thank you for the options people... i was trying to think a bit of a contrast flooring .... slightly more browner ... ?? What say all of you ? also need the floor to have some texturing dont like absolutely smooth wood will make it feel like paper...

Need photos. There a many different colors of wood!

OSB board will do the trick. You need another photo for us to offer a species and finish. Natural finish (clear coat...water based polyurethane finish...NO oil modified) in a low gloss or satin finish on white oak with FLOOD LIGHTS will offer the same "look" as the poor photo. Beyond that, you will need a better photo.

One Follow-up question.. Is there any strength issue with 20mm Granite slab over 40mm Granite.. Are the 20mm granite slab prone to chipping or crack on normal usage.. Usage would be like, chopping vegetables, keeping hot vessels,.. The normal usage what happens in normal indian kitchen.. I just want to be sure that I decide based on experts judgement (like you), as people are just throwing their opinion based on their guess...
