The design located in Iceland presents a thoughtful exploration of how geothermal energy can be integrated into a sustainable framework. Set against a backdrop of geothermal activity, the building functions as a greenhouse, café, and exhibition space that highlights Icelandic culture. The overall concept emphasizes efficient resource use and aims to create educational experiences around sustainable practices.

Sustainability Focus

Emphasis is placed on sustainability through the implementation of a rainwater harvesting system. This system irrigates the greenhouse and showcases methods of functional agriculture. Combining rainwater collection with geothermal heating creates an energy-efficient environment. This strategy reflects a commitment to environmental responsibility and resource management.

Spatial Organization

The layout of the building carefully arranges functional spaces to encourage movement and interaction. A lobby welcomes visitors, leading into a dining area and various multi-purpose rooms. Each space is positioned to enhance the experience of engaging with cultural exhibits and agricultural displays. This thoughtful organization fosters a connection between users and their natural surroundings.

Vertical Greenhouse

A key feature of the design is the vertical greenhouse, which uses a three-dimensional approach to cultivation. This innovative method maximizes available space while educating visitors about modern agricultural techniques. Visitors can navigate a vertical traffic system that includes a rotating staircase, allowing them to view agricultural processes from different angles while appreciating the natural landscape outside.

Structural Elements

The selection of materials is crucial for both performance and aesthetics. Tempered insulating glass is used to maintain thermal comfort, while an aluminium frame provides structural strength. Structural adhesives and sealants support the durability needed to endure Iceland's specific climate challenges. These choices underline the project’s focus on robust environmental design.

Expansive glazing throughout the structure invites ample natural light and creates visual connections to the dramatic scenery. Views of glaciers and volcanic formations reinforce the relationship between the building and its environment. The design cultivates a sense of belonging, inviting visitors to appreciate both the architecture and the rich Icelandic landscape.

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.
