Difference between GLA and LFA

Looking for the perfect office? Don’t overlook GLA and LFA! When renting office space, it’s crucial to understand how the gross lettable area (GLA) and the lettable floor area (LFA) impact how much usable space you actually get. Stay informed to avoid surprises — and to find the workspace that truly fits your needs.

Looking for the perfect office space? Pay attention to GLA and LFA!

When renting office space, there’s more to consider than location and monthly rent. Key factors like Gross Lettable Area (GLA) and Lettable Floor Area (LFA) play a crucial role in how much usable space you actually get. You don’t want any surprises — like finding out your office feels smaller because shared walls and technical voids were counted in. Let’s dive into the world of office measurements so you can make a smart, informed decision.

What is Gross Lettable Area (GLA)?

GLA refers to the total area of the building, including everything from walls to stairwells — and even outdoor spaces. It’s the full physical size of the building. But beware: GLA also includes elements you don’t directly use, like staircases, lift shafts, and parking facilities. Every inch is counted — even between two interior spaces, the measurement goes to the center of the dividing wall. This can impact how your office layout actually looks, so it's good to be aware.

Why Lettable Floor Area (LFA) matters

LFA is the part of the office space you can actually work in. It’s the usable area — excluding things like lift shafts, stairwells, or technical service rooms. In short: it’s what you and your team can occupy day-to-day. If you're optimizing for space and budget, the LFA is the number to focus on. It helps you understand how efficiently you’re using the space you’re paying for.

The fine print behind LFA

Some spaces you don’t see right away still affect the LFA calculation. If your office has lots of service shafts or a large atrium, those aren’t included in the LFA. So the usable space might feel smaller than expected. Also important: tenants are usually assigned a share of common areas — like receptions or shared meeting rooms. These are proportionally added to your personal LFA.

Outdoor areas and their impact on GLA

If your company values fresh air or stunning views, outdoor spaces like balconies and terraces matter. These are included in the GLA — whether covered or not. This can increase a building’s perceived value. But keep in mind: not every outdoor space adds practical value to your daily operations.

Conclusion: GLA and LFA make a big difference

If you’re considering renting an office, it’s essential to understand both the GLA and LFA. These two numbers tell you how much space you’re actually paying for — and how much of that you’ll really use. Avoid paying for unusable areas or ending up short on room.
