5 key facts about this project

The meditation capsule project focuses on providing personal spaces for calmness and reflection in the busy urban landscape of Shinjuku, Tokyo. The design seeks to offer individuals a quiet retreat for meditation and relaxation. Inspired by local vending machines and capsule hotels, the structure emphasizes efficient space utilization, allowing users to practice various forms of meditation within a compact environment.

Conceptual Framework

Creating a personal sanctuary amid the chaos is at the heart of this design. Each capsule is designed for one person, allowing for different positions like sitting, lying down, or standing. This flexibility means users can choose what feels best for their meditation practice. Comfort and usability are prioritized, resulting in an environment that supports thoughtful reflection.

Spatial Organization

Inside each capsule, two main areas are clearly defined: an entrance zone and a meditation zone. The difference in elevation between these spaces is an important aspect, reminiscent of the traditional Japanese entryway known as "genkan." This arrangement provides a transition from the outside to an intimate indoor environment. Such organization enhances privacy and promotes a feeling of solitude that is essential for meditation.

Materiality and Sustainability

The choice of materials reflects a connection to both modern practices and cultural heritage. The outer layer is made of wood, linking back to traditional building methods and contributing to a natural look. An aluminum frame supports the structure, featuring sealed windows for efficiency. High-pressure laminate sheets and wooden cladding made from charred pine wood or stain impregnated are also used. These materials add to the visual appeal while supporting sustainable building practices.

Design Details

Functional elements include sliding doors that blend into the frame, maintaining a clean look. Frosted glass allows individuals inside to see outside without being visible to others, enhancing the sense of privacy necessary for meditation. The way light filters through the capsule creates a unique ambiance, providing a meaningful escape in the heart of the urban environment.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
