This is one of the largest green roofs in Alberta.  It is both a visible and accessible amenity used by hospital staff, patients and their families as a place of respite and contemplation.


Built at the Royal Alexandra Hospital in Edmonton, this healing garden pays homage to Ted & Lois Hole; early advocates of green roof technology and sustainable landscapes. The primary purpose of this green roof is to provide a place for staff, patients and their families, to relax and reflect while enjoying nature in a lush, tranquil environment. 

The size was key to our design, as it allowed our team to include with water, wind, sunlight, stone and vegetation, and to use a variety of green roof systems: extensive, semi-intensive and intensive areas. Moreover, our team developed spaces with different configurations; some areas are meant to allow for solitude and contemplation, while larger areas promote gathering and interaction. 

Our design solution also includes a custom designed containment system, developed with Heavy Industries, a Calgary-based industrial fabrications company.  The choice of plants was based on diversity, colour and textures that highlight the natural flora of Alberta. As a result, this roof is a pleasing and restorative area that provides a sanctuary for its users.
