The only wall I would possibly treat differently is Wall B because it's large and there aren't any windows or doors on it. It could have a fairly bold colour on it and the rest of the walls could be much lighter, even a white. That will draw all the emphasis in the space onto Wall B which is probably where you will anchor your sofa arrangement.

Yes Maam, It will be a good idea to have a light on the headrest wall. And as a respected member commented above it is still better to have two on either side of bed to work as reading lights. Thanks Amit CORNERSTONE DESIGNS Bangalore

Surbhi, The width of the room is not mentioned here but from the scale it looks like it is ~8 ft. Effective living area would be close to 90-100 sqft . Grey and darker blue may not a be a suitable palette for this area. However, the tiling is already done. You may want to go for lighter shades for the remaining areas like wall paint (try 8260 Asian paints) and maybe brighter contrasts for sofa and curtains. Bright pastel yellow or beige may be a good combination for upholstery. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore

I feel the room will look even smaller if we went with option B because of the heavy furniture. Do you think the wardrobe wouldn't look pleasing with option A? Also, I can get the whole wall to decorate in option A.
