Incorporating locally sourced lava stone and recycled glass, the facility exemplifies sustainable architecture while serving as a community hub, greenhouse, and restaurant nestled in Iceland's unique volcanic landscape.
5 key facts about this project
01
Incorporates locally sourced lava stone as a primary structural material, enhancing its connection to the landscape.
02
Features a smart greenhouse that allows visitors to engage with local agricultural practices through real-time monitoring.
03
Utilizes ETFE film roofing to optimize natural light while minimizing thermal loss.
04
Integrates geothermal energy systems to achieve significant energy efficiency in heating and cooling.
05
The design echoes the landscape's natural topography with a bent A-frame structure, promoting visual harmony with the environment.

The project “Between the Lava” located at Vogajofos Farm Resort in Iceland exemplifies a thoughtful integration of architecture within a volcanic landscape. This facility is designed to serve multiple functions, including a restaurant, greenhouse, and multi-purpose space. The overarching aim is to create a harmonious relationship between the built environment and the natural surroundings, addressing both community needs and sustainability.

The facility is constructed using locally sourced materials that reflect the region's geological characteristics. Key materials include lava stone, recycled glass, laminated veneer lumber (LVL), mortar, and ETFE film. Each material is selected for its aesthetic and functional properties, emphasizing the project's sustainability goals while establishing a cohesive link to the landscape.

Architecturally, the building is organized into interconnected spaces that enhance user experience. The greenhouse not only serves as a production space but also as an educational venue, allowing visitors to engage with local agricultural practices. The restaurant is strategically positioned to offer panoramic views of its surroundings, providing an immersive dining experience that connects patrons to the natural beauty of Iceland. Additionally, the multi-functional hall is designed to accommodate various community activities, promoting engagement and wellness.

Unique Design Approaches

The design of “Between the Lava” stands out due to its direct response to the environmental context. The roof structure echoes the contours of the volcanic landscape, creating a seamless transition between natural and built forms. This approach addresses environmental factors such as wind and thermal regulation, ensuring energy efficiency within the building.

The incorporation of a geothermal energy system plays a crucial role in the project's sustainability. Harnessing the earth's natural heat reduces reliance on external energy sources and aligns with Iceland's commitment to renewable energy. Furthermore, the smart greenhouse incorporates technology that allows visitors to monitor growth conditions actively, enhancing the educational aspect of the design.

A significant aspect of the project is its focus on community interaction. The architectural layout encourages socialization while maintaining a connection to the landscape. This is achieved through both visual and physical connections, promoting a sense of place that is integral to the resort's identity.

Architectural Integration with Landscape

“Between the Lava” achieves a notable balance between human activity and environmental context. The use of lava stone for the structure grounds the building in its location, visually and texturally blending with the surroundings. Recycled glass elements provide transparency, allowing natural light to flow while reinforcing the connection to nature.

Overall, this project is an exemplar of sustainable architecture that prioritizes cultural and environmental sensitivity. The careful selection of materials and the innovative design approach make it a relevant case study for contemporary architectural practices. For a more in-depth understanding, consider reviewing the architectural plans, sections, and designs that further illustrate the thoughtful ideas behind this project.

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.
