FAR Calculation in BD

What is the Floor Area Ratio (FAR)?

The quotient of the ratio of the combined covered area (plinth area) of all floors, except for areas specifically exempt under these regulations, to the total area of the plot.

Maximum Ground Coverage:

  • The maximum allowable ground coverage both under the canopy and in the building should not exceed 35% of the total site area.
  • The area of the canopy shall not be more than 25% of the total area of the site.
  • In the case of the main road provided without a service road or marginal access, its minimum width must be 40'
  • Siting of Stations on road curves or bends is a safety hazard and should be avoided.
  • The minimum distance of the property line of the Filling Station from the Central line of the road must not be less than 15.00 meters.

Maximum Ground Coverage for RAJUK:

As of my last knowledge update in January 2022, RAJUK stands for the Rajdhani Unnayan Kartripakkha, which is the Capital Development Authority of Bangladesh. It is responsible for planning and development in the capital city, Dhaka.

If you are inquiring about the Maximum Ground Coverage (MGC) regulations or guidelines set by RAJUK for construction or development projects in Dhaka, it's important to note that urban planning regulations can change, and specific details may be subject to updates or revisions.

To obtain the most accurate and current information on Maximum Ground Coverage regulations set by RAJUK, I recommend checking the official website of RAJUK, contacting their offices directly, or consulting the latest urban planning and development regulations applicable to Dhaka.

Regulations regarding Maximum Ground Coverage typically specify the maximum percentage of a plot of land that can be covered by buildings and other structures. These regulations are designed to ensure proper urban planning, control the density of development, and address environmental concerns.

If there have been updates or changes to the regulations since my last knowledge update in January 2022, it's crucial to refer to the latest official documents or get in touch with the relevant authorities for the most accurate and up-to-date information.

FAR and MGC for Residential Building

Floor Area Ratio Calculation:

The formula of FAR=  Total area of Floor / Area of Land (After deduction space for the road)

For Example:

Total Land = 2480.00 sft.  =  3.44 Katha.
Deduction of Road = 170.00 sft. To achieve road up to 20 feet.

Area of Land for FAR = 2310.00 sft.

FAR = 3.50

Total Floor Area = 2310*3.50 = 8085.00 sft.

Maximum Space per Floor = 1480.00 sft. From MGC Chart.
Maximum Ground Coverage, 62.50% = 1443.75 SFT

No. of story =  Total Flor Area / MGC = 8085 / 1443.75 = 5.60

Say = 6 Nos.
