The project located at Hverfjall crater serves as an observatory designed for contemplation, creating a space where visitors can connect with the natural surroundings. Positioned on the edge of a volcanic crater that formed around 2,500 years ago, the design merges functionality with the dramatic features of the Dimmuborgir Lava Fields, enhancing the experience of those who come to observe the landscape.

Design Concept

At the heart of the design is a disk-shaped platform encircling an area dedicated to observation. This form closely follows the contours of the crater, establishing a dialogue between the architecture and the environment. The circular shape encourages visitors to immerse themselves in the geological history and beauty of the landscape, promoting a deeper understanding of the site.

Material Choices

The project utilizes materials that are in harmony with the local context. The platform is made from reinforced concrete, incorporating aggregates that mirror the tones of the land. This material choice fosters a visual connection between the structure and its surroundings. Additionally, a wooden step crafted from reused timber reflects traditional construction practices, emphasizing principles of sustainability and the importance of local resources.

Surface Details

Surface elements play a key role in offering insight into the landscape’s narrative. An engraving on the disk highlights the volcanic fault that runs through Iceland, linking the observatory to the geological history of the area. This design detail educates visitors about the environment, enhancing their experience and sense of place as they engage with the site.

Interaction with Landscape

A significant consideration in the design is the interaction between the platform and the ground below. The wooden step alters the typical expectations of form, creating an engaging interface with the landscape. This thoughtful approach encourages visitors to physically engage with their surroundings, inviting them to explore the site more closely.

Complementing the platform is a handrail made of painted fine-grain steel. The handrail consists of straight elements that resemble the movement of the northern lights, adding to the visual appeal. It serves a practical purpose while also enhancing the overall experience, highlighting the connection between the built environment and the natural beauty that surrounds it.

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.
