Bruce Hemstock
As a landscape architect who has lived and worked in urban centres across Canada and the United States I decided that the relatively mild climate of the west coast was quite appealing. I have had the pleasure of being part of PWL Partnership for the past eighteen years and together with my colleagues been a part of planning, designing and detailing a lot of Vancouver’s large, waterfront, urban parks and open spaces. A good deal of these landscapes are on the roofs of the various buildings that fill the downtown landscape. This work has illustrated how important green space is to humans and at the same time how little ecological space we leave for the insects and birds. The Vancouver Convention Centre expansion was a turning point in my career. It gave me the opportunity to not only explore the idea of ecological overlays in urban conditions but also design, detail and watch as one was constructed and then matured over time. As a result when I see a roof, I see ecology.
