Subscribers only
Constructed primarily from recycled ocean plastics and enhanced with spray-foam insulation, the design offers a sustainable solution for efficient urban living.
5 key facts about this project
01
Constructed from nearly 90% recycled ocean plastics.
02
Features a modular design for flexible living arrangements.
03
Incorporates spray-foam insulation for enhanced energy efficiency.
04
Facilitates quick assembly through pre-assembled building parts.
05
Promotes community interaction with integrated outdoor spaces.

The RE:NEW House focuses on sustainability and the reuse of ocean plastics. Located in an environmentally aware setting, it serves as a residential solution for addressing the global challenge of plastic waste. The design integrates salvaged materials into a modular structure, representing a modern approach to housing that prioritizes efficiency and a strong connection to the natural environment.

Modularity and Customization

The design centers on modular construction, which allows for flexibility and customization. The layout can adapt to individual needs, promoting an efficient use of space, especially in urban areas. By incorporating outdoor spaces with indoor living areas, the project creates an inviting atmosphere that encourages community interaction.

Material Innovations

Materials are crucial to the performance and sustainability of the RE:NEW House. Pre-assembled plastic panels form the primary structure, designed with cavities filled with spray-foam insulation to enhance energy efficiency. The use of mold-formed wall panels introduces a lightweight and strong element, echoing methods used in boat construction. This ensures that the building remains resilient while also offering efficiency.

Thermal Performance and Climate Adaptation

Thermal performance is addressed through thoughtful insulation strategies incorporated throughout the design. The floor panels feature robust extruded beams filled with spray-foam insulation, improving energy efficiency and creating comfortable living spaces. The roofing materials, either corrugated metal or asphalt shingles, are chosen based on regional requirements, ensuring the home fits well within its local environment and climate.

Foundation and Drainage Systems

The foundation is constructed using poured concrete sonotubes, raising the building above ground. This design supports proper air circulation and drainage, which are essential for preventing moisture-related issues. By paying attention to these foundational details, the RE:NEW House demonstrates a commitment to building practices that prioritize sustainability and resilience in different environmental conditions.

This combination of design elements results in a functional housing solution that fosters community ties while maintaining a focus on sustainable practices. The balance between indoor and outdoor living enhances the overall experience for residents, making it a relevant design in today’s context.

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.
