The HRING Community Center project is an architectural endeavor located in Iceland, designed to serve as a multifunctional space that fosters community engagement and environmental stewardship. The center's design embraces a circular form that optimally integrates with the surrounding landscape while encouraging social interaction among visitors. This structure is not only a hub for community activities but also reflects the principles of sustainability and ecological responsibility inherent in contemporary architectural practices.

Circular Form and Spatial Organization

The circular configuration of the HRING Community Center facilitates an efficient layout that revolves around a central atrium. This atrium serves as the heart of the building, providing natural light and visual connection between the different functional areas. On the first floor, essential facilities such as waste management zones and parking for service vehicles are strategically positioned to promote operational flow. The incorporation of a greenhouse within this level emphasizes an educational component, allowing visitors to engage with vertical gardens. The second floor features community-oriented spaces designed for children, meeting rooms, and product sales areas. This layout maximizes accessibility and encourages the use of the center for various purposes.

Sustainable Materiality and Construction Techniques

The HRING project distinguishes itself through its commitment to sustainable construction practices and material choices. Several key materials have been selected based on their environmental qualities. Reinforced concrete made from a notable percentage of recycled construction waste reduces the carbon footprint associated with traditional concrete usage. The exterior facade utilizes Icelandic granitic gneiss, which not only enhances the aesthetic but also provides durability suitable for local weather conditions. Inside, composite panels made from recycled plastics and concrete contribute to the center's overall sustainability while promoting an innovative approach to interior finishes. Terrazzo flooring made from locally sourced aggregates further exemplifies the project’s focus on regional materials.

Innovative Landscape Integration

Part of the HRING Community Center's architectural approach is its thoughtful integration within the natural landscape of Iceland. The circular design mirrors natural forms found in the surrounding environment, creating visual harmony. This architectural strategy is complemented by careful landscaping that extends the building’s footprint outdoors, allowing the structure to engage with the natural world. The atrium not only functions as a transitional space but also incorporates a vertical garden, fostering a connection between indoor activities and the biodiversity outside.

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.
