Vastu shastra for Staircase, Steps, Spiral steps are called with different names in different places. Rung, shed, stairs , Staircases, steps etc. (There are many other types of staircases like, Iron steps, Steel, Wooden, round shaped, Helical, Spiral, RCC etc) How to arrange steps, this is clearly explained here. Depending on the availability of vacant site in and around a home they can be arranged against entrance or outside. Suppose an internal staircase has to be provided. Then the room in the northeast and northwest should be left out. Then leaving at least 3 inches from the east wall , without touching it, direct steps from north to south should be there. Otherwise alongside or away from the southern wall from to east to west steps can be arranged; or alongside or away the western wall from north to south and above the inter space principle may be followed in respect of the stair case towards north to step from the east to west.
Suppose a linear staircase is designed either inside the house or outside the house. Then it should be from east to west or north to south. Then it may take any direction. Outside the house, if a staircase is provided in eastern southeast, the eastern compound wall should not be touched. It should be from north to south and proceed from there towards north from south after the landing. That will lead to entry into the first floor in an exalted position. It will be through the balcony provided in the eastern northeast part. Then a balcony can be arranged in the north side also. There should be no pillar under the landing. It should be built on a cantilever beam. Observe the following design.
In this picture the steps came to Agneya (Southeast) place towards east side, this type of constructing steps is auspicious, but here you should not forget the thing that you have to balance this Eshan (Northeast) missing, because steps are extending the East agneya, it means the Eshan corner is to be less, so we have to made some adjustment of to do like varrandah towards Eshan side at East direction. How to set up the balcony and the model of it, for this please observe the below picture.
Here please observe the Balcony is occupied to balancing the Loss of Eshan due to steps placed at Agneya Corner towards East side.
If stair case has to be built in the west in south west the steps should be from north to south. There after the landing turning should be arranged from south to north and from the north west balcony one should enter the first floor exalted place. In this way when staircase is built in the west there will be a balcony in the west. So one balcony should be built in the east. In North too there should be a balcony. See the design.
