How to calculate Building Coverage Ratio?
BCR is the ratio of total plot to the total area coverd by the building.
Let us assume you have a plot of 400 Square meter. And our building covers 220 Square meter of land to be constructed.
Then, The Formula for Building Coverage Ratio (BCR) will be,
BCR = ( Building Coverage Area/Total Area of Plot) x 100%
i.e BCR = (400/220) x 100% = 55%
Generally, BCR is calculated in percentage. According to different building law of the country. BCR may be different for different types of building. Generally adopted BCR are given below.
- Residential building should not have more than 70% BCR.
- Commercial building should not have more than 60% BCR
- Industrial building should not have more than 55% BCR
