Hi jaymodh. These panels have different price points, most range between $20-$60 per square foot. Try contacting modulararts via info@modulararts.com | 206 788 4210. I am not sure if they would work with you though(because you are a homeowner, a lot of companies would only work with architects/designers). If that does not work, contact Linda at Studio Glass Works at (608) 836-6500 ( Unites States code is 1). We order those panels through her company. Ask for textured wall panel system. Let me know how it goes :)

the first is close to the true colour of the wall paint. second picture shows the colour as dark but it is not at all that dark.

what are the International wall texture brands available in India?

Ka_kamakshy interior architect , Did you check with your contractor why he thinks it will fall down. May be he hasn't done it earlier or he doesnt want to do it. It is very much feasible to clad the walls with marble/granite/ other finishes.
