The concept of setback has been implemented so as
- To improve the air circulation quality around the building and also to help prevent fire from spreading to neighbouring plots
- Especially in the corner plots, FSI plays an important role by increasing the visibility and safety from traffic, providing privacy from the neighbouring building
- These setback spaces also act as a buffer to control the outdoor nuisance from the road.
Setbacks might differ in different regions depending on the size of the plot, the road, one- or multisided plots, etc.
There are a few structures or built elements that can be constructed on a setback, which include
- Sunshade (less than 0.6m)
- Wardrobes above ground floor (less than 0.6m)
- Non-continuous balconies (less than 1.20m)
- Architectural projections (less than 1m)
- Open service veranda to kitchen above ground floor (less than 1.20m)
- Staircase open landing projections without affecting the driveway below (less than 1m)
- Cantilevered portico so long as it does not fall within 1.5m from the street alignment or the site boundary, whichever is closer, are few minimum standards that have to be mandatorily followed as per CMDA.
- This set-back space on the ground floor can also be used for Parking vehicles, landscaping, etc.
