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 .

It is often best to choose the wall paint colors last. These photos (click to enlarge) might give an idea for working with the colors your chose in the bedroom. Substitute modern furniture.

If you want to let in more natural light, I suggest either solar shades or sheer shades. Both let in plenty of natural light without sacrificing privacy. Here are examples of both: http://www.blindsgalore.com/solar-screens http://www.blindsgalore.com/sheer-shades

Hi Deepak, Neighboring noises can be annoying, especially night. I would advise the same, go for u-PVC windows, that will help in maximum noise reduction. As I can see in image, a full-length curtain indicating probable full window or door. You should go for u-PVC window/door for that too. The noise will be reduced to a minimum. -Thanks, -Neelam -Lines and Profile
