The Helix Tower, located near the caves of Grjótagjá, is a thoughtful example of how architecture can connect with its surroundings. The design reflects the area's unique geography, where two tectonic plates meet. The tower aims to explore themes of duality and harmony, creating experiences that resonate with visitors as they move through its spaces.

Design Concept

The tower features two spiraling paths that rise and twist around each other. These paths lead to a point at the top where they converge, symbolizing the blending of different identities. This design creates a practical way for people to move upward while allowing them to engage with their environment. The paths represent life’s complexities, encouraging conversations about identity and place.

Spatial Composition

At the center of the tower is a large skylight that serves an important role in illuminating the interior. This design feature connects the space below with the sky above, enhancing the natural light that enters. Along the spiraling surfaces are cuts that allow views outward. These openings create a changing perspective, helping people feel more connected to the outside world as they climb.

Ground Floor Experience

Visitors begin their journey by encountering a water well positioned in the center of the ground floor. This element offers both function and symbolism, inviting people to stop and reflect. The well contributes to a sense of peace, preparing guests for the ascent. It encourages individuals to consider their relationship with nature as they begin their journey upward.

Architectural Resolution

The Helix Tower stands as a reflection of its location, bringing together themes of human experience and environmental awareness. The careful arrangement of pathways, light, and open views creates a space for contemplation. As visitors reach the top, they find a vantage point that frames the landscape, completing the journey and connecting the structure to its scenic surroundings.

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.
