Display window definition
Defines a display window as an area of glazing at the external perimeter for displaying products or services, positioned at access level adjacent to pedestrian thoroughfares. Specifies conditions for glazing height limits and exceptions.
Display window – an area of glazing, including glazed doors, intended for the display of products or services on offer within the building, positioned at the external perimeter of the building and at an access level and immediately adjacent to a pedestrian thoroughfare. Where there is a workspace within one glazing height of the perimeter, it should not be considered to be a "display window". Glazing that extends to a height of more than 3 m above an access level should not be considered as part of a display window except – (a) where the items on display require a greater height of glazing; (b) in existing buildings, when replacing display windows that already extend to a greater height; or (c) where windows of a greater height are required as a result of a planning condition.
