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 :)

@ Divya Sreedar. You will have to contact all of the ceramic boutiques that deal with imported tiles in Chennai. Attached below is a photo from AMSET ONE store in trivandrum with the subway tiles on display as I have seen. It takes 3 weeks to arrive from order date. If you like us to deal with the purchase please contact us or you could call them directly to find out.

and yeah.. I have read of fibre cement board, tiles, texture paint and plaster from Balaji texture. Any other cost effective ones

Dear Mr. Manjunath, It would be really better if you collect quotes from both online/offline professionals. When a turnkey project (Design + Execute) is assigned, overall costs remain low and would be better negotiable with the construction firm. For design only, it depends on the intricacy of work and the BUA of house. Normally, a site visit and a 2D/3D layout without approval assistance would come in between 2.50- 30 rupees per sqft of BUA depending on the firm's category.
