# How to design & calculate a L shaped staircase

Construction Software

In this construction video tutorial, you will be trained to calculate the steps of an L shaped staircase. In L shaped staircase there are one landing and two flights.

You will learn how many steps should be in first flight and after landing how many steps should be in second flight.

The L shaped stair is a deviation of the straight stair that contains a bend in some part of the stair. This bend is normally obtained with the inclusion of a landing at the bend transition point. The bend is often 90 degrees, however it is now always necessary. If the landing is adjacent to the top or bottom of the stairs it is sometimes called as a long L stair.

L shaped is very effective when there is not sufficient space for a straight staircase. Besides, if there are obstructions, walls or space limitations, the L-shaped staircase is useful.

In order to design the "L" shaped staircase, the size and height of the landing should be defined initially. The landing should be built up prior to setting up of any stringers.

In these cases the dimensions of the risers, treads etc. are obtained with the position of the landing.

The landing should not be under the width of the staircase in both directions along with the tread depth in the direction of staircase form the upper floor to the landing.

If the width of the staircase is 36″and it is taken as the minimum dimension of the stair landing. With these information, it is possible to find out the total run of the upper staircase - the staircase running from the upper floor to the landing.

To learn the detail calculation method, go through the following video tutorial.
