I designed this Edmonton roof garden while employed in the office of Carlyle and Associates Landscape Architecture and Urban Design in 1992. The brief was to landscape a roof terrace over a parking garage at the base of a high-rise apartment building, necessitating the placement of planters above the level of the terrace. The planters, constructed using modular precast concrete retaining wall blocks, vary in height according to the depth required for different kinds of vegetation. The retaining wall system permits subtle curves, used here in conjunction with right angled corner blocks and two-tone pavers to create a playful, organic geometric pattern for the garden.
