"ONE" is an innovative response to the increasing need for sustainable housing in urban areas. Located in a modern setting, the design seeks to balance functionality with environmental considerations. It draws on the concept of unity, reflecting cultural influences, particularly from Chinese perspectives on community and space, to create an engaging living environment.

Design Characteristics

The project features an elevated platform that reduces the impact on the site during construction. This approach allows the building to connect more closely with its natural surroundings. The choice of elevation helps maintain the ecological integrity of the area while offering residents a unique perspective of the environment.

Sustainability Features

One of the key elements of the design is the tilted roof, which is home to Crassulaceae plants that aid in rainwater collection. This feature enhances the building’s environmental performance and contributes to the local ecosystem. Additionally, solar panels are integrated into the roof, providing renewable energy and supporting a sustainable lifestyle.

Spatial Organization

Inside, the layout promotes interaction among residents. The design connects the living room, kitchen, and terrace, encouraging communal activities. In contrast, bedrooms and bathrooms are positioned to ensure privacy. This thoughtful arrangement allows for both social engagement and personal space, creating a balanced living experience.

Details of Integration

With a total area of 68 square meters, the design makes efficient use of space, accommodating essential functions while maintaining comfort. The use of recyclable materials throughout the project reflects a commitment to sustainability. These aspects together result in a design that prioritizes practical living and environmental responsibility, highlighted by its distinctive features that facilitate both functionality and beauty.

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.
