Les is committed to the idea that urban design, city building and architectural excellence all play vital roles in enhancing the quality of community life. With a Master of Architecture degree from the Massachusetts Institute of Technology, as well as two BSc degrees (in Arts & Design and Mathematics), he brings a disciplined problem-solving approach to every new architectural challenge, proposing solutions attuned to each client’s unique needs and aspirations. Les has helped shape Quadrangle’s success through his work in a broad range of areas, from innovative residential development, to the adaptive reuse of existing structures, to the creation of dynamic environments for ideas-based entrepreneurial companies – including broadcast and media facilities. He has also received international attention for the Green Ribbon, his audacious proposal to build a seven kilometre green roof and park over Toronto’s elevated Gardiner Expressway. A frequent speaker at professional conferences, Les has taught at the University of Toronto’s Faculty of Architecture, Landscape and Design, and has been a visiting critic at the University of Waterloo and York University.
