The retreat center in a forest valley in Portugal focuses on spiritual retreats, creating spaces that encourage personal reflection and growth. It is designed to connect people with nature while offering a supportive environment for therapeutic practices. Inspired by traditional clay cabins and local building styles, the design incorporates elements from human energy field systems, enhancing the holistic experience for users.

Circular Forms and Functionality

The center consists of several circular structures that accommodate two people each. These spaces are carefully arranged on a gentle slope, taking advantage of the natural landscape. Each structure serves two distinct purposes: the lower level is designed for therapeutic treatments, while the top level offers a private area for personal retreat. This setup allows participants to engage in both group activities and solitary reflection.

Spatial Dynamics and Light

A key feature of the design is its use of circular forms, which help to create a calm atmosphere. The dome-like shapes minimize stress by promoting a sense of balance and stability. Natural light plays an important role as well; zenithal openings in the roofs allow sunlight to enter and illuminate the spaces. This connection to the outdoors enhances feelings of peace and isolation, providing a comforting environment for contemplation.

Sustainability Features

The retreat center embraces sustainability through its design choices. Adaptable photovoltaic panels are installed to capture sunlight efficiently, adjusting their angle to maximize energy production. Additionally, a rainwater harvesting system channels water to storage areas beneath the building, illustrating responsible resource management. The use of laminated wood slats for the structure provides strength while maintaining a simple aesthetic.

Distinctive Architectural Elements

Every detail of the design is meant to resonate with the surrounding landscape. The circular shapes and natural lighting work together to create environments that inspire personal exploration. Each structure becomes not only a functional space but also a place for deep reflection, inviting individuals to engage meaningfully with both themselves and their natural surroundings.

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.
