Cantilevered forms extend outward, framed by vibrant red elements and warm wood textures, creating an educational hub that redefines urban learning spaces while bridging connections to the nearby garden.
5 key facts about this project
01
Cantilevered design enhances spatial dynamics while providing shaded outdoor areas.
02
Vibrant red accents are deliberately integrated to draw user attention and create focal points.
03
Cross-laminated timber panels contribute to both sustainability and structural integrity.
04
Charred wooden shingles offer fire resistance while adding texture and character to the facade.
05
An open atrium facilitates movement and interaction among diverse user groups.

## Overview

Located at a vital intersection in Tokyo, the Pop Lab integrates visual, cultural, and spatial connections between the adjacent Japanese Garden (Tokyo Green Palace) and educational facilities, particularly a high school. The intent is to create a multifunctional hub that harmonizes modern operational needs with elements of traditional Japanese aesthetics, supporting an engaging environment for learning and community interaction.

### Spatial Dynamics and User Interaction

The architectural design emphasizes interconnectivity through layered volumes and vibrant color palettes, enhancing the user experience by promoting both indoor and outdoor activities. The structure's dynamic layout encourages exploration, allowing users to transition from the bustle of urban life to serene garden settings. Key functional spaces, including lecture rooms, exhibit halls, cafeterias, and libraries, are designed to accommodate various educational and communal activities, fostering a sense of community engagement.

### Materiality and Structural Considerations

Material selection plays a critical role in defining the character of the project. Transparent glass facades maximize natural light, while steel provides the structural integrity necessary for the bold cantilevered forms. Concrete elements offer spatial mass, complemented by the warmth of wood finishes that introduce traditional aesthetic qualities. The building's cantilevered structures create shaded outdoor areas, enhancing visual accessibility and inviting interaction between the architecture and its surroundings. The combination of these materials helps to establish a strong connection with the adjacent garden, enhancing the experience of nature through architectural forms.

`
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.
