Toronto will throw open its doors again this spring as Doors Open 2025 returns the weekend of May 24 and 25, offering free access to over 150 locations across the city. With this year’s theme of play — which we explored in our first Doors Open 2025 report — the two-day celebration reflects how Toronto’s spaces support creativity, physical activity, and connection. Along with a vast swath of buildings opening that will support that theme, 12 architectural firms will be opening their workspaces to the public under the Toronto Society of Architects Open Studio program.
Here is a look at the firms, grouped by the focus of their practice:
Located in a former television studio of the CBC Building at John and Front Streets, DIALOG’s Toronto Studio's 2019 transformation created an open, collaborative environment. The space will host presentations throughout the day, offering visitors a chance to engage with the studio’s projects and design process.
architects—Alliance operates out of the historic Commodore Building, a 1929 Art Deco structure designed by Benjamin Brown, in the heart of the King-Spadina precinct. Visitors will learn how a–A has shaped that transformation through its work on market, rental, and public housing projects across the city.
DTAH’s studio in the Fashion District was recently renovated with expansive views of downtown, including the firm’s own award-winning redesign of St Andrew’s Playground Park directly across the street. The studio offers a glimpse into how DTAH incorporates public realm thinking into its practice and workspace alike.
RAW Design’s new studio at 22 Geary Avenue transformed a former one-storey mechanic’s garage into a two-storey, timber-framed workplace. Visitors will have the opportunity to explore the firm’s focus on community-oriented architecture and innovative material use.
RDH Architects occupies a heritage-listed 1879 commercial row building on Queen Street West, reimagined as a modern design studio. The 4,000ft² space features an open-plan interior with 28 workstations, meeting areas, and a collaboration bar. Visitors will also encounter a two-level atrium at the front of the studio.
Gensler’s Toronto office is located at 150 King Street West in the Financial District. Visitors will get a behind-the-scenes look at projects such as the new Pinterest office interiors, facade work for Holt Renfrew’s flagship store, and upgrades to BMO Field for the 2026 FIFA World Cup.
Brook McIlroy is based in one of two newly constructed mass timber buildings on Sterling Road, part of an emerging creative district near the Museum of Contemporary Art Toronto. As the first tenant in this adaptive reuse office block, their work explores Indigenous placekeeping, public realm design, and community-oriented planning.
HOK’s Toronto studio, located on the 22nd floor of 400 University Avenue, offers panoramic views of City Hall, the Canada Life Building, and the Ontario Courts of Justice. Visitors will experience how the studio environment supports HOK’s wide-ranging work in architecture, interiors, and urban planning.
Atelier Akb operates out of a former 1980s mechanic’s shop that has been transformed into a light-filled studio in a west-end residential neighbourhood. Completed in 2024, the all-white interior features exposed ceiling trusses and resurfaced concrete floors. The renovation reflects the firm’s award-winning approach to modest materials and contemplative design.
People Design Co-op is located on the second floor of a former bank building at the southwest corner of Queen Street East and Carlaw Avenue. The Art Deco–style structure dates to the period following 1924 and now houses a shared creative space with other small businesses. Visitors to the studio will get a glimpse into the co-op’s collaborative environment and socially conscious design practice.
Q4 Architects' studio is perched above the West Don River in Midtown Toronto, with views over the surrounding ravine and tree canopy. Opened in 2022, the space was designed for one of Canada’s largest woman-owned and -led firms, specializing in residential and mixed-use projects that emphasize dignity and inclusivity across affordability levels.
RevelHouse Architecture describes its practice as “Social Architecture,” with a focus on creating immersive, story-driven spaces for clients like Cineplex and Mattel. Their studio showcases projects from around the world and emphasizes how user experience can shape better public and commercial environments. Visitors will learn how storytelling, attraction design, and mixed-use planning intersect in their work.
