The outer walls of the Canada Water library are clad in aluminium sheets, anodised to have a light bronze tint with sequined perforations. The wavy aluminium skin gives the surface of building a creased and ripple effect. The architects inspiration for the skin came from the near by lake. As a result of the close proximity of the lake to the building, the ripples from the lake reflect onto the building creating a double ripple outcome. This is visible only on the lake side facade and when there is sunshine. The double ripple is shown in the video taken on a sunny day.
