Constructed with a rammed-earth foundation and timber framing, the cabins provide a peaceful retreat in the heart of Vale de Moses, designed for meditation and connection with nature.
5 key facts about this project
01
Rammed-earth foundations enhance thermal performance and sustainability.
02
Timber framing allows for flexibility in adapting to the site’s steep topography.
03
A bioswale effectively manages greywater treatment and encourages ecological responsibility.
04
Panoramic views from the Treatment Room foster connection with the surrounding landscape.
05
Interior water wall feature creates soothing acoustics for a calming atmosphere.

The Meta-Cabins project is located in Vale de Moses, Oleiros, Portugal. It is designed to promote relaxation and contemplation within a natural setting. The design focuses on blending with the local environment while providing a unique experience for visitors. Situated on a steep hillside, the cabins make use of an existing stone terrace, adapting to the landscape’s contours and maintaining a close connection with nature.

Exterior Design
The cabins feature an exterior that utilizes locally available materials to reflect the traditional architecture of the region. The front facade is crafted to fit harmoniously within the rural environment, ensuring that the structures do not disrupt the landscape. A grid system of square panels gives the buildings a textured appearance, emphasizing calmness and clarity in their visual presentation.

Interior Experience
Inside, the design emphasizes a journey for visitors. Upon entering through a small foyer, they are drawn into a larger Treatment Room with expansive views of the valley. This gradual transition fosters a sense of tranquility, encouraging visitors to engage with both the interior space and the surrounding nature. The layout supports a contemplative atmosphere, promoting reflection and connection.

Water Integration
Water plays a key role in the design, serving practical and aesthetic needs. A rainwater collection system channels water from the roof into a water wall feature positioned in the foyer, which also functions as a handwashing station. This feature creates a soothing sound that enriches the visitor's experience. The project incorporates a bioswale for treating greywater, enabling responsible reuse of water while maintaining ecological awareness.

Structural Considerations
The cabins are supported by a dual structural system that includes lumber and timber framing on a stabilized rammed-earth foundation. A prefabricated steel exoskeleton is set on adjustable piers, allowing for flexibility as it adapts to the varied slopes of the terrain. This well-thought-out structural approach provides both stability and functionality, ensuring the cabins respond effectively to their environment.

The attention to detail in the exterior wall panels enhances visual interest. As sunlight moves throughout the day, it creates dynamic shadows, adding another layer of interaction between the cabins and the surrounding landscape.

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.
