One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

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.

go to a lighting show room, take pictures of the space and any ideas you have. They are best suited to help you. also have a budget. the how to part is nice but most consumers have no idea that the pendants above are probably 300.00 each. Budget for lighting! take advantage of the pro's in the lighting world, its all we do!

Personally, I would also steer clear of pink. The latest Disney Princesses have been all about the blue, green etc etc. (and I rather like the yellow!) One of the most cost effective solutions is to make a virtue of the existing colour scheme by getting some woodland decals and a couple of small fairies (think: Sleeping Beauty in the woods) for the walls and wardrobe - easy to place and reposition, and easy to remove if you want to change the theme at a later date. See if you can find a big decal that looks like a picture frame, too, and put that on the mirror in the wash area (think: magic mirror!) Some sort of drapery, above the bed is always good. If you're concerned about installing a full corona on the ceiling, you can mount a curtain rail above the bed (don't forget to buy one with crystal sparkly finials!) and hang a set of long voile curtains for a similar effect! I would then advocate sparkly crystal curtain tie backs - they're cheap, cheerful and can be swapped out when the colour begins to bore. Finally, swap out all the drawer pulls and knobs with something glam and crystal-ly in style. Assuming your daughter is quite young, I would say err on the side of shiny bling, and she'll love them! All of these options are pretty simple to do, not too expensive and easy to reverse or change as she grows up!
