Designed to evoke the Enso symbol, promoting mindfulness.

The ENSŌ Tokyo Urban Meditation Cabins are located in the busy city of Tokyo, offering spaces for quiet reflection and personal calm. Inspired by the Enso, a symbol in Zen Buddhism that represents enlightenment and wholeness, the design aims to create an environment that fosters peace and contemplation. Each cabin serves as a retreat from the hustle and bustle, encouraging visitors to take a moment to breathe and reflect.

Design Concept and Layout

The layout features an arrangement of circular forms that promotes natural movement within the space. This design reflects Zen principles, enhancing the feeling of connection and unity among users. By creating an inviting atmosphere, the cabins aim to facilitate meditation and restful experiences, allowing people to engage deeply with their surroundings.

Material Selection

The materials used in the construction support both the function and sustainability of the cabins. A sturdy metal covering protects the structure, while solar foil from Heliatek and Kaneka highlights an intention toward renewable energy. Sound-insulating glazing, specifically Trosifol® SC monolayer from Kuraray, ensures privacy while letting in soft light, balancing comfort and illumination.

Bamboo-reinforced rammed earth is the main building material, combining ecological benefits with thermal efficiency. A layer of stationary air, along with rock wool that is 96% recyclable, improves insulation while minimizing environmental effects. The interior walls are finished with backlit tear-resistant shoji paper that is mounted in metal guide rails, creating a calming visual atmosphere that enhances meditation practices.

User Experience and Technology

User interaction is a key consideration in the design. A touch-screen at the entrance enables straightforward reservations and payments, making access to the cabins easy while respecting the need for personal space. This technological feature is subtly integrated, allowing visitors to focus on their meditation without distractions.

The gentle backlighting of the shoji paper creates a soft glow in the interiors. This light casts calming shadows, reinforcing a tranquil atmosphere. The thoughtful design elements work together to connect users to a peaceful experience, fostering a sense of calm that complements the overall goal of the cabins.
