The Tokyo Bubble Cloud design addresses the complexities of urban living in a city known for its fast pace and high population density. The approach responds to the challenges posed by constant noise and activity, creating a space for relaxation and introspection. The structure serves as a refuge, allowing individuals to escape the overwhelming stimuli of city life and find a moment of calm.

Concept and Function

The aim is to provide a sanctuary that helps people disengage from the busy environment around them. The Bubble Cloud functions as a flexible space that promotes relaxation and mindfulness. Its inflatable nature allows for easy mobility and adaptation, meaning it can change size according to user needs or specific occasions. The design fosters a sense of safety while encouraging moments of personal reflection.

Design Characteristics

This structure takes on a bubble-like shape, acting as both a physical and psychological barrier from the outside world. It is built to absorb and lessen outside noise, creating a quiet atmosphere inside. Users are encouraged to remove their shoes and take a break, experiencing a sensation of floating away from urban distractions. Such elements contribute to a comforting and thoughtful environment.

Material Considerations

Sustainability plays an important role in the project by using recycled plastics in the structure. This choice reflects a commitment to eco-friendly practices while ensuring the design remains lightweight and functional. The materials not only enhance the overall integrity of the Bubble Cloud but also align with modern principles of environmental responsibility.

Visual Interaction

Transparent portholes allow occupants to view the outside world without giving up their privacy. This aspect creates a balance between isolation and connection to the urban environment. Additionally, the light pollution from the surrounding city serves as an ambient light source within the cabin, enriching the overall atmosphere.

The translucent envelope of the cabin creates an interplay of light and shadow indoors, contributing to a calm and peaceful experience. Each glimpse of the exterior landscape reminds users of the city’s vibrancy while offering a dedicated space for quiet moments.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
