Hi, If you want to be a good civil engineer, you
must have knowledge to read the drawings. A good drawing conveys all the
details of structure. Before Implementing the drawing on the site, knowing all the detailed which is mentioned in the drawing is quite crucial.
By Knowing all the parameters, this article explained
about the different types of areas which is available in the floor plan drawing
such as plot area, circulatory area, setback area, Built up area, carpet area
,ground coverage, open area.
Before that I'll recommend you to read "How to calculate the number of Brick in 1 cft Wall".

By reading this articles all the confusion will be cleared.
1. Plot Area:
The area
which is enclosed or bounded by the wall or boundary wall is called plot area.
In simple Language, plot area is defined as the land which owner (person)
purchase for infrastructure development such buildings, factory etc.
2. Built Up Area/ Plinth Area:
Built up
area or plinth area is the total building area. Built up area includes carpet
area, thickness of wall and balcony.
Built Up area Calculation
Built up area is calculated from the thickness of
wall and carpet area.
Built up
area = carpet area +balcony+ thickness of wall
Note: Built up area is 10% more than carpet area.
To know more details about built up area. I will
recommend you to read " Details of Plinth area"
3. Carpet Area:
The area
which does not include the wall thickness, circulatory area , washroom area ,
Kitchen area, Pantry area etc. In simple, carpet area is the in which carpet is
laid. It is also called useable area.
Carpet
area = Floor Area - (wall thickness + washroom area + kitchen area + pantry
area etc.)
4. Super Built up area:
Super Built up area is the total built up area plus common anilities buildings such as
Ø Security area
Ø Corridor area
Ø Lift area
Ø Parking area
Ø Garden area
Ø Swimming area
Ø Carpet area
Note: Super Built up Area is 30 to 45% more than carpet area.
If you still have confusion then follow the below image. I hope all your doubts will cleared
5. Setback Area:
Set back area is the excludes the built up area from plot area. In simple the empty space which is around the building area.
Setback area = Plot area - built up area
6. Circulatory Area:
This Circulatory area is used for walking or movement of persons such circulatory area are staircase , corridor, porch ,lift etc.
Note: Circulatory area covers 25 % area of plinth area.
7. Floor Area:
It is the
space in which building occupies.It Covers 15-20% of total Floor area.
8. Total Built Up area:
Total
Built up area means covers all the floor of the buildings.
9. Floor area Ratio:
Floor
area ration is the ratio of total covered area of all the floors divided by
plot area and multiplied with 100.
Floor Area
ratio = (total covered area
of all the floor / plot area) x 100.
10. Open Area:
Open area is the area where ground
coverage is subtracted from plot area. Ground coverage is area where road area,
paved areas, landscapes area etc. is subtracted from plot area. In simple,
Open area= Plot area – Ground Coverage
I hope you have gained information regarding plot area, setback area, open
area, floor area ratio etc. If you like this articles please share with others.
