Hi Suraj, I suspect people haven't responded yet because your photos don't really show enough context for us to make specific suggestions. Are there pieces of furniture or rugs in your living room that you need to coordinate into your colors and design? Or is it a blank slate, so to speak? Are there colors or design styles you are particularly attracted to? I certainly feel I need more information to give you specific advice about the space. All I see are almost bare walls, what looks like the top of a corner desk and a TV. I'm also not sure about your comment about ledge stone. Could you explain your needs and style preferences further or add photos that show us more of what's in the room?

Depends on the shape, location, type of stone, how you plan to hang it, and what else is going on in the room. Can you post pics?

I wouls get rid of 1/2 the pillows on the sofa too matchy add an area rug that is bright with some other colors to use for accents you have IMO too much brown so I would do blue drapes in the DR take the cloth off the table and add a blue and orange glass bowl for a centerpiece filled with green apples get some pillows in green and orange and a big piece of art work for the wall above the sofa and maybe a mirror on the DR wall and a fabulous light fixture for the DR an arc lamp behind the sofa in the corner so it comes out far enough into the room to light a coffee table.

Pooja this information is not sufficient. Please share your floor plan to understand the layout.
