This 3-storey living wall spans the 4th, 5th, and 6th floors at the McMaster Health Centre in Hamilton, ON. It is a key component of the building's ‘feature wall’ (including a water feature and an open staircase/atrium overlooking a green roof) that promotes health by bringing nature into the building and into view of staff and patients alike. Daily exposure to nature is linked to improved mental health, reduced stress, and faster recovery rates after medical procedures. The living wall has approximately 700 tropical plants and a fully automated, multi-zone irrigation system that uses rainwater captured from the building’s rooftop. Irrigation inputs are carefully controlled to provide plants with optimal water and to minimize waste. Maintenance is regularly performed on the entire living wall using a one-person motorized basket suspended from the ceiling.
