How this is calculated
Max buildable area = Plot area × FAR

About this calculator

The FAR (Floor Area Ratio) calculator multiplies a plot's area by the FAR permitted by local development regulations to estimate the maximum total floor area that can legally be built on it.

Worked example

2,400 sqft plot with FAR 1.5

Result: Max buildable area = 3,600 sqft
