# The Standard Room Size & Location in residential building

What are the Standard Room Size & Location in residential building. In this article you come to now about various standard dimension of different element of residential house.

#### Area limitations:

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

• Occupancy class
• Type of construction
• Width of street fronting the building and the traffic load
• The density & Locality where the building is proposed and.
• Parking facilities
• Local fire fighting facilities
• Water supply and drainage facilities.

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

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 number of storeys provided. For example, if a plot measures 15 m x 20 m and building bye-laws stipulates 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 at 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 storeys. FAR is also used in classifying the type of construction on the basis of resistance offered by building against the fire

#### Height of the building:

The height and number of storey 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 building shall not exceed 2 times the width of road abutting plus the front open space.

(ii) If a building abuts on two or more streets of different widths, the building shall be deemed to face upon the street that has the greater width and the building height shall be regulated by the width of that street and may be continued to this height to a depth of 24 m along the narrower street subject to conformity of open spaces.
