Slack Toronto Office By Dubbeldam Architecture + Design - Sheet2

Each office occupies a former industrial building with interiors that honour the property’s legacy, renew its productivity, and reflect Slack’s values of empathy, solidarity, and craftsmanship.

Set in a former knitting and textile factory in the heart of downtown Toronto, three storeys within the interior of this mid-rise brick and beam building were redesigned to meet all the needs of a twenty-first century tech company, inspired both by the building’s heritage and the company’s work culture.

The design team drew from a “threads of communication” concept using linear geometries throughout the space, such as continuous angular light fixtures and coloured networking cables running through the length of the office on the ceiling and walls. These enliven the space in an homage to the lines of yarn that were used in the mechanized knitting process, while also referencing the communication service of the messaging application itself. In the reception area, the design team worked with long-term collaborator Kathryn Walter of Felt Studio who wrapped diagonal strips of industrial felt along the walls and ceiling, creating a warm and inviting environment as soon as you step into the office.

Each zone corresponds to a single colour that comprises Slack’s branding, reinforcing company identity while also providing visual interest and relief to the otherwise yellow tones of the brick and wood interiors. Meeting rooms are uniform yet each unique, owing to their bold and varied colour scheme.

The angular light fixtures appear to thread through the ceiling, knitting workspaces and meeting rooms together. The large communal cafe picks up on the linear theme again with its white and wood diagonal slat finish. According to principal Heather Dubbeldam, “The interior spaces are varied enough to meet the functional requirements of 140 employees, but they also bring a sense of continuity and community to the workplace. The result is a fresh take on an old space that is serious about work while offering a playful and comfortable space for its employees to succeed”.
