Some kind of teak wood would be best. IPE is what this looks like. Please purchase responsibility as it is harvested by clear cutting in some areas. FSC is best.

Farooq, First one is a glass finish Subway tile. It looks good but many people back out due to budget issues as it is relatively costlier. Second image is of a brick cladding wall paper. However, similar looking ceramic tiles, mud tiles are also available locally. IMHO, red brick sand tile gives a more natural effect.What suits better would depend on the overall design of the house. Thanks, Nitin Cornerstone Designs, Bangalore.

As it's being used in External area few materials that can give similar look & feel 1 ) Wood finish ACP panel 2)Wooden logs with PU coating ( Expensive) 3) Wooden coated Allumnium pipe sections 4) wood finish All weather Shera boards

It will cost you 25/- per sft for tile laying in a metro city and if you go for italian marble it will cost around 115 per sft including polishing after laying.
