The Rumduol Cabin is located in Cambodia and exemplifies a thoughtful blend of traditional design with modern sustainable practices. Inspired by the national flower, the Rumduol, the cabin forms a connection to the local environment. It serves an eco-tourism function, offering a welcoming space for visitors while emphasizing the importance of conservation and ecological responsibility. The design reflects challenges such as deforestation and aims to create a positive impact within its surroundings.

Symbolism and Form

The design of the Rumduol Cabin draws heavily from the form and symbolism of the Rumduol flower. The structure has a roof that resembles the flower's petals, creating a visual link to nature. This design is not just for aesthetics; it plays a crucial role in the cabin's functionality, particularly in relation to water collection and drainage.

Water Management and Climate Adaptation

The large roof of the cabin is designed to capture rainwater effectively. During monsoon seasons, this water is collected and stored in barrels located at ground level. This system ensures that water is available for use during drier months, highlighting an innovative approach to resource management. In addition, the cabin promotes natural ventilation, which helps maintain a comfortable indoor environment, despite the hot and humid conditions typical of the region.

Use of Local Materials

Local materials are integral to the construction of the cabin, reinforcing its connection to the area's culture and heritage. The walls are primarily made from rice palm leaves, while bamboo is utilized for both structural and decorative purposes. These materials are not only environmentally friendly but also uphold traditional building methods, providing a sense of identity and continuity within the community.

Sustainability and Ecological Impact

Beyond its construction materials, the cabin is designed with a strong focus on sustainability. It incorporates solar power to meet energy needs, achieving a net-zero energy balance. Waste generated on-site is composted, enriching the surrounding soil and supporting agricultural practices. This approach positions the cabin not only as a living space but also as an active contributor to local ecological restoration efforts.

The roof's design stands out not only for its functionality in water collection but also for its ability to provide shade, creating comfortable outdoor areas for relaxation and interaction with nature.

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.
