The Grjótagjá Cave Observation Tower and Visitor Center is located in the heart of Iceland, where the earth's tectonic plates create a dramatic landscape. This structure serves as both a visitor center and an observation point, inviting people to explore the unique geological features of the area. The design reflects the region’s natural processes, featuring two large prismatic forms that symbolize the movement of tectonic plates, separated by a calm body of water that mirrors the nearby Grjótagjá cave.

Design Concept

The building has a sizable footprint and rises to nine stories, making it a prominent feature in the scenery. Visitors arrive via a path lined with rough lava rock, enhancing their connection to the surrounding environment. The façade draws inspiration from the shapes of volcanoes, showcasing layers of solidified lava and volcanic ash. This visual representation emphasizes the geological history of the area and engages viewers with the site’s unique characteristics.

Interior Layout

Inside, the layout encourages exploration and interaction, starting at a warm vestibule that leads into the visitor center. A thoughtfully designed circulation system guides visitors through the building. "Stair - Orange" leads upwards to an observation platform with sweeping views of Mývatn lake and Hverfjall volcano caldera. In contrast, "Stair - Green" invites visitors to descend while taking in views of Hverfjall. An elevator makes the building accessible for everyone.

Environmental Integration

Natural light fills the building, thanks to a double-glazed curtain wall that surrounds a Cross Laminated Timber frame. This combination creates a bright and welcoming atmosphere. The structure utilizes a geothermal heating system that includes underfloor hot water, reflecting a commitment to energy efficiency. Sustainability practices are evident as well, with kitchen organic waste composted, human waste processed for ecological benefit, and systems in place to collect rainwater for drinking.

Exterior Details

The polished lava stone reflection pool in front of the building adds to its visual interest, reflecting the structure as it captures daylight. This water feature emphasizes the theme of natural processes, serving both aesthetic and practical purposes. The contrast between the building's forms and the rugged landscape helps create an experience that encourages visitors to engage with the natural world, making it a significant destination in the region.

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.
