By In the world of commercial real estate, understanding Net Lettable Area (NLA) is essential for landlords, tenants, investors, and property managers. The NLA determines the usable space within a building that can be rented or leased, making it a critical factor in property valuation, lease agreements, and rental income calculations.

Let’s dive in and explore everything you need to know about Net Lettable Area (NLA)!
What is Net Lettable Area (NLA)?
Definition of Net Lettable Area (NLA)
Net Lettable Area (NLA) refers to the total usable area within a commercial building that can be leased or rented to tenants. It includes offices, retail spaces, and warehouse areas but excludes common areas like stairwells, lobbies, and service areas.
NLA is the area that tenants actually pay for in a lease agreement.
- What Spaces Are Included in NLA?
- Office spaces (workstations, meeting rooms, private offices)
Retail units (shops, showrooms, display areas)
Warehouse or industrial spaces (storage, manufacturing areas) - What Spaces Are Excluded from NLA?
- Shared hallways and corridors
Stairwells and elevators
Public restrooms and service areas
Mechanical and utility rooms
Example: If a commercial building has a total floor space of 5,000 sqm but 1,000 sqm is occupied by stairwells, hallways, and mechanical rooms, the Net Lettable Area (NLA) would be 4,000 sqm.
How to Calculate Net Lettable Area (NLA)?
Net Lettable Area Formula
NLA=Total Floor Area−Common Areas (Non-Leasable Spaces)\text{NLA} = \text{Total Floor Area} – \text{Common Areas (Non-Leasable Spaces)}
- Step-by-Step Guide to Calculating NLA:
Measure the total building area.
Identify and subtract non-lettable areas (hallways, lifts, staircases).
The remaining usable tenant space is the Net Lettable Area (NLA).
Example Calculation:
- Total Building Area: 10,000 sqm
- Non-Leasable Spaces (lobbies, hallways, mechanical rooms, etc.): 2,500 sqm
- Net Lettable Area (NLA):
10,000−2,500=7,500 sqm (NLA)10,000 – 2,500 = 7,500 \text{ sqm (NLA)}
NLA Measurement Standards
- International Property Measurement Standards (IPMS) provide standardized methods for calculating NLA.
In Australia, NLA is measured using Property Council of Australia (PCA) guidelines.
In the UK, NLA is defined by the Royal Institution of Chartered Surveyors (RICS).
Pro Tip: Always refer to local real estate regulations for precise measurement standards.
NLA vs. Gross Floor Area (GFA) vs. Usable Floor Area (UFA)
| Metric | Definition | Includes | Excludes |
| Net Lettable Area (NLA) | The rentable area available to tenants | Offices, shops, storage areas | Common areas, service spaces |
| Gross Floor Area (GFA) | The total building footprint, including all spaces | Entire building (lettable + non-lettable areas) | Outdoor spaces |
| Usable Floor Area (UFA) | The space physically occupied by a tenant (excluding walls, columns) | Workspaces, furniture areas | Walls, structural elements |
NLA is important for rental income, while GFA is used for overall property valuation.
Importance of NLA in Lease Agreements
Why NLA Matters for Landlords & Tenants
- Determines rent pricing – Tenants are charged based on the NLA they occupy.
Affects lease negotiations – More efficient layouts maximize NLA.
Impacts property valuation – Higher NLA means higher rental income potential. - Lease Types Based on NLA
- Gross Lease: Rent includes all costs (utilities, maintenance, etc.).
Net Lease: Tenant pays rent + additional expenses based on NLA.
Tip: Always check lease agreements for accurate NLA calculations to avoid overpaying.
How NLA Affects Rental Pricing & Property Valuation
Rent Calculation Using NLA
Annual Rent=NLA (sqm)×Rental Rate per sqm\text{Annual Rent} = \text{NLA (sqm)} \times \text{Rental Rate per sqm}
Example:
- NLA: 500 sqm
- Rental Rate: £50 per sqm per month
- Total Monthly Rent:
500×50=£25,000500 \times 50 = £25,000
- Higher NLA = More rental income potential for landlords.
Future Trends in NLA & Commercial Leasing
- Flexible Workspaces – Businesses are optimizing NLA by using shared office spaces.
Smart Building Design – Architects focus on maximizing NLA for better tenant value.
AI & Digital Measurement – Drones and AI help calculate NLA with high precision.
The future of commercial real estate will prioritize efficient use of NLA to maximize returns.
Conclusion
Understanding Net Lettable Area (NLA) is essential for landlords, tenants, and real estate investors. It directly affects rental pricing, lease agreements, and property valuation.
Key Takeaways:
- NLA is the usable space in a building that tenants pay rent for.
NLA = Total Floor Area – Non-Leasable Spaces.

FAQs
1. What does Net Lettable Area (NLA) mean?
NLA is the usable space in a commercial property that can be rented to tenants, excluding hallways, lobbies, and service areas.
2. How is NLA calculated?
NLA=Total Floor Area−Common Areas\text{NLA} = \text{Total Floor Area} – \text{Common Areas}
3. What is the difference between NLA and GFA?
NLA includes only rentable space, while GFA includes all spaces, including common areas and mechanical rooms.
4. Why is NLA important for lease agreements?
NLA determines how much rent a tenant pays and helps landlords set fair rental rates.
5. Can NLA change over time?
Yes! Renovations, layout changes, and new measurements can adjust the NLA of a building.
