The Property Council of Australia Method of Measurement for Lettable Areas is an indispensable tool for accurately calculating lettable areas in commercial, industrial and retail premises for property owners. Formerly known as the BOMA Method of Measurement this is now the definitive guideline for measuring floor space area in leased premises and ensures a consistent approach is taken to calculating lettable areas across a range of building or industrial property types for property owners.


The guidelines define three types of area calculation used in commercial leases;

  1. Gross Lettable Area – GLA – for industrial buildings, showrooms and freestanding supermarkets.  

  2. Net Lettable Area – NLA – which is used for office buildings and tenancies.  

  3. Gross Lettable Area Retail – GLA-R for retail tenancies in shopping centres, commercial buildings and strip shops.


Calculating the lettable area of a tenancy can be difficult as all buildings are unique and each has its own unique set of conditions. While the Property Council Guidelines provide an excellent job of defining the criteria for calculating areas it is impossible to cover every single eventuality in built environments. This is where extensive experience and knowledge from a qualified surveyor comes into play to deliver accurate lettable area measurements.

The Property Council of Australia champions the interests of more than 2000 member companies that represent the full spectrum of the industry, including those who invest, own, manage and develop in all sectors of property, creating landmark projects and environments where people live, work, shop and play.
