yes, but need to understand it well with ur local fabricator how n wht design he gonna implement as it's purpose is very imp and it must be sturdy while in use.

plz suggest me options for material for staircase as well railing and side wall elevation according. thanks in advance.

MK, Covering with fixed frosted glass in aluminium partition up to the height of railing and louvers till ceiling should be enough to address your requirement. It will be trade-off between privacy and air circulation in most of the methods. Pigeon net also provides a good degree of privacy but this appears to a first floor apartment it may not be that usable for privacy. Thanks, Nitin Cornerstone Designs, Bangalore.

Hi Ashish, You can opt for any of the following options - 1] Frame the L- shaped junction of the wall and beam/ceiling with a wooden frame similar to your handrail and fix glass into it as shown in the image below. 2] Alternatively, you can go for other options like a jali or rafters to secure the opening and complete the look. Like this - Doing this would provide an enclosure to the staircase and give you some storage space below the landing as shown below. Conceal the space with a veneer finished door and a handle and you are good to go. You may store hardware items, gas cylinder, gardening equipment etc. or convert it into a wine cellar if you like. All the best! Regards, RnD Atelier Nagpur
