Vikas, you need to stop typing, and pay attention to our advice! You need an architect. If it is a Western architect you're looking for, then search Houzz "Find Local Pros". Perhaps you could contact a Houzzer named Dytecture - here's his Houzz page: http://www.houzz.com/user/dytecture That is really all we can do to help you.

Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.

Yup, in this case it is possible. But: - - having a proper walk in closet is hard - guest toilet will have to serve as common for living area. - average bedroom size would be around 12'X12'. - If there is staircase it will also take around 60-70 sqft area at least. - Please Note- Around 20-25% of total built up area is just wall area. So like if your house built up area is 1000sqft then the Carpet Area( the area which you will be able to see and use) is around 800sqft. Also, it depends on your lifestyle also, the way you live as it is a very subjective thing. For some people 12'x12' bedroom size is more than enough while some prefer having a 20'X16' bedroom with 10'x8' walk-in closet. It would be better if you could provide layout of the land and other information, there are many other factors that need to be consider for any house design. :)

Best to consult an architect as I have said. Plot is a bit small to fit all your requirements in a single floor.
