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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
