Definition
Air Space refers to the portion of a property that exists above ground level. This includes the vertical space that is legally considered part of the property. In urban planning and real estate, understanding air space is crucial for developing high-rise buildings, condominium units, and skyscrapers. Owners of buildings and land have rights to this air space, often subject to zoning laws and municipal regulations.
Examples
-
High-Rise Condominium: In a high-rise condominium building, each resident owns the individual unit and the air space that their unit occupies. For example, if someone lives on the 10th floor, they own the air space that their unit takes up within the building.
-
Skyscrapers: Developers of skyscrapers purchase air rights of surrounding low-rise buildings to ensure they can construct taller buildings without obstructing other structures’ air space.
-
Private Residences: A homeowner who builds additional stories or extensions upwards is utilizing their air space, provided they adhere to zoning regulations and height restrictions.
