To attain the right property in Dubai is not a cake walk, as it seems to many. One of the basic things that property buyers must do, non-negotiable, is to gather all the necessary information for real estate hunting in Dubai. The idea is not to get a profitable real estate but to get it at the right price, considering the location and the space that it offers. If you are informed enough, it will eliminate the risk of getting conned and of paying more for less. One such distinction buyers in Dubai should be aware of is between BUA and GFA. Such an important consideration often gets overlooked by many and eventually ends up hampering the investment. In this blog, you will get a clear breakdown of BUA and GFA, their differences, and their influence on the Dubai Market.
BUA, Built-up Area, is the total constructed area of the property. It consists of the total constructed footprints of the property. When you check out real estate advertisements in Dubai, you will see that the area is measured in BUA, which makes the property and the area appear larger, wider, and more spacious. If the property is said to be 6000 sq. ft., that represents the total area the builder used to create the property, and in reality, it would not be the total area the buyer actually uses as livable space. In the Dubai Real Estate Market, BUA includes the internal living space of the property, wall thickness, staircase area, corridors, covered balconies and terraces, and roofed extension areas such as the porch and garage.
To know the area of the livable space offered on the property, GFA, or Gross Floor Area, is a more precise term. It is the total area of the walls and other structures, excluding non-livable spaces such as balconies, open terraces, gardens, yards, parking spaces, and roofed outdoor spaces. GFA is the preferred term used by the Dubai Land Department and the Dubai Municipality when approving buildings. Gross Floor Area is calculated as the summation of all the enclosed spaces between the outdoor walls. It includes bedrooms, living rooms, kitchens, bathrooms, lobbies, lift shafts, internal walls, and columns. Moreover, it is a compliance figure that is affected by the zoning rules and the FAR (floor area ratio). There is a limit on developers' GFA for the properties under construction.
For the longest time, buyers have used BUA (Built-Up Area) and GFA (Gross Floor Area) interchangeably, but there is a huge distinction between the two that you must be aware of before entering the Dubai Real Estate Market. Even though both of them refer to the area included in the property, you still need to understand the basics to get pro at the game. A clear distinction between the two will help you gain a better understanding. Take a look at the detailed tabular form of differentiation between BUA and GFA that is provided below:
| Aspects | Built-Up Area (BUA) | Gross Floor Area (GFA) |
|---|---|---|
| Definition | BUA is the complete built-in space, external and internal, of the property | GFA refers only to the property's internal space, excluding outdoor areas. |
|
External Areas |
Includes all the usable and non-usable spaces, such as balconies and terraces. | Excludes balconies, terraces, and roofed-over outdoor spaces. |
| Purpose | Used for marketing and sales purposes mainly | To get the plan ready for approval and compliance purposes |
| Focus | On the overall built space of the property | On the livable and usable internal floor space of the property |
| Buyer Impact | Shows the complete size of the property, but it is not always preferred | The main factor in figuring out what has been officially approved |
| Used By | Developers, Agents, and Sales Listings | Dubai Land Department, Municipality, and Regulators |
When it comes to property, every square foot counts and can drastically alter the price. In the same way, the measurement plays an important role in affecting the real estate market and its prices. Choosing BUA or GFA for measurements should be done by factoring in the influential points, such as those provided below:
To protect buyers from false claims and depositions, the Dubai Land Development and RERA have strict guidelines that must be followed. In case of any misjudgment of the property or false information, you, as a buyer, reserve the right to report it immediately. The measurements of the property need rightful approval, so refer to the legal implications of BUA and GFA in the Dubai Real Estate Market, as written below:

If you want to win over an existing market, you should be equipped with the right, up-to-date knowledge, such as BUA and GFA.
