Toronto Affordable Housing 2021 is designed to address the pressing need for affordable living spaces in an urban environment. Located in Toronto, the project moves away from typical images of monotonous apartment buildings. It aims to create a welcoming community through thoughtful design and an emphasis on interaction among residents. The overall concept integrates residential units with shared spaces, enhancing both functionality and connection within the city.

Podium Building Typology

The design employs a podium building typology, where distinct upper and lower segments are arranged within a socket-insert layout. This arrangement allows for the use of prefabricated residential units, which simplifies construction while reducing costs. The positioning of these units maximizes natural light, which is essential for providing comfort and lowering energy use, especially in Toronto's changing climate.

Community-Centric Design

At the heart of the design is the concourse, which acts as a central space for residents to gather. It thoughtfully connects to existing apartments nearby and includes a community garden that encourages sustainable living practices. The addition of a junior-sized hockey rink promotes recreational activities, enhancing social interaction and a sense of belonging among residents.

Environmental Considerations

The layout of the residential units is aligned with the sun's path, ensuring ample sunlight enters living spaces. A double-skin facade with integrated photovoltaic technology helps insulate the building during the winter and shades it in summer. This approach contributes to energy efficiency and supports environmental sustainability, addressing modern challenges in housing design.

Urban Integration

The arrangement of the units features a shared sunspace, blending indoor and outdoor experiences. This design encourages connections to the vibrant street life of Toronto, allowing residents to engage with their surroundings. The facade showcases an interesting mix of volumes and terraces that invite interaction, offering private outdoor areas while fostering a sense of community that is responsive to urban life.

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.
