What is FAR?

Floor Area Ratio is the allowed habitable space for a property.     

When calculating this ratio, the habitable space is divided by the site size. Non-habitable space such as covered patios, garages and store rooms are excluded. 

For example, if your ground floor is 200m2, including a 40m2 garage and a 60m2 covered patio and your second floor is 200m2 including a 10m2 store room on a 1 000m2 site.

The FAR is calculated as ((200m2 – 40m2 – 60m2) + (200m2 – 10m2)) / 1 000m2 = 0.29.
