5 key facts about this project
01
Sculpted concrete bridges blend seamlessly with the landscape.
02
Multiple levels provide diverse visitor experiences and functions.
03

04

05
Natural soil integrates into the structure, reinforcing landscape connection.

The Grjótagjá's Caves Tower is situated in a rocky volcanic landscape. Designed to function as a guiding and interactive space, it provides a warm refuge in an otherwise cold and windy area. The structure's unique form enhances the exploration experience for visitors heading to the nearby caves.

Architectural Concept

The design focuses on creating a connection between the building and its natural surroundings. It demonstrates how constructed elements can work in harmony with the landscape. The tower’s shape invites visitors to engage with both its inside and outside, reflecting the rugged features of the geological context. It serves as a landmark that integrates with the site’s characteristics.

Pathways and Accessibility

An important feature of the design is the low-impact walking paths that enhance visitor access. These paths are made of lighter color gravel that contrasts with the natural soil, making them easy to follow. This careful approach to path design prioritizes accessibility while respecting the environment, improving the overall visitor experience.

Structural Elements

The project includes bridges made from sculpted concrete rocks that rise from the ground. These structures add visual interest and provide stability. They help to connect the tower with the surrounding landscape while facilitating movement throughout the site. The bridges emphasize the relationship between architecture and nature.

Interior Levels

Inside, the Grjótagjá's Caves Tower has multiple levels, including a Top Level, Sight Level, Cafeteria Level, Services Level, and Entrance Level. Each level is designed to support different activities and allow for smooth movement between spaces. This organization fosters a sense of connection and engagement as visitors explore the tower.

Large windows frame the most impressive views of the landscape, linking the interior with the outside. They allow natural light to fill the spaces and create a dynamic atmosphere that changes throughout the day.

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.
