cool --but you can see the entire floor has been raised--do you have the ceiling height? a closet 'step up' would be less of a structural commitment, OR a buildup under builtin furniture--like bookcases flanking a fireplace, also some great ideas on HOUZZ i'd never have thought of. sorry i'm not tech-ie enough to paste the site:) of course if you go 'structural' --all walls and ceilings are fair game as well. remember that ease of access [or lack thereof] can affect stealth mode greatly--as in your pic: every time you step onto the 'box' in your pic you would hear a 'different' sound.

For the living room, the focus should be the balcony area. So flipping the couch to face the wall and not the dining table will help. Kind of like this pic. Even if you already have the sectional that is in the diagram, you should be able to flip it. In fact a sectional would probably work better than the couch in this pic. I also really don't like the style of this pic, but it showed what I meant, For the girls' room: No matter which bedroom you choose, you should maximize floor space so that they have the biggest play space possible in their room (as they get older you can add desks for school work and such). To get this space, I would give them bunk beds. This configuration gives them an open feel and more storage, essential for girls. You posted two different kitchen designs. This makes it hard to give you advice. I agree with other posts that your sink should be away from the wall. This allows you to have stuff to the left of you (drying dishes in my house), while you wash vegetables on the right of the sink. You need the same space on both sides of the stove, also. At least 24 inches on both sides is good. 36 is better, though. The first design has a nice little countertop space that adds a place for your daughters a space to sit a watch/ talk to you while you're in the kitchen. When they added this to the first design, you lost cabinets on the other wall. This is bad, as the space is already storage limited. Try making the rounded countertop bump out into the living space more. If you play with the shape, you could make it work without losing the cabinets on the other side. It doesn't have to be rectangular or a perfect circle. You can see how this one isn't confined to the floor plan of the kitchen. I think this is what you would need to do to make it the most functional.

Ankur, There is no point leaving a dead space. Please check with builder if you can shift the french window by a feet out. Rather use this standing space in the interiors and when you need you can open this window. Many builders are now providing this feature as a USP calling it a BALDOW.. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore.

Thank You for your response.. While am still going through the various probabilities of what could be, my idea of the 2 part multipurpose living room would be a planted vertical wall, along a cream/beige stone wall 3D panel to compliment and contrast with bright furniture, grey small sofa with pastel or bold yellow, and accent colors like green and blue in gem tones...carpet/rug, sofa throw pillows, side table...Maybe, a bright yellow Lounge Chair and finish with floor lamps and Lighting to accentuate the same. That said, I do prefer that material used is Eco Friendly as much as possible. The 2nd part of the living room would be eclectic design....neutral small sofa, cream 3D Panel...maybe a turquoise rug. In short, a small boho living space. In terms of budget...While, I do have an idea of the market, I'll like to hear you out. Yes, am open to hiring from outside my locality.
