The Black Lava Fields Visitors Center is located in the dramatic volcanic terrain of Iceland. It is designed to educate visitors about the local environment and the importance of reforestation. The center serves multiple purposes, featuring a greenhouse where seedlings are nurtured, a café, and spaces for information and engagement. The design aims to connect the building with its natural setting, creating a supportive environment for both people and nature.

Design Concept

The design is inspired by the natural contours of the nearby hiking trails. This creates a connection between the building and the landscape. Elevated pathways allow visitors to take in views of notable features like Myvatn and Hverfjall, enhancing their appreciation of the surroundings. The design encourages exploration and interaction with the landscape.

Functional Organization

Central to the visitors center is a greenhouse dedicated to growing tree seedlings. This aspect supports the center’s focus on reforestation. The greenhouse is divided into sections that correspond with the age of the trees, offering a hands-on experience for visitors. By positioning the youngest seedlings near the entrance, the design invites direct participation and fosters a sense of responsibility for the environment.

Infrastructure and Materiality

Around the center, the infrastructure is designed to minimize environmental impact. A two-level car park accommodates visitors while preserving the landscape. The lower level is intended for bus parking and is integrated into the terrain. The façade incorporates volcanic ash concrete, blending with the local geology and reinforcing the relationship with the natural surroundings.

Architectural Details

A continuous wooden wall guides visitors throughout the building. This design element serves both practical and aesthetic purposes, encouraging movement within the space. It also highlights a deeper connection to nature, reflecting the commitment to ecological awareness. The details in the building reveal a careful thought process focused on promoting environmental responsibility.

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.
