At a preview, on Monday afternoon, of City Hall's new green roof, Chris Pommer stood in council chambers and explained some of the thinking behind the multicoloured carpet of vegetation that will soon engulf the podium area underneath Nathan Phillips Square's iconic concave towers. Pommer is a partner at PLANT Architects, the firm that designed the new roof. The project was conceived as "an elaborate series of plantings," he said, gesturing at a large architectural illustration full of minute detail. Elaborate plans are one thing, but we had to wonder just who was doing all this planting.
