THE STANDARD ROOM SIZE & LOCATION IN RESIDENTIAL BUILDING
What are the Standard Room Size & Location in residential buildings? In this article, you come to know about the various standard dimensions of different elements of residential houses.
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 the 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)
- 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 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 stories. FAR is also used in classifying the type of construction on the basis of resistance offered by building against the fire.
