Using a bark roof and a pine structure, the design emphasizes natural materials and reflects on themes of life and rebirth, serving as a contemplative space for meditation and self-reflection.
5 key facts about this project
01
The bark roof minimizes ecological impact through natural materials.
02
The design utilizes traditional joinery techniques without any hardware.
03
Pine is the primary material, promoting a strong connection to the surrounding landscape.
04
An upper level opens to four sides, enhancing views and natural light.
05
Meditative spaces focus on the interplay of water, fire, and light elements.

The architectural design explores the relationship between life, death, and rebirth, situated in a natural context that enhances its themes. It serves as a space for reflection, inviting users to engage with nature while fostering a sense of inner peace. The overall concept highlights the transition between different states of understanding, using both darkness and light to shape the visitor’s journey.

Concept and Experience

The design embodies the cycle of existence, emphasizing the connection between humanity and the environment. Upon entering, visitors find themselves enveloped in darkness, representing a separation from the outside world. This initial moment encourages reflection, allowing individuals to prepare for an encounter with the fundamental elements of life: water, fire, and light. Progressing through the space, visitors experience a thoughtful journey that transitions from contemplation to enlightenment.

Spatial Arrangement

Inside, the layout is carefully organized to enhance the contemplative experience. After a time spent in darkness, individuals ascend to a higher level where previously hidden views unfold. This reveals new perspectives on both the outside landscape and their inner thoughts. Climbing upward symbolizes a journey toward understanding, connecting the physical movement within the structure to the philosophical themes of rebirth and renewal.

Material Selection and Sustainability

Natural materials play a crucial role in the design, reinforcing its connection to the surrounding environment. Pine trees are utilized for various elements of the structure, while bark serves as the roof. The outer wall is composed of combined scraps, highlighting a commitment to sustainability and minimizing environmental impact. Traditional joining methods, commonly found in Buddhist architecture, are employed to ensure materials can be reclaimed and returned to the earth when needed.

Environmental Integration

The building effectively responds to its environment. The upper floor features deep eaves that control sunlight, which helps maintain a comfortable atmosphere inside. A SHOJI screen further enhances flexibility and provides excellent insulation, connecting the space to the outdoors. This focus on environmental responsiveness emphasizes the intent to harmonize with nature and create a peaceful area for self-reflection.

Overall, the design expresses the themes of life and rebirth. It presents a structure that promotes mindfulness through its thoughtful architectural elements and layouts.

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.
