Net and Gross Area When Buying Property in Turkey
Learn the difference between net and gross property areas in Turkey, how usable apartment space and shared areas are calculated, and what to check before signing a purchase contract.
When buying an apartment in Turkey, it is not enough to look at the price, number of rooms, and property location. You also need to understand the area you are paying for and the actual space you will receive inside the apartment.
Turkish real estate advertisements often show a gross area that is larger than the usable interior area. This can create a difference between the buyer's expectations and the actual property they receive.
In this guide to net and gross property area in Turkey, we will explain the difference between net area and gross area, the meaning of the Turkish terms Net Alan and Brüt Alan, and how to calculate an apartment's area in Turkey in square meters.
We will also clarify the difference between an apartment's gross area and the general gross area, which includes its share of the building's common areas, and explain what you should check in property advertisements and sales contracts before paying a deposit or signing an agreement.
This information will help you assess the apartment's actual area, compare properties more accurately, and avoid paying a high price for space that is not part of your private interior living area.
What Is the Difference Between Net and Gross Area in Turkey?
Understanding the difference between net and gross area in Turkey is one of the most important things buyers should know before choosing an apartment. The area stated in a real estate advertisement may not reflect the space you can actually use inside the property.
In Turkish real estate terminology, Net Alan refers to net area, while Brüt Alan refers to gross area. Turkish zoning regulations define how these areas are calculated, distinguishing between the gross area of an independent section and the general gross area, which includes its share of common areas.
What Do Net Alan and Brüt Alan Mean in Turkey?
Net and gross areas in Turkish real estate differ according to the measurement method and the applicable legal definition. They can be explained as follows:
- Net Area (Net Alan): The interior area of an apartment measured between its walls, excluding certain elements such as columns, some technical spaces, and open balconies, depending on their nature and the applicable legal definition. It is the most important measurement for determining the actual usable interior space.
- Gross Area (Brüt Alan): Calculated according to the boundaries of the independent section and the method used to account for walls and structural elements. It is therefore usually larger than the net area and should be distinguished from the general gross area, which includes the apartment's share of common areas.
The Difference Between Brüt and Net in Turkish Real Estate in Numbers
Suppose a property advertisement lists an apartment with a gross area of 120 m² and a net area of 95 m². The difference is 25 m², meaning that the net area represents approximately 79.2% of the gross area. This percentage is illustrative, as the ratio varies from one apartment to another depending on the area calculation method.
It is important to understand that the difference between the two measurements does not necessarily represent entirely wasted space. It may be related to wall thickness and other elements included in the gross-area calculation. It may also depend on the type of area stated in the advertisement.
Why Does Net Area Differ from Gross Area?
Several factors cause the net area of apartments in Turkey to differ from their gross area. The most important include:
- Internal and external walls: Parts of these may be included in the gross-area calculation according to the applicable regulatory boundaries.
- Columns and structural elements: These are not treated in the same way when calculating net and gross areas.
- Balconies and terraces: Their treatment depends on the regulatory definition and the nature of the area. They are not automatically considered interior space.
- Common areas: Corridors, staircases, and elevators may be included proportionally in the general gross area, rather than in the apartment's area alone.
When comparing two apartments in Istanbul, Ankara, or Antalya, make sure that the area figures in both advertisements are calculated using the same definition.

Net Area of Apartments in Turkey: What Do You Actually Get?
Knowing an apartment's net area when buying property in Turkey helps you determine whether the home meets your everyday needs. Two apartments may appear similar in terms of the number of rooms and gross area, yet one may offer more interior space because of differences in design, wall thickness, and room layout.
What Is Included in the Net Area of an Apartment in Turkey?
According to the definition of net area in Turkey's Zoning Regulation, the area is calculated between the walls, subject to the specified exclusions. It includes qualifying interior spaces such as bedrooms, living rooms, kitchens, bathrooms, and corridors, depending on the nature of each space.
By contrast, certain elements are excluded from the net area under the regulatory definition. These include columns, some technical and structural spaces, and open areas such as balconies and terraces where the relevant exclusion applies.
It is important to distinguish between the legally defined net area and the area a marketer describes as "usable area." A marketing expression alone does not prove that the measurement complies with the legal definition.
How to Calculate an Apartment's Area in Turkey in Square Meters
You can estimate the area by multiplying the length of each room by its width and adding the results. For example, if the combined areas of the rooms, kitchen, bathroom, and corridor amount to 60 m², this is the estimated total before checking the regulatory exclusions.
The sum of these spaces is 60 square meters, but this alone does not establish that the apartment's legally defined net area is exactly 60 m². All qualifying areas and the applicable measurement method must be verified.
How Can I Find Out the Actual Area of an Apartment in Turkey?
To verify the actual area of an apartment, follow these steps:
- Request the architectural floor plan: It should show the room layout, dimensions, and areas.
- Review the project documents: Compare the area shown in the floor plan with the area stated in the sales offer.
- Check the contract: Make sure the net and gross areas are clearly stated rather than relying on the vague phrase "apartment area."
- Measure the apartment if necessary: If the apartment is completed, you can consult an engineer or specialist to verify its dimensions.
- Compare the promised area with the actual area: If a significant discrepancy appears, request a written explanation before completing the purchase.
The Turkish Ministry of Trade recommends reviewing net and gross areas, the independent-section plan, and the project's general site plan before signing contracts for off-plan residential properties.

Gross Area of Apartments in Turkey and Its Different Types
Gross area does not always refer to the same measurement in every Turkish real estate advertisement. Turkish regulations distinguish between the gross area of an independent section, the total gross area that includes its annexes, and the general gross area, which also includes the section's share of common areas.
This distinction is particularly important when buying a new or off-plan property. An advertisement stating an area of 150 square meters may refer to a different measurement from another advertisement using the same figure.
What Are the Types of Gross Area in Turkish Real Estate?
The following terms are used in Turkish zoning regulations:
- Bağımsız Bölüm Brüt Alanı: The gross area of the independent section, measured according to its external boundaries and subject to specific regulatory exclusions.
- Bağımsız Bölüm Toplam Brüt Alanı: The total gross area of the independent section plus the area of its annexes, if any.
- Bağımsız Bölüm Genel Brüt Alanı: The gross area of the independent section plus its share of the common areas.
Turkey's Zoning Regulation explains these distinctions. Therefore, the three terms should not be treated as interchangeable.
Does an Apartment's Gross Area Include the Balcony, Parking Space, and Elevator?
The answer depends on the type of area being referred to:
- Balcony and terrace: They may be included in the gross area subject to regulatory conditions, but they are not included in the net area if they are open and legally excluded.
- Private parking space: Check whether it is allocated to the apartment and whether its area is calculated separately.
- Storage room or basement: It may be treated as an apartment annex if the documents designate it for that apartment.
- Shared elevator, staircases, and corridors: The apartment's proportional share may be included in the general gross area, rather than being treated in the same way as the gross area of the independent section.
It is therefore not enough for the seller to say that an apartment measures 140 square meters, including the parking space and balcony. You need to know whether this figure represents the apartment alone, the gross area including annexes, or the general gross area.
What Does Satış Brüt Alanı Mean in Turkey?
The term Satış Brüt Alanı refers to the gross sale area, but it does not by itself specify the method used to calculate the area or whether it complies with Turkish regulatory definitions. Therefore, when reviewing a property advertisement, request written clarification covering:
- The apartment's net area.
- The gross area of the independent section.
- The area of annexes, such as parking spaces or storage rooms, listed separately.
- The apartment's share of common areas, if included in the advertised gross figure.
- The area stated in the sales contract and architectural plan.
This step is particularly important for properties sold before construction is completed. The Turkish Ministry of Trade recommends checking plans, areas, and the features promised in the contract before purchasing.

Net Area in Turkish Real Estate Advertisements: How to Avoid Misleading Information
A property advertisement may contain a correct figure but fail to clarify the type of area being described. Understanding the terminology used in Turkish advertisements can help buyers identify discrepancies before paying a deposit.
How to Read an Apartment's Area in a Turkish Advertisement
| Turkish Term | Meaning in English | What Should You Verify? |
| Net Alan | Net area | Does the figure match the architectural plan? |
| Brüt Alan | Gross area | Which definition is used to calculate it? |
| Bağımsız Bölüm Brüt Alanı | Gross area of the independent section | Does the figure include the balcony according to the applicable calculation method? |
| Toplam Brüt Alan | Total gross area including annexes | Are there actual annexes identified in the documents? |
| Genel Brüt Alan | General gross area | Has a share of common areas been added? |
| Satış Brüt Alanı | Gross sale area | What calculation basis does the seller use? |
| Balkon Alanı | Balcony area | Is it listed separately from the interior area? |
| Eklenti Alanı | Annex area | Is the annex allocated to the apartment in the documents? |
How to Compare Two Apartments When Buying in Turkey
When comparing two apartments at the same price, the second may offer more interior space. For example, the first apartment has a gross area of 120 m² and a net area of 95 m², while the second has a gross area of 115 m² and a net area of 100 m². The second therefore provides 5 additional square meters of net area.
If your goal is family accommodation, the net area and room layout may be more important than the gross figure alone. If you are buying for investment, you should also consider location, views, building quality, expected rent, and the price per square meter.
How to Calculate the Price per Square Meter Correctly
The price per square meter is calculated by dividing the apartment's price by its net or gross area. For example, if an apartment costs TRY 6,000,000 and has a net area of 100 m² and a gross area of 125 m², the price per net square meter is TRY 60,000, while the price per gross square meter is TRY 48,000.
Both calculations are mathematically correct, but they measure different things. To compare the interior space available for use, the price per net square meter is more informative, provided that the net area is documented and calculated consistently across the properties being compared.

Steps to Verify an Apartment's Actual Area Before Signing the Purchase Contract
Understanding the difference between net and gross area is not merely a matter of calculation. It is an essential step in verifying property details and comparing marketing information with official documents. This helps you assess the actual space and understand what you are paying for before making a purchase decision.
What Documents Should You Request from the Seller?
Before completing the purchase, make sure to review the following documents:
- Approved architectural plan: To verify the room layout, dimensions, and areas.
- Independent-section plan: To identify the apartment's boundaries and associated annexes.
- Preliminary information form and sales contract: To review the promised areas and compare them with the areas stated in the plans.
- Title deed (Tapu): To verify the property details, independent section, and any registered restrictions or annotations. However, the title deed alone is not always sufficient to establish the apartment's net interior area.
- Documents relating to annexes: Such as a parking space or storage room if they form part of the transaction.
The Turkish Ministry of Trade emphasizes the importance of reviewing the site plan, floor plans, independent-section plan, technical specifications, and both net and gross areas when purchasing off-plan residential properties.
What Should You Do If the Actual Area Differs from the Advertised Area?
If you discover a discrepancy between the area stated by the seller and the area shown in the plans or measured on-site, do not automatically assume that the difference is minor or acceptable. Instead, follow these steps:
- Request a written explanation identifying the reason for the discrepancy and how each area was calculated.
- Consult an independent architect or specialist to review the measurements if necessary.
- Compare the results with the approved plan and contract, not just the advertisement.
- Keep copies of the advertisement, correspondence, contract, plans, and relevant invoices.
If the discrepancy is significant, consult a lawyer specializing in Turkish real estate law to determine the available options under the contract and the circumstances.
Legal rights vary depending on whether the property is completed or under construction, the nature of the contractual obligations, and the extent of the discrepancy. Therefore, you should not assume that a buyer automatically has the right to recover a specific amount or terminate the contract simply because the two area measurements differ.

Frequently Asked Questions About Net and Gross Area When Buying Property in Turkey
Net area (Net Alan) refers to the apartment's usable internal floor area according to the applicable legal definition. Gross area (Brüt Alan) is calculated based on the boundaries of the independent unit, taking into account the walls and elements included or excluded under the regulations. Common gross area, on the other hand, also includes the apartment's allocated share of shared areas.
Open balconies and terraces are not included in the net area under the Turkish zoning regulations, even if they are designated for the apartment's private use. They may be included in the gross area subject to the applicable regulatory conditions. Therefore, buyers should check the architectural plan and the method used to calculate the area.
Request the approved architectural plan and the independent-unit plan, and check both the net and gross areas stated in the sales contract. If the apartment is completed and you notice a discrepancy, consult an engineer or qualified specialist to measure the area and compare it with the approved documents.
Not necessarily. The gross area of an independent unit differs from the common gross area. The apartment's share of common areas is added when calculating the common gross area, whereas this share is not included in the same way when calculating the gross area of the independent unit.
If your goal is to determine how much interior space you will actually use, the net area is the better starting point. However, you should not base your purchase decision on this figure alone. The layout, location, natural lighting, view, construction quality, total price, and legal documents are all factors that affect the property's value.
Conclusion: How to Choose the Right Property Based on Its Actual Area
Understanding net and gross area when buying property in Turkey is essential for making an informed decision, whether you are purchasing for residential use or investment. Comparing Net Alan and Brüt Alan clarifies the difference between interior space and the gross area calculated under the regulations.
Distinguishing between the gross area of an independent section and the general gross area also helps buyers understand the figures in Turkish real estate advertisements and avoid confusing the apartment's own area with its share of common areas.
Before signing the contract, verify the apartment's net area, the property's gross area, the area of any annexes, and the approved architectural plan. Make sure to compare the price per square meter using the same measurement basis across all the properties you are considering.
The most important rule is simple: do not buy an apartment based on the larger figure in the advertisement. Make your decision based on the documented area, the precise method used to calculate it, how well the apartment meets your needs and budget, and a review of the legal documents.
