The Gròtagjá caves in northern Iceland provide a dramatic setting for a visitor center that connects the built environment with unique geological features. Designed to serve as both a functional facility and an experience hub, this space highlights the region's geothermal springs and striking lava rock formations. The overall concept focuses on fostering a meaningful interaction between visitors and the surrounding landscape, reflecting Iceland's deep cultural ties to nature.

Spatial Organization

The visitor center's layout is carefully planned to enhance the experience for those who enter. Key areas include a reception area, changing rooms, staff quarters, and a café, providing essential services while allowing for easy movement throughout the building. As visitors explore, they are guided naturally through thoughtfully arranged spaces. An elevated viewing platform grants expansive vistas, connecting guests with the overall narrative of the Icelandic landscape.

Architectural Form

The building features an angular silhouette that mirrors the rugged geology of the area. This distinct shape is both a visual landmark and a source of shelter and comfort within the landscape. Skylights are strategically placed to bring in natural light, creating a welcoming atmosphere inside. The geometry of the structure serves to reinforce its connection to the environment while offering an engaging visual experience.

Material Selection

The choice of materials reflects a commitment to sustainability and harmony with the landscape. Features such as double-glazed skylights provide ample light while maintaining energy efficiency. Stone slate roofing blends the structure into its surroundings, creating a cohesive appearance. The interior is finished with cross-laminated timber, which adds warmth and comfort. Steel frames ensure durability, supporting the building's structure against the elements.

Design details include a private pathway leading to the changing rooms, designed to minimize environmental impact while providing privacy for visitors preparing to enjoy the geothermal springs. The careful play of light and shadow throughout the space enhances the connection between the architecture and the natural surroundings, creating a sensory experience that invites reflection and exploration.

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.
