The Green Diamond project emerges within the volcanic landscape of southern Iceland, designed to merge public functions with a high-tech greenhouse. It stands as a multifunctional facility that encourages community interaction and supports agricultural activities. The overall design focuses on being elevated above the ground, allowing for unobstructed views of Hverfjall Volcano and Lake Mývatn while maintaining a connection to the surrounding natural environment.

Site Integration

The shape of the Green Diamond is distinctive, featuring a diamond-like superstructure that lightly touches the slope. This careful positioning creates a sense of accessibility while maximizing the picturesque vistas it overlooks. From the high point of the entrance, visitors are welcomed into the building. The outdoor public routes guide them toward spacious viewing decks, enhancing their engagement with the landscape.

Functional Arrangement

Inside, the building clearly separates agricultural space from public areas. The high-tech greenhouse is strategically placed to capture the best views, while community spaces like the Green Diamond Shop and Restaurant are seamlessly integrated. This layout encourages movement throughout the facility, allowing visitors to experience local produce and partake in community events held in the versatile Green Diamond Hall.

Sustainability Features

Sustainability forms a key aspect of the design. The structure is constructed using a grid of galvanized steel, allowing for modular construction and easy reassembly. This choice supports the principles of cradle-to-cradle design, which prioritize the reuse of materials. Untreated timber is used for interior finishes, contributing to minimizing environmental impact and promoting reusability.

Energy Efficiency

The building incorporates several energy-efficient systems, including geothermal heat pumps and solar panels, alongside water-based heat collectors from the greenhouse. This combination ensures self-sufficiency while reducing dependence on outside power sources. The design emphasizes a commitment to sustainability in both energy usage and materials.

The viewing deck provides a direct connection to the vast landscapes. It encourages visitors to appreciate the surrounding beauty, blurring the lines between indoor and outdoor spaces. This detail highlights how the design not only serves a functional purpose but also invites users to engage with the natural environment as an essential part of the experience.

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.
