"The Upside Down" is an architectural design that creates a relationship between structure and landscape. Set in a location marked by significant geological features, it features a cave tower that serves both as a viewpoint and a destination for visitors. The design aims to enhance the experience of the natural environment, encouraging exploration and interaction with the surrounding landforms.

CIRCULATION AND ACCESS

The design incorporates two main ways for visitors to move through the space. One option is a continuous ramp leading to an observation dock, making it accessible for everyone. The second choice involves a climbing path built into the cave tower, adding an adventurous element to the experience. This climbing area allows visitors to engage more deeply with the cave-like structure and connect with the geology of the site.

SPATIAL DYNAMICS

The building is divided into two blocks, representing the geological separation found in the area. This division creates interesting spatial relationships that offer different experiences at each level. Elevated sections of the tower are designed to maintain clear views of the surrounding landscape. Sightlines to landmarks such as the Hervfjall volcano and Maylatain lake are preserved, enhancing visitors' appreciation of the region's natural beauty.

STRUCTURAL INNOVATION

The choice of a customized timber modular grid for the structure supports both sustainability and design flexibility. This system allows for the use of smaller, lighter components, making construction more efficient. Choosing wood aligns with modern efforts to use environmentally friendly materials, strengthening the project's connection to its surroundings.

The design also incorporates environmental strategies that address the site's geological context. High annual humidity levels create opportunities for using atmospheric water generation and exploring geothermal energy. These elements reinforce the building's fit within the local ecosystem.

At the heart of "The Upside Down" is an invitation for visitors to explore a compelling narrative with the earth. As they ascend through the cave tower, they are surrounded by deep views of the dramatic Icelandic landscape, resulting in a memorable experience of place and nature.

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.
