Stacked wooden logs form a complex network of adaptable office and retail spaces, creating a vertical street that harmonizes with the historical context of downtown Tokyo.
5 key facts about this project
01
Wooden blocks are arranged along Cartesian grids, fostering a unique spatial dialogue with the surroundings.
02
Each block functions as a four-story unit, enabling diverse office and commercial configurations.
03
The design incorporates a vertical street, enhancing urban connectivity and pedestrian engagement.
04
Large windows maximize natural light while maintaining visual harmony with the urban landscape.
05
The structure references Metabolist principles, presenting a living organism that adapts to community needs.

The recent development on the site of the former Nakagin Capsule Tower in downtown Tokyo marks an important shift in the interpretation of Metabolist architecture. The design focuses on adaptability for modern work environments while recognizing the historical significance of the earlier structure. It combines innovative thinking with a sense of continuity, creating a new architectural landmark for the city.

Design Concept and Structure
The project features a series of rectangular wooden blocks organized along Cartesian grids. This arrangement fosters a connection with the surrounding urban environment and pays respect to the legacy of the Capsule Tower. By moving beyond the traditional modular approach, the design introduces a new structural concept that highlights flexibility and interconnectedness.

Spatial Organization
Each wooden block is designed as a four-story unit, resembling a large "wooden log." This design choice shapes the interior while ensuring structural stability. The logs stack to form a complex network of spaces, incorporating solids and voids. This arrangement allows various office configurations, supporting both shared and private workspaces alongside commercial areas.

Urban Integration
The project creates a vertical street that contributes to the lively character of downtown Tokyo. Retail and dining spaces are thoughtfully distributed throughout the building, from the ground level to higher floors. This multi-level approach encourages foot traffic and interaction, enhancing the overall experience for visitors and residents alike.

Community Engagement
Inspired by the idea of organic growth from Metabolist theory, the building functions like a living organism. It aims to provide a sustainable environment that meets the evolving needs of the community. With a mix of flexible workspaces and public areas, the design promotes collaboration and emphasizes the significance of community in urban development.

Large windows on the building's façade allow ample natural light into the interior spaces, creating a bright atmosphere. This feature not only enhances the experience of the occupants but also maintains visual harmony with the surrounding urban landscape.

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.
