Andrew Dadds grew up in Canada and has worked across Europe and North America. He obtained an Honours Bachelor of Architectural Studies from the University of Waterloo, and a Masters of Architecture from Yale University.

At the Yale School of Architecture, he was awarded the Gene Lewis Book Prize for excellence in residential architecture, and the prestigious Feldman Prize nomination for his work in the Elia Zenghelis studio. His academic work ranges from a fascination for large-scale urban architecture, to more dexterous experiments in drawing and sculpture. Work in the Zenghelis studio included a high-density typological extension to the typical Greek Polykatoikia apartment block. Andrew has also worked with Sam Jacob and Sean Griffiths to propose an architectural compound in Peckham, London, where work in the studio focused on architectural representation though lines and grids.

Prior to joining Oppenheim Architecture, Andrew had worked at firms throughout his co-operative education including Gren Weis Architects in Toronto, Dam en Partners Architecten in Amsterdam, 6a Architects in London, and Lyn Rice Architects in New York.
