Raj - What you say is true that a lot of interior design's margin is in furniture. I will not sugar coat it. And many designers may seem to be more interested in that when you bring them in. But I have had several clients call me over the years saying they are building a new home and would like to consult primarily on layout. When you speak to someone is tell them you are not ready to order furnishings or window treatments, but that you would like a contract that focuses on layout, planning, and interior detailing (i.e. doors, trims, floors) - i.e. the bones of the house. What I would suggest is when you call for a designer, you be prepared to pay a good consultation fee. A good rule of thumb is that you can expect to pay between $3-$10 per square foot of your home depending on the area of your country and the expertise/experience of the designer. If you are not averse to paying this type of fee, and communicate to the designer that your interest is in getting the best solutions, not in purchasing furniture at this time, I'm sure you will be able to get the level of service you desire. If someone you talk to doesn't seem thrilled to provide this kind of service, move on to the next person. Don't rely on "fame" or how well known someone is. They may be well known for doing show houses or just because they've been in the field the longest in your area. Not because they're the right fit for you. You could also check the Houzz directory for good designers in your area. The difficulty is that there are often decorators whose expertise and focus is really just on furnishings not so much on construction - and they serve a purpose for their clients. But there are other designers who provide more of a wholistic approach and have more familiarity with building a new home. These are the people you should seek out. Houzz is a fantastic community - and as I said you may get good advice here but there's really no replacement for someone to work with you in person. Sorry for the super long post but I feel passionately about this and I think this advice will best suit your needs.

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.

This layout is not what i would ever suggest to a client for starters the MBR and DR are all wrong , who wants to walkthat far with food from the kitchen the DR is completely closed off of the rest of the space just too many things to correct for me.I really dislike homes built to look great from the outside with no proper function on the inside

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. :)
