Ben Checkwitch developed a fascination with architecture while working on construction sites, which eventually lead him to pursue a degree from the School of Architecture at the University of Manitoba. After moving to British Columbia, he entered the field of Naval Architecture working as a draftsman designing yachts. It was in there that he further honed his construction skills while building a home on a small and relatively remote Gulf Island.

After earning his Masters of Architecture from Dalhousie University, and apprenticing in Oslo, Norway with the architectural firm Narud Stokke Wiig, Ben began his professional practice in New York with renowned architectural firms Rafael Viñoly Architects and later Gluckman Mayner Architects. It was in New York that he developed his expertise in the detailing of glass curtainwall and building envelope systems and the design of museum and gallery spaces. Ben has contributed to prominent projects including The Bronx County Hall of Justice, The Austin Museum of Art, The Museum of Contemporary Art in San Diego, a private gallery/studio for the artist Richard Serra, and several high-end residential projects. In 2002, he founded Ben Checkwitch Design (BCD), a Manhattan-based firm that designed a broad spectrum of residential, commercial, retail and furniture projects that earned him distinction in I.D. Magazine’s Annual Design Review in 2003. His work has also been recognized by the Architectural League of New York, where he has lectured and exhibited as a winner of the Young Architects Forum.

In 2008 he began collaborating with David Poiron on various projects, most notably the award-winning Nanaimo cruise ship terminal building, which led to the formation of Checkwitch Poiron Architects in 2012.

Brett MacIntyre (Kuut'a K'ii)

Bachelor of Arts (History in Art) – University of Victoria 2008
Bachelor of Environmental Design Studies – Dalhousie University 2010
Master of Architecture – Dalhousie University 2012
Architectural Institute of British Columbia, Intern (IA AIBC)

Brett’s interest in architecture is rooted in his work in the field of construction in his hometown of Fernie, BC. Moving to the west coast allowed him to re-connect with his Haida heritage and develop his fascination with Indigenous art and culture while studying Art History at the University of Victoria. This fascination carried through into his architectural studies, where his graduate thesis, “Memory and Myth: Storytelling as a Design Tool for a Youth Camp in Haida Gwaii” was awarded the Dalhousie School of Architecture Thesis Prize.

Following graduation, Brett was awarded the Canada Council for the Arts Prix de Rome for Emerging Practitioners, enabling him to travel to Northern Scandinavia to study with the Saami, an indigenous group native to the area. His exhibition, “Lessons from Lappland: Pragmatism, Temporality and the Challenge of Icons in Indigenous Architecture” further developed his goal of fostering meaningful discussion around the creation of sincere modern indigenous architecture.

Brett has worked in offices across Canada, from PWGSC in Halifax, Nova Scotia, Architecture ATB in Edmonton, Alberta, and Perkins + Will in Vancouver, British Columbia. He has experience with a wide variety of commercial, residential and institutional projects, as well as large scale master planning. Brett currently lives in Vancouver, British Columbia and is registered with the AIBC as an intern architect.
