Mizu Hospice is located in Oura, Uwajima, Ehime, Japan. It serves as a place for healing that connects individuals with their community and their environment. The design focuses on the cycles of life, using thoughtful layouts and cultural elements to create spaces that inspire reflection and encourage interaction.

Architectural Concept

The design reflects the continuous flow of life, showcasing themes of birth, death, and rebirth. Circular forms and open spaces guide movement while allowing for contemplation. This approach offers each visitor a personal journey within a collective experience. The layout encourages people to engage deeply with both the architecture and each other.

Chapel Design

At the heart of Mizu Hospice is the chapel, built with solid concrete walls that provide strength and stability. Large windows invite natural light into the space, making it feel warm and welcoming. The roof is designed as a thin-shell structure, inspired by the folds of a kimono. Its gaps create a dynamic flow of light throughout the interior, casting gentle patterns on the walls and enhancing the feeling of peace.

Community and Gathering Spaces

Several communal areas are designed to promote interaction among visitors. The restaurant emphasizes shared meals, supporting the notion of community while offering traditional Japanese cuisine. Additional gathering spaces and a tea ceremony area encourage mindfulness and cultural engagement. These elements help create a sense of belonging for everyone who visits.

Landscaping and Water Elements

The gardens play a vital role in the overall experience at Mizu Hospice. The Chapel Garden, Spiral Garden, and Central Zen Garden, which features a cherry blossom tree, contribute to a calming atmosphere. These gardens are designed to support mental and emotional well-being. The project also includes a water collection system that redirects rainwater to various features on the site. This focus on sustainability enhances the peaceful environment while connecting nature with architectural design.

In the chapel, sunlight filtering through the roof’s gaps creates ever-changing patterns on the walls, providing moments for pause and reflection. This design detail invites guests to experience calm and contemplation as they move through the space.

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.
