Set against the backdrop of Iceland's tectonic landscape, a timber structure, utilizing yakisugi for durability, elegantly connects two divergent continental plates while providing a sustainable space for visitor engagement and exploration.
5 key facts about this project
01
Two narrow bars symbolize the geological drift of tectonic plates.
02
Integrates a rainwater collection system for sustainability.
03
Uses yakisugi for enhanced durability and weather resistance.
04
Elevated pathing modules guide visitors through the landscape.
05
Provides panoramic views from the low-profile observation deck.

The design is set in the dramatic volcanic landscape of Iceland, specifically focusing on the Grjótagjá cave, which represents the division between two continental plates. It explores ideas of separation and connection through its form and interaction with the natural geological features of the area. Primarily intended for visitors, the structures enhance understanding of the surrounding environment while offering spaces for exploration and reflection.

Conceptual Framework

The layout is defined by two narrow bars that run parallel to the geological rift. One structure is tilted slightly to symbolize the drift of the tectonic plates. This design choice presents a clear visual representation of the ongoing geological changes. The architecture functions as an evolving inter-space, embodying the natural movement of the landscape.

Spatial Arrangement

A thoughtful arrangement improves visitor flow, allowing easy movement across the site. Elevated walkways lead people toward the cave entrances and buildings, fostering engagement with the surrounding geological features. By minimizing disruption to the natural setting, the layout enhances the overall visitor experience and encourages interaction with the landscape.

Sustainability Features

The western structure incorporates the technical components necessary for sustainable operation. The design makes use of geothermal energy systems, providing its own heating and power. In addition, a rainwater collection system and an on-site sewage treatment solution contribute to an eco-friendly approach. These features demonstrate a commitment to sustainability, ensuring that the structures operate in harmony with the environment.

Material Considerations

Materials play a significant role in the overall design. Timber flooring and timber battens constructed from spruce/yakisugi are used, along with black corrugated sheet and softwood cladding. The project also includes thermal glazing with wooden windows, which enhances the connection between indoor spaces and the natural surroundings.

An observation deck integrated into the western structure offers visitors expansive views of the unique landscapes. This design invites people to engage with the scenery and appreciate both the geological features and the architectural expression present at the site.

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.
