Incorporating wooden walls and an underground rainwater collection system, the design prioritizes sustainability while creating a functional living space for modern residential needs.
5 key facts about this project
01
Incorporates an underground rainwater collection system for efficient water management.
02
Utilizes wooden wall layers to enhance thermal performance and aesthetics.
03
Features solar panels designed for optimal energy capture on the roof.
04
Emphasizes vertical levels to define distinct functional areas within the home.
05
Prioritizes sustainable living with a focus on eco-friendly materials and energy sources.

The design combines sustainability with practical living, situated within a contemporary residential environment. The focus is on maximizing functionality through the creative use of vertical levels. This approach not only enhances the layout but also supports environmental initiatives, including rainwater collection and solar energy usage, reflecting a commitment to ecological awareness.

Vertical Levels
The project makes effective use of verticality, creating a sense of movement and flow in the interior space. By introducing varying heights, different functional areas are established. This not only improves usability but also contributes to an open and engaging atmosphere, ensuring that every space serves a purpose in the day-to-day life of its inhabitants.

Rainwater Management
An important aspect of the design is the rainwater management system. The roof's structure is carefully crafted to collect rainwater and direct it into an underground tank. This method helps reduce reliance on external water sources, highlighting the project's dedication to conservation. By integrating this feature, the design promotes responsible water usage, suitable for a modern lifestyle.

Solar Energy Integration
Solar panels are incorporated to enhance energy efficiency throughout the home. The roof is tailored to accommodate these panels effectively, allowing the collection of renewable energy. This aspect of the design not only addresses the energy needs of the family but also supports larger sustainability goals within the community.

Materials and Aesthetic Considerations
Wooden wall layers are utilized to add warmth and improve thermal regulation. This choice of material aligns with the project’s sustainability objectives by fostering a natural environment inside the home while complementing the architectural style. The wood enhances the connection with nature and creates a calming atmosphere.

The design culminates in a roof that is both functional and visually appealing, capturing rainwater while maximizing sunlight for energy use.

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.
