The floor area ratio(FAR) is the ratio of a building’s total floor area (gross floor area) to the size of the piece of land upon which it is built. It is often used as one of the regulations in city planning along with the building-to-land ratio. The terms can also refer to limits imposed on such a ratio through zoning.

Written as a formula, FAR = gross floor (building) area ÷ area of the plot.

The maximum ground coverage (MGC) depends on the land size and the width of the road at the entrance. The front road width also affects the FAR values. In short, the square feet/ square meter multiplied with FAR value will result in the maximum construction area of a building. As a rule of thumb, FAR is 3.75 for a 5 Katha plot with a 25′ wide front road. Hence, the maximum ground coverage (MGC) will be 62.50% which would be 13,837 sft as the total construction area with verandahs.

The number of parking spaces depends on land size, land shape, building height, basement provision, car lift, park lift, etc. This is determined on a case-by-case basis. As an example, a 5 Katha plot may have 8-9 car parking spots, depending on various factors.

The basement floor construction is generally expensive and unless constructed with care, there can be water leakage and dampness. For smaller plots of land below 8 Katha, basements are not generally feasible. However, for larger plots of land requiring a large number of parking spots, basements become a necessity.

Space sharing refers to the use of space in a building by the Landowner and the Developer. In a joint venture development, space sharing depends on a mutual understanding between the Developer and the Landowner. There is no fixed formula for this and it depends on the land value, selling price of the property, the number of apartment units, and the agreed signing money.

Floor distribution is done through mutual understanding between Landowner and Developer. Both Landowners and Developers choose the floors as per the merit or value of the property.

The size of the apartment is the net floor area of the apartment plus the common areas as specified in the Real Estate Management Act 2010.

As per the Real Estate Management Act 2010, spaces such as lift-lobby, staircase room, lift machine room, generator room, sub-station room, caretaker’s room, guard room, and other common facilities like gym space, prayer room, library room, guest waiting area, reception area, etc. are considered as common space.

In Dhaka, RAJUK and Cantonment board is the final authority for approval of plans and in Chattogram, it is CDA. Plan approval depends on various factors such as building height, whether it is a regular or special project, number of apartments, road-width, the permission of concerned authorities (Civil aviation, traffic, DMP, environment, etc.), conditions of the township planning department, whether it is a leasehold property or freehold property, land status, etc.
