if you recommend tiles then what kind of tile or if stone then what type. ?

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

Hello Neetu, Trying to explain the suggestions earlier made with an image. See if the following space makes the space more usable and open. Please see the numbers marked on the attached image. 1- Open up Dressing Area. No need of closing it. 2& 3 Pull out the Porch and increase the room size. 4- Change the direction of toilet, increase the size and include handwash within it. 5 Open Living area will comfortably seat 6-8 people. 6,7 - If your designer agrees this will allow you to increase the room sizes. by 20 odd ft. 8- Close the kitchen door . Change alignment of Kitchen slab and decrease wall/slab size on the other wall 9- Move Pooja Unit to the wall marked. Thanks Amit Cornerstone Designs. Bangalore.
