"Haven on Earth" is an architectural design situated near the Serra de Estrela mountain range, specifically close to the Vale de Moses Yoga Retreat. The aim is to create a refuge that merges with the forest environment, highlighting the importance of sustainability and the comfort of its users. The overall design concept revolves around an elevated living space that reduces its impact on nature while fostering a strong connection between residents and the outdoors.

Elevation and Form

The Pod is built above ground, which minimizes disruption to the surrounding ecosystem. This elevation not only lessens the ecological footprint but also provides residents with distinct views of the landscape. Large windows are a key feature, offering expansive vistas and allowing natural light to flood the interior, enhancing the feeling of being surrounded by nature.

Interior Layout and Spatial Organization

Inside, the layout consists of two distinct areas: a bedroom equipped with a custom table-bed and a bathroom divided into three separate zones. Skylights add to the overall brightness of the space and create a sense of openness. This thoughtful organization promotes both comfort and practicality, ensuring that the living space feels cozy while maintaining a strong relationship with the environment.

Sustainable Features and Materiality

Timber is the primary material used in the Pod, reflecting a choice for renewable resources and enhancing the health benefits for its occupants. The natural qualities of timber support a smooth integration with the surroundings, which aligns with the project's focus on ecological responsibility. Additionally, features like a composting toilet and a gray water recycling system demonstrate an awareness of sustainable practices.

Architectural Performance

The design emphasizes effective solar panel orientation to maximize sunlight exposure and improve energy efficiency. Natural ventilation is facilitated through the use of sandwich panels, contributing to a comfortable indoor climate. The lightweight steel structure allows for quick assembly, minimizing the need for extensive site work, which aligns with the project’s respect for its natural setting.

The interior environment focuses on sensory experiences that enhance well-being. The design protects against external noise and temperature issues while welcoming natural sounds and light into the living space. This creates a balanced atmosphere where residents can feel connected to the natural world outside.

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.
