About Us

Empowering Architecture

At Kearns Mancini Architects, we bring our experience, design skills and technical expertise to create spaces that delight and transform learning, living, working, care and hospitality facilities. We create inspired, iconic architectural visions by clearly identifying our clients’ needs and aspirations, as well as their cultural and market values. We seek out and drive the innate transformative qualities of architecture in a way that will inspire and empower our clients and their communities. Kearns Mancini Architects understands the significance of Passive House design methodology. True sustainability comes from measures and practices we make to limit our impact on the earth, allowing us to live as we do today without continued long-term effects on the planet. We collectively, have been working on Passive House since 2009.



We are honoured to have received numerous awards that recognize our commitment to create spaces that will empower our clients. Here are a few...

We're living in a time of incredible consumption, and everything's about economics and everything's about cash flow, and I think Jonathan Kearns has an ability to stand away from that stuff and feel something that motivates him. He's motivated to do his work in a way that I think a lot of architects and a lot of designers aren't. What I'm saying is that he's got a depth of emotion and feeling, and it comes out.
Bruce Kuwabara
Chair of the Board of Trustees, Canadian Centre for Architecture
The Canadian Canoe Museum defers to the landscape and the need to integrate with it, as opposed to standing out like a Bilbao. It’s not architecture as an object, but rather architecture linked to experience. The most significant thing beyond the integration in the landscape is the experience from within, and how the museum frames the view to the outside. It’s a very soft and generous approach to building.
Manon Asselin
