BDP Quadrangle is one of Canada’s leading architecture, design and urbanism practices. Based in Toronto, Canada, our expertise spans designing for the full spectrum of the built environment including mixed-use, residential, workplace, retail, transit, media, education and health.

We are the North American headquarters of BDP, which was founded in 1961 in the UK as an interdisciplinary design resource. Today, BDP comprises 1,300 people, operating from local studios across three continents. Transcending its growth, the studio’s philosophy has remained the same: to work as a multidisciplinary collective, applying knowledge and expertise to create ambitious projects at every scale.
