Turning Stairs

Bifurcated Stairs

This type of stair is commonly used in public buildings at their entrance hall. The stair has a wider flight at the bottom, which bifurcates into two narrower flights, one turning to the left and the other to the right, at the landing. It may be either of newel type with a newel post as shown in figure 9 below left side or of geometrical type, as shown in the right portion of the figure with continuous stringer and hand rails.
