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?

this looks awfully cold ( color wise) and somewhat commercial - I would use more earthy warm beige stucco and use some wood rather than painting the lap board shown, break down the mass by selecting a mass ( such as the two story massing above carport and introduce some stone veneer for a more earthy look - check out modern house category for some ideas how modern facades are normally treated.

Thank u all so much, though I must clear the confusion on the pic I posted... The actual space as of now has -'no cladding or wood planks' what so ever, it does have the same rectangular shape, the same ceiling pop, with the same electrical points for TV, and a balocny at the opposite end. Which is why, I was seeking your feedbacks. :)
