• The buildings should create better environment.

• The buildings should be located in healthy surroundings and should

have an aesthetic appearance.

FAR – Floor Area Ratio

“Floor Area Ratio (FAR)”- The ratio of the combined covered area (plinth area) of all floors to the total area of plot.


Building height

The building height is the vertical distance from the

average elevation of the proposed finished grade along

the wall of a building or structure to the highest point of

the roof, for flat roofs, or to the mean height between

eaves and ridge, for gable, hip, and gambrel roofs.


Set-back Line /Building line

A line usually parallel to the plot boundaries or center line of a road and laid down in each case by the Authority or as per recommendations of Master/Zonal Plan, beyond which nothing can be constructed towards the plot boundaries excepting with the permission of the Authority.

• Architecture

• Civil Engineering

• Electrical Engineering

• Air-conditioning

• Fire-fighting and administration etc.
