Hub House is an initiative located in Toronto that addresses the pressing need for affordable housing in the city. It focuses on transforming vacant and abandoned plots into livable residential spaces, utilizing a modular design approach that emphasizes flexibility and adaptability. The project aims to change the perception of affordable housing by integrating it more closely with the community, alleviating concerns often raised during similar developments, and fostering a vibrant, interconnected neighborhood.

Modular Design

The design utilizes a modular construction system that allows for prefabricated components. This approach helps to speed up the building process while keeping costs down. Residential units are designed to be interchangeable, with options for studio and two-bedroom layouts, providing the potential for customization based on changing community needs. This flexibility ensures that the spaces can adjust to demographic shifts over time.

Community Engagement

A key feature of Hub House is the multi-functional space on the ground floor. This area serves as a central hub for community interaction, designed to bring residents together. Throughout the year, it can host various activities, including local markets and seasonal celebrations. By creating a shared space for social interaction, the design encourages connections among residents and contributes to a strong sense of community.

Materiality and Sustainability

The choice of materials significantly influences the project's environmental impact and functionality. Timber is the primary construction material, valued for both its cost-effectiveness and sustainability. Using locally sourced and prefabricated materials helps reduce the ecological footprint and streamline construction. Cork is used for insulation, which improves energy efficiency and enhances indoor air quality. Polycarbonate windows provide a lightweight and recyclable alternative to traditional glass, aligning with the project's sustainability objectives.

Architectural Expression

The visual language of Hub House reflects a modern yet practical design. It combines public and private spaces, ensuring residents have access to essential amenities while maintaining comfort and security. The façade showcases a pleasing arrangement of forms and proportions, highlighting the modular nature of the structure while fitting well into the urban environment.

The project emphasizes a welcoming atmosphere that balances both community and individual needs. Each element works together to create a space where residents can thrive, underscoring the importance of thoughtful design in everyday living.

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.
