A PLANNING TOOL
Make room for
the possibilities.
A simple floor area calculator to help you understand the relationship between plot size and a supplied FAR ratio.
TOTAL FLOOR AREA AT THIS RATIO
200 m² plot × 2 FAR
How it works
Plot area × FAR ratio = total floor area. This is the aggregate area across floors under the ratio you enter.
This is an arithmetic planning aid, not an approval or a statement of permitted development. Setbacks, height limits, ground coverage, exemptions and local rules also affect what can be built.
