"Dagr og Nótt" is situated in the distinct environment of Iceland, designed to represent the theme of duality through its exploration of opposites. The architecture illustrates the contrast between Ice and Fire, reflecting the island’s unique geological features. Two towers connect through a suspension bridge that adjusts itself, creating a dynamic relationship between the structures. Each tower provides a different experience for visitors, inviting engagement with the natural surroundings.

Design Concept

The concept behind "Dagr og Nótt" revolves around the interplay of light and dark. The dark tower welcomes visitors into a calm and quiet space, where soft lighting encourages reflection. In contrast, the light tower offers broad views that emphasize openness and connection to the landscape outside. This thoughtful transition between the two spaces symbolizes the movement between opposing states, reinforcing the theme of duality deeply rooted in the project.

Geological Context

Important to the design is its connection to Iceland’s geological characteristics, particularly the active tectonic landscape. The suspension bridge serves a significant role; it can self-adjust its length in response to movement in the ground below. This innovative functionality connects the structure to the natural environment, showing how the design integrates with the geological activity of the site, creating a dialogue between nature and construction.

Material Selection

Material choices throughout the project are carefully considered. The dark tower uses cast-in-place concrete, reflecting the natural basalt formations found throughout Iceland. This choice speaks to the area's geological history. The light tower, however, incorporates molten acrylic, designed to create interesting optical effects similar to the natural birefringence of calcite, a mineral well-known in the region. These materials enhance the visual experience while providing a tangible connection to the land.

Visitor Journey

Navigating through "Dagr og Nótt" offers an evolving visitor experience that highlights the contrasts between light and dark. Guests transition from the introspective atmosphere of the dark tower to the expansive views of the light tower, heightening their awareness of the surrounding landscape. Natural light is an important part of this experience, encouraging visitors to appreciate Iceland’s unique climatic variations.

The design culminates in an observation platform atop the light tower, where stunning views unfold. Here, visitors can take in the dramatic Icelandic landscape and connect with the natural beauty that surrounds them.

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.
