In no case it shall  be less than the space arrived at by  drawing a quadrant of a circle of 4.5m radius at the edge of the actual road lines leaving the width of pedestrian walks (foot path) and the plot boundaries shall be rounded of by drawing a quadrant of the circle of 2.7m radius at the edge of plot boundaries.
