Hello there, When you are going for wooden and concrete texture, the decor you need to put must complement the interiors. If going for traditional and rustic finishes, athangudi tiles would really help for outdoor and indoors as well. They go seamlessly well with wooden textured tiiles/ wooden floors/ Try to add wooden rafters/ slats to sitouts and balconies to enhance a few aesthetics. If going for contemporary finish, try IPS (Indian Patent Stone) flooring for outdoors and indoors as well. These are basically concrete slabs with iron oxide paints on top and come in a wide array of colors including copper sulphate blue. If planning for cement tiles, try Bharat Floorings . They have been manufacturing concrete tiles for almost century. Blue with wooden, if used generously, lends a beach house/ marine theme to overall decor . If that's your preference, then do not hesitate for a moment. Regards, Aurum Ideas and Spaces Bhubaneswar
