### Overview

Located in the densely populated outskirts of the Tokyo Metropolitan Area, the Tokyo Sky Gardens project addresses the challenges associated with urban density, space utilization, and community dynamics. The design prioritizes vertical construction, utilizing airspace to provide innovative housing solutions while fostering communal interactions within the urban fabric. The approach includes the creation of a multi-layered urban ecosystem that elevates residential living in harmony with existing infrastructure.

### Architectural Form and Community Integration

The design comprises elevated residential modules supported by structural pillars, which maintain unobstructed street-level activities while enhancing vertical living. This dual-layered urban strategy facilitates accessibility and interaction among residents through integrated communal spaces. An extensive network of sky gardens serves as both recreational areas and evacuation routes, ensuring safety while encouraging social engagement. The intuitive access to these green spaces enhances the overall user experience within the urban environment.

### Materiality and Sustainability Considerations

The selection of materials plays a crucial role in achieving the project's goals. Key structural components utilize reinforced concrete to ensure stability, while steel frameworks provide flexibility. Glass facades optimize natural light and visual connectivity with the surrounding cityscape. Additionally, the incorporation of photovoltaic panels supports sustainable energy initiatives, demonstrating a commitment to environmental responsibility. This careful material selection contributes to the overall resilience of the design, particularly in a region vulnerable to seismic activity.

`
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.
