Hello Ramakrishna M, This question sounds more for a structural engineer. Also you will need to check if it is legal to do it in your house in the first place especially if you are planning to make an RCC staircase. An Interior designer can help to beautify your space and provide advice on the planning at the max. I could not answer your question directly but hope it puts you in a better direction.

Hi, There are a number of ways in which the area under a staircase can be utilized. In case of a cramped house or space restrictions, this space can be used for providing storage, services or even a powder room as elaborated below : In case there are no space constraints and all the other areas are taken care of, the space below the stairs can be used for add ons such as a library, study, cellar or a minibar. In case there are any dogs in the house, this area serves as a spacious and compact kennel too : Apart from this, if the space is to be treated solely considering aesthetics, it can be livened up using a bit of indoor landscaping, sculptures and water body : Hope these ideas help. Do let us know what you decided to choose. All the best! Regards, RnD Atelier Nagpur

sararahim123 What constitutes an adequate illumination level varies from person to person. What exactly do you require illuminated? If its simply ambient light you would have tiny lights as shown that throw light on the stairs itself. If a bit more is required you could consider adding a railing with a light under. If general illumination is what you are going after, but in a muted way, would suggest wall scones that throw light upwards onto the ceiling, diffusing the light.

Instead of iron grill and glass behind it, you can use FRP grill and glass. You will get a much better design and look in FRP compared to conventional iron grill. We did FRP for one of our project and below is the pic. Please do contact us if you need help with this and other interiors.
