Gross Lettable Area (GLA): Understanding Commercial Property Space in Africa

Gross Lettable Area (GLA) is a key concept in real estate, particularly for commercial and retail property. It refers to the total floor area of a property that is available for lease to tenants, measured from the center of shared walls and excluding common areas like corridors, stairwells, and service areas. Understanding GLA is crucial for property investors, developers, and managers in Africa, as it directly impacts rental income, property valuation, and investment decisions.

What is Gross Lettable Area (GLA)?

Gross Lettable Area (GLA) measures the space that can generate rental income. In retail, office, or industrial properties, it includes:

• Individual shop or office units

• Warehouse or storage areas available for lease

• Spaces leased to tenants within the building

GLA excludes:

• Common areas such as lobbies, staircases, and hallways

• Building amenities like gyms, parking structures, and mechanical rooms

By focusing on the rentable area, investors and landlords can accurately calculate potential income and assess property performance.

Why GLA Matters in Property Investment

Understanding and using GLA provides multiple benefits for property owners and investors:

1. Accurate Rental Calculations
Rental income is often based on the GLA of the property. Knowing the exact rentable space ensures fair lease agreements and transparent financial planning.

2. Property Valuation
Commercial and retail property valuations often depend on GLA, as it reflects the income-generating potential of a building.

3. Tenant Planning
GLA helps property managers allocate spaces efficiently, balance tenant mix, and plan for occupancy levels.

4. Investment Comparisons
Investors can compare different properties using GLA metrics, allowing for informed decisions on rental yield and capital growth potential.

GLA in African Real Estate

In Africa, GLA is especially relevant for:

• Retail Centres and Shopping Malls
  Determining the space rented to shops, restaurants, and service providers, impacting total rental revenue.

• Office Buildings
  Calculating rentable office units for multiple tenants while excluding shared areas.

• Industrial and Logistics Properties
  Assessing warehouses or distribution spaces that are leased to businesses.

Understanding GLA in these property types allows investors to estimate revenue, assess leasing potential, and plan property acquisitions effectively.
