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 .

I think the most important thing for you to do to your bedroom is to make it look interesting. I wouldn't worry about whether the walls are light or dark, as long as things are well lighted, with dimmer controls. I love the bedroom below. If I were copying this bedroom, I'd place mirrors in the framed area above each nightstand. Those white art pieces made with small branches that are above the bed are from Z Gallerie and run about $39 each. Pretty cool!

I select these colours with the help of other houzzer and expert professional advice and discussion. I also got help from colour paint catalogue. Is it looking good or not? Is there any problem with these colours and their combination. Please guide me in this regard.

Thanks @dream design and @cornerstone. this is my living cum dining room..floor plan is attached below i am having a brown tinted mirror wall on the longer side of the dinning area. 1) which color shade to choose for giving it a rich sophisticated look which will go well with the mirror. I have shortlisted Sonnet as advised in previous comment. What about Morning Glory and Pure Ivory. 2) color shade from Asian paints for ceiling 3 ) also will it be a good idea to paint tv unit wall and/or small wall on the dining side with a grey shade or a different colour ( you suggest) 3) I am attaching the picture of work which is going on.
