Need more information...........what is the height variation or fall from the elevation at the top of the stair and where the run would end at the lower landing? What is the length of the run in a horizontal measurement? These are all factors in the code compliant design of the stairs.......not just the width.

You really don't have the floor space for a stairway on that plan, even a spiral. If possible, try to squeeze out some space next to the entry door to avoid having it in the middle of the plan. It might not cost a lot of additional money to have the stairway as a bump-out along with the front door.

Hello Krishna, I would suggest to go for a white brick texture on the main wall with earthy shade of brown for the window shade. The side walls can be a offwhite or beige shade Trust this helps you . If it does will appreciate if you can write a good review on my page snsofdesign Thanks Smitha

Hello, I jut saw your comment. thanks for the same. Appreciate your suggestion. Could you please help me to get some construction engineer who can help me to design my ground floor which is about 4 ft underground where the floor and ceiling are already there. The side walls are also there. Only thing is the partition wall to be created to make as a single bedroom house. At present on the east side there is a garage and on the north side a room with toilet. We would like to convert this as a proper single bed house. Since I have a very low budget, can you please suggest how to go about it. Thanks and look forward to your advise.
