1. Area Limitation

The limitation of the area and height of the buildings of different types of construction and occupancy is achieved by satisfying the floor area ratio (FAR). FAR is taking into account the following aspects,

Occupancy class
Type of construction
The width of the street fronting the building and the traffic load
The density & Locality where the building is proposed and.
Parking facilities
Fire Resistant Materials Used in Construction
Water supply and drainage facilities.

Floor Area Ratio(FAR) = (Total cover area of all floors/ Plot area)

The floor area ratio for residential buildings is ranging from 1.0 to 2.0 depending on the type ‘of construction. It restricts the height of the building and the number of stories provided.

For example, if a plot measures 15 m x 20 m and building bye-laws stipulate permissible FAR as 2.00, then the maximum built-up area which can be put on the plot is 600 m2.

If the area covered on the ground floor is 150 m², the total number of floors that can be constructed is (600 / 150) = 4

Thus, with these bye-laws, the height of the building cannot be more than 4 stories. FAR is also used in classifying the type of construction on the basis of resistance offered by the building against the fire

A square footage calculator is a tool used to measure the area of a given space, such as a room or a piece of land, in square feet. It is commonly used in real estate, construction, and home renovation projects.

2. Height of the Building

The height and number of stories for a building are related to FAR and the provisions of open spaces are already explained earlier. Where the building height is not covered by FAR, the maximum height should be limited to the width of the street as follows.

(i) The maximum height of the building shall not exceed 2 times the width of the road abutting plus the front open space.

(ii) If a building abuts two or more streets of different widths, the building shall be deemed to face the street that has the greater width and the building height shall be regulated by the width of that street.

it may be continued to this height to a depth of 24 m along the narrower street subject to the conformity of open spaces.

(iii) In the vicinity of aerodromes, the maximum height is fixed in consultation with civil aviation authorities.

Appurtenances like a water tank on the roof, ventilating and air conditioning appliances, lift room, chimneys, and parapet walls not exceeding 1.2 m in height are not included in the height of the building.
