A dual-structured design incorporating reflective aluminum panels and local stone offers visitors a seamless experience of Iceland's unique landscape while serving as an informative center for geological exploration.
5 key facts about this project
01
Utilizes reflective aluminum panels to blend with the surrounding landscape.
02
Incorporates locally sourced stone to connect with Iceland's geology.
03
Features a dual-structured form to enhance visitor viewing experiences.
04
Designed for optimal natural light through strategically placed openings.
05
Integrates geothermal heating systems to promote energy efficiency.

The project titled "Split Wall" presents a contemporary architectural solution situated in a unique geological landscape characterized by the Grjótagjá Cave in Reykjahlíð, Iceland. This visitor center engages directly with the surrounding natural environment, emphasizing the relationship between human habitation and natural landform.

The design incorporates a split structural form that not only serves a functional purpose but also aligns with the regional topography. The main building elements allow a diverse range of activities, from contemplation to education about the geological and cultural significance of the area.

The structure's walls create designated viewpoints aimed at fostering interaction with the landscape, enhancing the visitors' experience. The entrance leads visitors through a corridor designed to optimize natural light, while the interior space can accommodate exhibitions that inform visitors about the region's geothermal features.

Materiality is a fundamental aspect of this project. The primary components include concrete for structural integrity, reflective aluminum panels that facilitate visual blending with the surroundings, locally sourced stone that pays homage to the native geology, and integrated vegetation that promotes ecological sustainability. This thoughtful selection of materials ensures that the building is not only functional but also sympathetic to its environment.

The "Split Wall" stands out due to its unique design approaches that embrace the philosophy of merging built form with the natural landscape. By utilizing a dual-wall concept, the project allows for varied spatial experiences, enhancing visitor engagement while maintaining a continuous dialogue with the outdoors. The design emphasizes transparency and accessibility, encouraging exploration of the cave and its geological context.

Incorporating mechanical, electrical, and plumbing systems geared towards energy efficiency demonstrates a commitment to sustainable practices in architecture. The project includes underfloor heating designed to harness geothermal energy, minimizing reliance on external energy sources.

The architectural strategy behind "Split Wall" not only fulfills functional requirements but also aspires to create an environment where visitors can appreciate the interaction between architecture and geology. The intentional use of light, strategic spatial design, and material choices contribute to an overall experience that highlights the region's unique characteristics.

For a deeper understanding of this project, consider exploring the architectural plans, architectural sections, and architectural designs presented. These elements will provide further insights into the innovative approaches and ideas that define the "Split Wall" architectural project.

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.
