While both roof decks and balconies offer outdoor space, they differ in structure and location. A roof deck is an elevated platform built on the roof of a building, often covering a substantial portion of the roof area, and is designed to support weight and facilitate drainage. A balcony, by contrast, is a platform projecting from the wall of a building, supported by columns or console brackets, and enclosed with a railing. Balconies are typically smaller than roof decks and are directly accessible from an indoor space, such as a living room or bedroom. Both extend the living space and provide access to outdoor air and views.
