What is Setback in housing? Need for Setback and CMDA Norms

In Chennai, what should the setback be for houses?

The setback concept has been implemented in order to increase the quality of air circulation around the building and to aid in the prevention of fire spreading to adjacent plots,

FSI is especially important in corner plots because it improves visibility and traffic safety while also providing privacy from the nearby building.

These setback zones also serve as a buffer between the road and the outside world.

Setbacks may vary by area, based on the size of the plot, proximity to a road, and whether the plot is single or multisided.

On a setback, just a few structures or built features can be created, including

Sunshade (less than 0.6m), above-ground-floor wardrobes (less than 0.6m), non-continuous balconies (less than 1.20m), architectural projections (less than 1m), open service veranda to the kitchen (above ground-floor) (less than 1.20m), we are the best builders in Chennai for individual house
