Lettable Area Plans
Gross Lettable Area Plans (GLA)
A Gross Lettable Area (GLA) survey measures the usable floor area of industrial properties such as warehouses and showrooms, by calculating the space to the external face of the building’s perimeter walls. It includes all enclosed internal areas and is assessed at each floor level by referencing the dominant portion of the outside wall alignment. This provides an accurate representation of the total lettable space within a tenancy.
Gross Lettable Area Retail Plans (GLAR)
A Gross Lettable Area – Retail (GLAR) survey measures the total lettable floor space within a retail tenancy across all floor levels. The area is calculated to the internal finished surface of the external perimeter walls, to the centre line of shared tenancy walls, and to the mall line where a shopfront adjoins a shopping centre mall. This method applies to retail spaces in all settings, including shopping centres and strip retail environments, providing an accurate representation of the tenancy’s usable retail area.
Net Lettable Area Plans (NLA)
A Net Lettable Area (NLA) survey measures the usable floor space of a commercial office tenancy or building in accordance with the Property Council of Australia’s third method of measurement. NLA is calculated to the internal face of the perimeter walls and excludes non-lettable areas such as common spaces, amenities, stairs, lifts, and other service facilities. The total NLA of a building represents the sum of all individual floor areas designated as lettable space.
