5 key facts about this project

The design located in Grjótagjá, Iceland, responds directly to the remarkable geological features of its setting. It provides functional spaces while inviting visitors to explore and connect with the landscape. The concept focuses on the interplay between solid construction and the ephemeral qualities found in the natural environment, allowing people to experience the surroundings in a meaningful way.

Form and Structure

A prominent tower is the central feature, rising from the terrain to create an ascent into the expansive Icelandic landscape. The design reflects the area's topography, guiding visitors as they move upward. The interior spaces offer a variety of atmospheres, with dark areas transitioning to light, creating a flowing experience that highlights the relationship between the building and its environment.

Material Expression

Materials are chosen for their ability to complement the surroundings. The polished exterior helps the structure integrate into the landscape while also standing out against the rugged terrain. However, where the building appears to fracture, coarser textures are revealed. This contrast tells a story about geological changes, linking the architecture to the natural processes occurring beneath the surface.

Spatial Experience

The interiors are designed to foster visitor interaction, addressing practical needs alongside the exploration of space. Facilities like public toilets and an office are carefully incorporated to support the overall experience without disruption. Internal spaces are organized to maintain a connection to the outside world, inviting light to flow through and creating a dynamic atmosphere as visitors progress through the tower.

As people ascend the tower, the layout encourages discovery and reflection. Each level offers new views of the surrounding landscape, enhancing the journey. Narrow openings lead to expansive vistas, providing a final, powerful moment of connection with nature. The design invites engagement, ensuring that the experience remains grounded in the landscape while also serving practical needs.

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.
