Crafted from ETFE and steel, the spiral structure rises from the Icelandic landscape, providing a unique geological observation point that seamlessly integrates cultural symbolism with sustainable design practices.
5 key facts about this project
01
Constructed with lightweight ETFE, enhancing thermal efficiency and natural light.
02
The design draws inspiration from Jörmungandr, the Norse serpent, symbolizing geological connectivity.
03
Incorporates photovoltaic panels for self-sustained energy generation.
04
Features a central circulation core that reinforces structural stability against wind.
05
Offers multiple observation platforms for panoramic views of the surrounding rift landscape.

The Midgard Turn Tower is an architectural project situated in Grjótagjá, Iceland. This structure serves as both an observation point and a cultural symbol, reflecting the geological phenomena and Norse mythology intrinsic to the region. The design is rooted in the relationship between the North American and Eurasian tectonic plates, illustrating the dynamic interplay of nature that defines Iceland’s landscape.

The Midgard Turn Tower integrates a spiral form, which is inspired by Jörmungandr, the mythological world serpent. This distinctive shape not only contributes to the tower’s aesthetic appeal but also enhances its functionality, allowing for a variety of observation platforms that provide panoramic views of the surrounding terrain. The design emphasizes a strong connection to the geological forces at play, creating an immersive experience for visitors.

The architectural approach taken in this project emphasizes sustainability and energy efficiency. Several innovative features are incorporated, starting with the selection of materials. ETFE (Ethylene Tetrafluoroethylene) is used for its transparency and insulation properties, allowing natural light to penetrate while maintaining thermal comfort. Reinforced steel framework ensures structural integrity, which is critical given the environmental conditions in the area.

Photovoltaic panels are integrated into the design, effectively harnessing solar energy to support the tower’s energy needs. This self-sufficiency is enhanced by the use of thermal-glazed windows which provide passive heating, optimizing energy consumption. The careful selection of materials contributes to a reduced environmental impact, aligning with sustainable architecture practices.

The tower also features a circulation core that facilitates movement throughout the structure, enhancing user experience. This core not only serves a practical purpose but also reinforces the architectural integrity against harsh wind conditions. The interconnection of these design elements results in a cohesive structure that prioritizes both form and function.

The Midgard Turn Tower differentiates itself from other architectural projects through its integration of cultural narratives with ecological considerations. It exemplifies a thoughtful approach to site specificity, where the design directly reflects the geological and historical context of the area. Visitors can engage with the landscape in a meaningful way, promoting a deeper understanding of the natural forces that shape Iceland.

For further exploration of this project, interested readers are encouraged to review the architectural plans, architectural sections, and architectural designs available for a comprehensive understanding of the ideas and objectives behind the Midgard Turn Tower.

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.
