrival experience for visitors who come by car.

Design details throughout the building reflect a careful balance between nature and architecture. Spaces are arranged thoughtfully to enhance visitor enjoyment. The combination of functional elements and natural beauty enriches the connection between people and the unique 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.
