5 key facts about this project
01
Moss-covered facades encourage natural growth, enhancing ecological integration.
02
Curved concrete shells provide structural support while mimicking natural forms.
03
Skylights designed as analogs to cave fissures offer dynamic lighting throughout the day.
04
The layout promotes a seamless flow of visitors through exhibition and exploration areas.
05
The design reflects local architectural traditions while employing sustainable practices.

The design located near Grjotagja cave in Iceland enhances the visitor experience while honoring the natural landscape and local culture. The project aims to connect people with the geological significance of the caves. By placing the car park farther from the entrance, the design focuses on the caves themselves. This decision encourages visitors to immerse themselves in the unique environment that defines the site.

Conceptual Framework

The project draws inspiration from vernacular architecture, particularly turf houses. This influence is visible in the integrated roof that blends visually with the landscape. The design enhances the site's character and functionality, creating a harmonious relationship with the terrain. Each element is purposefully chosen to contribute to the overall experience.

Architectural Features

Skylights are a key feature of the design, mimicking natural cave formations. They allow light to enter interiors, creating a bright and inviting atmosphere. As natural light changes throughout the day, it transforms the spaces within the building. This dynamic interaction fosters a strong connection between the interior and the surrounding landscape, drawing visitors in.

Visitor Experience

The visitor center acts as a gateway to the Icelandic landscape, encouraging exploration and learning. A well-thought-out flow of activities, including exhibitions and management areas, enhances visitor engagement. One notable feature is the bridge-like extension of the skylight, which provides elevated views of the remarkable environment. This connection encourages visitors to engage meaningfully with the natural surroundings.

Materiality and Sustainability

Material choices reflect an emphasis on ecological integrity. Loose brick joints filled with seeds encourage moss growth, creating a living facade that remains connected to nature. Lightweight imitation stone bricks integrate with the landform, while a curved concrete shell offers structural support. A light steel truss system allows for spacious interiors that prioritize sustainability.

The interior spaces are finished with gypsum board, ensuring simplicity and functionality. Each design choice respects the site's geological and cultural significance. The focus is on creating a welcoming environment that invites visitors to explore and appreciate Grjotagja cave and its 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.
