Built with Cross Laminated Timber and designed as octagonal structures, the residences incorporate vertical farming and green facades, addressing urban housing needs while creating a community-focused living environment above city intersections.
5 key facts about this project
01
Octagonal residence design maximizes space efficiency at urban intersections.
02
Cross Laminated Timber construction reduces environmental impact and enhances stability.
03
Rooftop gardens promote communal interaction and support local food production.
04
Adaptable facade modules allow residents to control privacy and light exposure.
05
Vertical farming installations enhance sustainability within residential environments.

The housing crisis in Vancouver prompts the need for innovative solutions in urban design. By focusing on the use of urban intersections as residential areas, the project aims to turn previously underutilized spaces into functional homes. The design elevates residential units above busy streets, maximizing space without hindering pedestrian movement or community interaction.

Residential Configuration

The layout features octagonal residences that can hold 4 to 8 modular units per floor. This modular structure allows for various unit sizes and arrangements, adapting to the unique dimensions of the city’s roadways. The design emphasizes a clear division between public, semi-public, and private spaces, allowing residents to engage with one another while also having their own personal areas.

Integration of Green Spaces

Green spaces play a vital role in this design, addressing the urban heat island effect common in downtown settings. The project includes vegetated roofs and a green facade system, enhancing the overall appearance and sustainability of the buildings. These green elements aim to improve urban livability and provide residents with a connection to nature within the city.

Unit Types and Flexibility

Standard floor plans include different types of units to cater to a broad range of residents. Studio apartments are designed for young students or low-income individuals, offering accessible living spaces. In contrast, larger units accommodate 2 to 3 residents, suitable for young families. Each unit has access to terraces, ensuring that light and outdoor space are integral parts of the living experience. Adaptable facade modules offer residents control over their privacy and light.

Construction Materials

Materials chosen for the project reflect its commitment to sustainability. Cross Laminated Timber serves as the main structural component, providing both stability and a lower environmental footprint. Additionally, wooden slabs made from 100% recycled wood support the goal of cradle-to-cradle development, ensuring that the building process respects ecological principles.

The design includes a rooftop garden that acts as a communal space where residents can gather. This feature not only encourages social interaction but also integrates elements of nature into daily life, enhancing the living experience amidst a bustling urban environment.

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.
