Suspended units supported by modular platforms and enhanced by green roofs redefine underutilized urban spaces in Vancouver, providing affordable housing that integrates functionality with community-oriented design.
5 key facts about this project
01
Suspended housing units create unimpeded vehicle access beneath.
02
Green roofs serve as urban pathways for enhanced connectivity.
03
Community spaces incorporate retail and playground areas.
04
Modularity allows flexible unit configurations for diverse needs.
05
Fiber cement tiles provide durability in high-traffic areas.

Located in Vancouver, the design addresses the urgent need for affordable housing in the city, which faces challenges due to its growing population and housing demand. The project reimagines underused urban spaces, especially those adjacent to major transport infrastructure such as bridges and SkyTrains. The overall concept seeks to create a community that is accessible, functional, and sustainable, integrating living spaces with the urban environment.

Modular Design Approach

The design employs a modular approach that utilizes suspended platforms to elevate housing units. This strategy maximizes land use by pushing living spaces upward, allowing vehicles to move freely below. It not only addresses space constraints but also accommodates changing living needs. This flexible design can adapt over time as community requirements evolve.

Integration of Green Spaces

Green roofs are a notable aspect of the project. They enhance both the beauty and functionality of the housing units, serving as green pathways for train passengers. This element contributes positively to the city’s ecology, encouraging biodiversity and enhancing the environment. The careful combination of nature with built structures emphasizes the importance of greenery in urban areas.

Community-Centric Elements

The design goes beyond providing simple living spaces. It includes communal areas that promote social interaction among residents. By incorporating shops and playgrounds in the redesigned spaces beneath the bridge, the project enhances community engagement and activates the area. The focus on communal facilities reflects a commitment to serve not only the residents but the wider neighborhood.

Materials and Construction Techniques

Selected materials for the units include wooden floors, fiber cement tiles, and steel. Each material was chosen for its durability and suitability for urban settings. Wooden floors add warmth, while fiber cement tiles are practical for high-traffic areas. Steel offers structural strength, ensuring stability for the elevated units and balancing the overall design.

In this design, the concept of sustainable urban living takes form through thoughtful planning and execution. The integration of functional details and communal spaces creates a model for modern urban environments that can adapt to the needs of their inhabitants.

`
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.
