It doesn't look like your photos and floor plan attached, can you try again? Is this an open concept home?

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.

Hello Mr Ranga Nathan Maintain a minimum width of staircase as 3ft, the space in between the flights can be reduced. If possible shift the pooja room toward the partition wall of the kitchen and living. Make a big window for good light and ventilation in the place of the existing pooja room. In the first floor remove 1 toilet and make the bedroom big. For the other bedroom Reduce the size of the balcony and increase the size of the bedroom. Use light colors for furniture and avoid heavy furniture and dark colors. Keep wall colors and curtain colors neutral . Add more mirrors.
