Therapy Stone is an architectural design that blends contemporary living with the natural world. Located in Cambodia, the project aims to reconnect people with their environment. Its design concept emphasizes a return to simpler ways of living, focusing on sustainability and cultural significance while creating inviting spaces for users.

Concept and Spatial Organization

The design draws from the qualities of nature, such as agricultural lands, forests, and mountains. The spatial layout features an elevated structure built with a stacking method, which enhances air circulation. This approach encourages cross-ventilation, helping to keep the indoor spaces comfortable and reducing energy use.

Materiality and Construction Techniques

Rammed earth is the main material used in construction, serving a dual purpose. It showcases the importance of local building traditions and addresses the lifespan of materials. With its thermal mass, rammed earth helps manage indoor temperatures, decreasing the need for heating or cooling systems. Wood also plays a key role in the project, reflecting the deep-rooted history of building practices in Cambodia and adding warmth to the overall design.

Functionality and User Experience

The structure contains two separate boxes that organize public and private areas, promoting flexibility in how the spaces can be used. A large atrium in the center acts as a gathering place, allowing both community activities and private reflection. Natural light is a key feature; the atrium is designed with a polycarbonate panel to maximize daylight, creating a pleasant ambiance throughout the interior.

Environmental Integration

Sustainability is a central theme in the design, aiming to blend the building with its environment. Louvres are built into the structure to allow for natural airflow, responding to the local climate and enhancing user comfort. The arrangement of spaces and material choices reflect a thoughtful approach, ensuring the design respects and interacts with the surrounding landscape.

The connection between indoor and outdoor areas is expressed through large openings that provide clear views of the landscape. These features invite nature into the living spaces, further strengthening the bond between the architecture and its setting.

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.
