Hey Sudha ji , I'v a few ideas on the placement , a bed takes 9'x6'3'' so place it on the 15' Wall(you can reduce the width by removing side drawers,then you get 3' extra for bigger wardrobes on both sides) with one wardrobe on each side one for him and one for yourself and a chest of Drawers to keep other stuff handy and two Ottomans or love seat in front of the bed so you have enough space in front of the bed for traffic as well,and on the front wall to the bed place your Wall hung T.V, PLEASE keep the colours light , use white marsh by Asian Paints or Honey dew , here are some pics .

Hello! If you have about 7' of continuous wall space, you could centre a small desk on the wall, then flank it with Ikea Kallax storage shelves. Use their Drona tote bins to corral messy stuff, and leave other cubbies open for the backpack, books, etc. Showing below the 48" wide Josephine desk from World Market - the front drawer can also flip open to come a keyboard shelf. Also comes in other colors. Also, the smallest Kallax shelf in their series (16 1/2" wide). Another possibility, depending on how the room is configured, is to butt the desk up to the foot of the bed. This should allow about 2' of chair space in front of the desk. You then might be able to use a larger Kallax shelving unit. They come in some great colors in the larger sizes - turquoise, pink, etc.

Do you want to work with what you already have? Are you able to purchase new items? Do you have someone who can provide carpentry for built ins? Do you have a budget. Will design just be for sleeping area or seating, desks, closets or clothing storage and bathroom? Are girls there long term or temporary?

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.
