Hi Adrain, Again thanks for showing interest in my post. I have highlighted my plot on a piece of paper. There are two parts marked as L and R. As I told u earlier i am making on half of the plot size available to me. Either I can make on L or I can make it on R. There are no such restrictions on material to be used but in India we don't used wood to make outer walls. General practice here is to use bricks and cement. I am adding to photographs one is a piece of paper highlighting my part of plot and the other is the google map pic. I cuing highlight in tht but I have marked it with red my side of plot. If u can compare both the pics u might be able to figure out the whole idea of the place. As far as the servant room is concerned it is a small room with kitchen and sedate bathroom attacked to the room. It's generally very small and have no access to the main house. To give u an example the servant room may be of the size 10 feet by 15 feet which includes a small kitchen and bathroom including the room too. Shaleen

Since the lot you describe is smaller than my open living area, I would suggest looking at some of the "shotgun" house plans around New Orleans,LA. I think you can build up and back and get an interesting home with a loft for space. It can be done, A porch with an entry to a narrow hall at the back might work best for you. Will you plan a courtyard (closed)? or what? What part of the country are you in? What are your local codes?

There are actual rules about staircases as to riser height etc so best to get an architect involved in the process this will take up a lot of sq. footage too.In many places a spiral staircase is not allowed only if the elevator can hold a stretcher

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.
