Gross Area vs. Net Area in Egyptโs Real Estate Market: What Buyers Must Know
Real Estate Market:
Quick Answer (TL;DR)
- Gross area (builtโup area) = everything measured to the outer wall lines plus structural elements and, in some projects, a proportional share of common areas.
- Net area (usable/carpet area) = the space you can live in and furnish.
- In Egypt, gross is usually advertised, while net may be 25โ35% smaller depending on design and wall thickness.
- Always compare the price per net sqm before you commit.

Why This Matters in Egypt
In fastโgrowing markets like Hurghada, Sahl Hasheesh, and Cairo, most developers market units by gross (builtโup) area. It makes listings comparable at a glanceโbut it can mask how much usable space youโre buying. Knowing the difference protects your budget, helps you compare across projects, and avoids surprises on handover.
Key Definitions
1) What Is Gross Area (BuiltโUp Area, BUA)?
The total size of the property, including:
- Exterior and interior walls
- Columns and structural components
- Sometimes, a proportional share of common areas (e.g., corridors, lobbies), depending on the developerโs policy
Example: An apartment marketed as 54 sqm gross includes wall thickness and structural elements within that figure.
2) What Is Net Area (Usable/Carpet Area)?
The real living space inside the unitโwhere you place furniture and move around. It excludes:
- Walls and structural columns
- Shafts and ducts
- Common areas
Rule of thumb: A 54 sqm gross unit often delivers ~36โ38 sqm net (about 25โ35% less than gross, subject to design).
Why the Gap Exists (and Why It Varies)
- Marketing norm: Advertising by gross area is standard practice in Egypt.
- Disclosure: Net area isnโt always highlighted upfront. Ask for it.
- Design & specifications: Thicker walls, larger columns/cores, and faรงade details increase the gap. Resort-style builds along the Red Sea can feature robust envelope systems; highโrise cores in Cairo also affect efficiency.
The Metric that Matters: Efficiency Ratio
Efficiency Ratio = Net Area รท Gross Area
- Typical range in Egypt: 0.65โ0.75
- Higher is better: more usable space per advertised sqm
Fast estimate when the net isnโt disclosed:Net Area โ Gross Area ร 0.65 to 0.75
RealโWorld Example (from buyer conversations)
- Advertised (Gross): 54 sqm
- Net (Usable): 37 sqm
- Difference: 17 sqm โ ~31.5% lower than gross
This 31.5% represents walls/structure and any allocated common areasโnot usable living space.
Price Comparisons: Use Price per Net sqm
Unit A (Hurghada):
- Price: EGP 3,000,000
- Gross: 80 sqm, Net: 56 sqm (70% efficiency)
- Price per gross sqm: 3,000,000 รท 80 = EGP 37,500
- Price per net sqm: 3,000,000 รท 56 โ EGP 53,571
Unit B (Sahl Hasheesh):
- Price: EGP 3,100,000
- Gross: 78 sqm, Net: 60 sqm (77% efficiency)
- Price per gross sqm: 3,100,000 รท 78 โ EGP 39,744
- Price per net sqm: 3,100,000 รท 60 = EGP 51,667
Takeaway: Even though Unit B looks pricier on a grossโsqm basis, it is a better value on a netโsqm basis (more usable space for the money).
Buyer Checklist (EgyptโSpecific)
- Ask for both numbers: Request gross and net area on the same sheet.
- Get the floor plan: With internal room dimensions (width ร depth) and wall thickness.
- Confirm methodology:
- Are measurements to the outer wall, centerline, or inner face?
- Is any share of the common area included in the gross?
- Balconies & terraces: Clarify whether theyโre
- Counted in gross, and
- Counted (fully/partially) in net. Policies vary by developer.
- Compare by net: Recalculate price per net sqm across all shortlisted units.
- Efficiency ratio: Favor units with 0.72โ0.75 when layout and quality are comparable.
- Contract alignment: Ensure your Sale & Purchase Agreement (SPA) and specifications match the plans.
- Onโsite verification: At snagging/handover, measure critical rooms to confirm functional fit (bed sizes, sofa depth, appliance clearances).
Common Questions (FAQ)
Q1: Why do most listings in Egypt show only gross area?
Itโs the market convention. Gross is easy to standardize across a portfolio, but it doesnโt describe livability.
Q2: Are balconies included in the net area?
It depends. Some developers include them (fully or partially), others list them separately. Always confirm in writing.
Q3: Do I pay maintenance on gross or net?
Some communities base standard charges on gross, others on a fixed tariff or a separate โsaleableโ formula. Check the building regulations/SPA.
Q4: Whatโs a โgoodโ efficiency ratio?
0.72โ0.75 is strong for many apartment layouts. Lower ratios arenโt necessarily bad if the building has unique structural or aesthetic featuresโbut you should understand the tradeโoff.
Q5: Can thicker walls be an advantage?
Yes. In Red Sea climates (Hurghada, Sahl Hasheesh), envelope quality can improve comfort and energy useโeven if it slightly reduces net area.
Sample Comparison Table
| Component | Included in Gross? | Included in Net? |
|---|---|---|
| Interior & exterior walls | Yes | No |
| Columns/structural elements | Yes | No |
| Shafts/ducts | Yes | No |
| Proportional common areas | Sometimes | No |
| Rooms (clear usable space) | Yes | Yes |
| Balconies/terraces | Often (policyโbased) | Sometimes (policyโbased) |
Pro tip: When two units have the same gross area but different layouts, the net areaโand how itโs distributed across living room, bedroom, kitchen, and storageโwill determine how โbigโ the home actually feels.

Conclusion
In Egyptโs real estate market, gross area tells you the scale of a property; net area tells you how youโll live in it. Anchor your comparison on price per net sqm and the efficiency ratio. Doing so turns glossy brochure figures into actionable decisionsโespecially in highโdemand areas like Hurghada, Sahl Hasheesh, and Cairo.
