Protruding cones capture natural light while a corrugated metal roof provides durability in a building designed for observation and interaction within the unique landscape of Grjótagjá caves.
5 key facts about this project
01
Protruding cones enhance natural light entry and spatial dynamics.
02
A lightweight design allows for potential relocation as environmental conditions change.
03
Black steel structure develops a patina over time, adding visual character.
04
Timber deck extends to the fissure, inviting direct interaction with the landscape.
05
The independent public cave retains its natural conditions, fostering an authentic experience.

The design emerges from the landscape of the Grjótagjá caves, which are known for their hot springs and striking geological features. The setting informs a concept that focuses on adaptability and the connection between structures and their environment. A Tower serves as both an observation point and a multifunctional space, illustrating the relationship between human presence and the ever-changing natural world.

Structure and Form

At the center of the design is the Tower, a tent-like structure that combines elements of an observation tower with an elongated base. This form accommodates various functions while aligning with the North-South axis. Large windows frame views of Krafla to the North and Hverfjall to the South, allowing natural light to enter and connecting visitors with the landscape outside.

Visitor Engagement

Visitors begin their experience along modular walking paths that lead from the parking area to the entrance of the Tower. These pathways invite exploration and interaction with the surrounding nature. A timber deck extends toward the fissure, encouraging visitors to take in the geological features. Protruding cones incorporated into the design capture natural light, enhancing the spatial quality and creating an atmosphere of calm.

Material Considerations

The design uses lightweight elements, with a corrugated metal roof supported by a black steel structure. This choice of materials reflects the intention for adaptability, making it possible for the building to be relocated if necessary. Over time, the black steel will oxidize, adding a sense of texture that blends with the natural environment.

Spatial Dynamics

The Tower’s design reflects a cave-like experience through its layers, which creates unique and inviting spaces for visitors. The public cave remains separate from the main structure, ensuring that its natural conditions are preserved. This separation allows for a gentle interaction between the built environment and the geological landscape.

The design ultimately emphasizes a balance between architecture and nature. Light-filled spaces provide a connection to the surrounding area while recognizing the importance of preserving its fragile beauty.

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.
