Section 107(3) in West Bengal Municipal (Building) Rules, 2007
(3)For the Corner plots, the width of wider side space will be reduced to counterbalance, the difficulty of planning of the building due to rounding off the frontage but the clear gap with its adjacent building shall never be less than 2.5 metres (8'-2"). The side spaces of the corner plots will also be suitably adjusted where provision for paved passage, open ground, play-ground, will allow for such adjustment. The maximum covered area and F.A.R. will however remain the same as in other plots.
