The style you like seems to be cantilevered into the wall for stability - depending on your available options you can use solid wood - but the more stable option is to clad it ! Just remember that not everyone likes the way that it's seems very open - so may limit your buyers if you plan to sell in the future !

Anita Vitrified tiles by themselves do not particularly allow the walls to breathe, and hence are prone to cracking. That being said they do not collect moss either. If you are however set on using these tiles, I suggest you use them in a mosaic fashion, where smaller tiles or broken pieces are used. This will allow the wall to breathe, though the moss collection might be more due to the greater amount of grating.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

If you are looking for high quality stine wall cladding tiles. You must go for the stone evolution which is situated in Udaipur. I have worked with them and they have given me the best quality at the best price. The natural stone wall cladding tiles are a game changer for your space. Highly recommend.
