Rajesh--I would consult with a designer/architect in your part of the world to correct the reiling deficiency. I cannot speak to building codes in what I am guessing is the far east, but your local architect can. Attachment of the railing, to the floor and to the stairs, in terms of rigidity and support are important, as the rail will slope by the steps, and need to transition to a straight rail at the landing, and terminate into the white wall at the landing. Also, the architect can verify that the steps meet codes in terms of rise and run and the gaps btw. the steps, which would not pass code here in the U.S. I cannot see the while inside wall as you ascend the stair, so all I can suggest is installing a nice piece of art, possibly a triptych, of something culturally fitting for your part of the world. I wish you well in your design pursuits.

OSB board will do the trick. You need another photo for us to offer a species and finish. Natural finish (clear coat...water based polyurethane finish...NO oil modified) in a low gloss or satin finish on white oak with FLOOD LIGHTS will offer the same "look" as the poor photo. Beyond that, you will need a better photo.

you can go for wooden style steps available in full step size. different companies manufacture such tiles with various range of colours and texture as suitable to you.

Hi Harsha, This could be one of two things; a Matte Painted Door in Duco Finish (gives the best results) or a matte polished veneer. In case you're looking for a solid door without the wooden grain, then you should go for Duco Paint with a matte finish. Using veneer will give you wooden grains on the door and it can also be polished to a matte finish. This is the matte Duco finish which you can choose in wooden colours and this is what a matte polished Veneer will look like. Again, there are a lot of options to choose from so you can pick the veneer sheets that have few grains. I hope this helps, In case you need more assistance designing your home, please do get in touch with us! Best CUBSpaces Team Miloni 9921364291
