### Overview
The EcoModular project is situated in Ukraine and addresses the urgent need for housing reconstruction following conflict-related destruction. This initiative integrates modular building techniques with eco-friendly materials to create resilient urban environments. By prioritizing sustainability, the design focuses on efficient construction and the development of vibrant communities within the existing urban fabric.

### Spatial Strategy and Community Integration
The EcoModular design employs a modular kit-of-parts approach, offering flexibility in the construction of multifamily housing units. This strategy enhances adaptability to varying housing needs while maintaining eco-friendly standards. The design incorporates essential elements like emergency shelters, green spaces, and communal areas, promoting the principles of a "15-minute city," which emphasizes accessibility to vital services. The arrangement of public spaces encourages social interaction and pedestrian connectivity, aiming to foster a sense of community among residents.

### Materials and Structural Integrity
The selection of materials in the EcoModular project reflects a thoughtful commitment to ecological sustainability and structural robustness. Key materials include wheat-based biobased products, chopped straw panels that provide substantial insulation, and locally sourced cladding materials. Concrete is utilized for foundational elements, ensuring durability, while wood and straw components contribute to both aesthetic appeal and environmental efficiency. This combination illustrates an innovative approach that balances modern construction techniques with traditional material use, enhancing both sustainability and functionality within the design.

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.
