How to Calculate Plinth Area of a Building?
Step 1: Consider a beautiful two store building with the ground floor net plinth area of 92.10 Sq.m. Its net plinth area of first floor is 90.30 sq.m.
Given values here was
Net plinth area of ground floor - 92.10 Sq.m
Net plinth area of first floor - 90.30 sq.m
Net Plinth Area Step1
Step 2: Add all the plinth area specified to get the net plinth area.
Net plinth area = 92.10 + 90.30 sq.m
= 182.40sq.m
Net Plinth Area Step2
Note the following while calculating the plinth area.
→ Not includes area open to sky
