Its a really lovely room! what a great place for kids to share. I like kids sharing rooms. I think you need another colour to tie it together. I would suggest a blue tone.... teal, navy blue, duck egg blue. to tie it together. Its a little to pale and looks sparse, but actually isn't. I would leave everything exactly as is, BUT, paint the back wall behind the bed teal and find a simple navy blue wall decal that is fun and kid- like maybe one with a sillouette of a boy and girl playing. I would paint the wall behind the sofa duck egg blue. Then I think it would suit both kids more and look more kid friendly. the blues will balance the pink and cream, but because you have a pale carpet i don't think it will look too dark. don't worry about making it totally kid like, its a room they will grow with, not a kindergarten, and it also needs to peaceful and restful for sleeping. besides with their art on the walls and bright toys everywhere it soon looks bright and kid like. Good luck!

Pictures are needed

You can opt to have an elevated bed with a chest of drawers under it for more storage and the elevated area could be in a corner so as to provide free space for study area. If you'd like to work with this idea I would be able to design the furniture as per your needs and space available.

Vinay, Since you have hired a professional, not sure how much of below will make any sense. This is a tall-boi room and the windows and doors height add to it. You have quite a good exterior view with surrounding greenery but the messy grills have kind of killed that view. You may have to always use sheer to hide them and coupled with earthen colored curtains. Plain bland white walls is another thing you may want to reconsider. Without going into too much details, a clean contemporary look for this place would be best suited. The ceiling lighting doesn't seem sufficient for a 14*15 room and I feel there is too much of wood on the ceilings even in the other parts of the house. As of now it looks like a transit place and glad to see this being made a permanent home. Will be eager to see the end results. Thanks Nitin Cornerstone Designs, Bangalore.
