Sintered stone and glass volumes coalesce in a mirage-inspired structure that extends toward the American Plate, creating an observation tower that enhances the visitor experience in the unique Icelandic landscape.
5 key facts about this project
01
Inspired by the Fata Morgana mirage phenomenon.
02
Comprises five geometric volumes to create visual lightness.
03
Designed to connect the Eurasian and American tectonic plates.
04
Features a geothermal heating system for energy efficiency.
05
Incorporates vertical wind turbines to harness local wind energy.

The MORGANA observation tower is located near the Grjótagjá Caves on the Eurasian Plate in Iceland. It serves as a visitor attraction that combines the area's natural beauty with stories from local mythology, particularly that of Morgan le Fay, also known as Fata Morgana. The design draws inspiration from the concept of a mirage, evident in the arrangement of geometric volumes that invites viewers to take in the surrounding landscape in a distinctive way.

Structural Design and Composition

The tower consists of five geometric volumes, three made from transparent glass and two crafted from sintered stone. This combination creates an effect of lightness and fluidity, which visually interacts with the environment. The volumes function independently yet connect through a central reinforced concrete elevator that maintains structural stability and accessibility throughout all levels.

Spatial Organization and Functionality

Inside the tower, spaces are organized to enhance the visitor experience. The ground floor includes an infopoint, restrooms, an office, and storage facilities to meet fundamental visitor needs. The first floor features a café and rooftop area, encouraging social interaction. Above, the second floor, known as "Iceland Soundland," immerses visitors in the unique sounds of the region. The third floor offers panoramic views of the surroundings, while the fourth floor embraces a theme called "Imagineland," exploring aspects of Icelandic culture.

Material Usage and Sustainability

Material selection plays an important role in the tower's overall character. Sintered stone is used for the solid elements, providing strength and stability within the rugged terrain. The glass sections allow natural light to flood the interiors and create a connection between inside and outside, enhancing the illusory aspect of the design. Sustainability is addressed through the use of vertical wind turbines in the parking area, which capture wind energy, and a geothermal heating system positioned below the building to support its energy needs.

The observation deck points outward, reaching toward the American Plate. It offers visitors a wide view of the unique Icelandic landscape, emphasizing the links between the myth, architectural form, and the natural world.

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.
