5 key facts about this project
01
Cabins are elevated half a meter above the ground to enhance interaction with the surrounding landscape.
02
The use of board-formed concrete integrates locally sourced earth and stone for a natural aesthetic.
03
Design includes large curved sliding glass doors that frame views of the Serra da Estrela foothills.
04
A newly developed perennial garden attracts local wildlife, enriching the ecosystem around the cabins.
05
Each cabin type is uniquely sized to accommodate individual solitude or group gatherings.

Lirio d'Aqua is a series of cabins designed for meditation, yoga, and holistic treatments, located in the Vale de Moses Retreat near Oleiros in central Portugal. The design reflects a focus on creating tranquil spaces that encourage personal reflection and community engagement. Each cabin seeks to foster a connection with nature, allowing visitors to immerse themselves in a peaceful environment.

Architecture Concept

The design features three different cabins called Pequeno, Medio, and Amplo, which translate to small, medium, and large. This variety allows the space to serve both individuals seeking solitude and groups looking for shared experiences. The overall architecture prioritizes flexibility and adaptability, ensuring that the cabins can accommodate different needs throughout the retreat.

Site Integration

An important aspect of the project is the transformation of a lower stone terrace into a garden, which brings new life to the area. This garden is meant to support native plants and flowers, creating a habitat for birds and pollinators. The addition of greenery enhances the beauty of the landscape and encourages visitors to engage with the natural surroundings throughout the seasons.

Structural Design

Each cabin has a circular shape and is elevated about half a meter off the ground, which helps them blend into the environment. The decks surrounding the cabins provide extra space and promote interaction with the landscape. The use of vertical board-formed concrete, made from earth and stone sourced from the location, gives the cabins a strong connection to the site and reflects the natural textures of the area.

Interior Experience

Inside, the cabins feature a light wood screen that discreetly conceals the bathroom and storage areas, which helps maintain a sense of openness. The careful positioning of each cabin enhances privacy while allowing for views of the nature outside. Floor-to-ceiling curved sliding glass doors invite in natural light and frame views of the Serra da Estrela foothills, encouraging a sense of connection with the landscape.

The cabins also include accessible rooftops that offer opportunities to enjoy the environment, whether it is witnessing the tree canopy or stargazing at night. These elements contribute to the calming and restorative nature of the retreat, providing spaces that support reflection and connection to the surrounding beauty.

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.
