As far as spacing between the pavers, you want a minimum of 3mm or ⅛ an inch, but the ideal spacing really depends on the whole space and how you want to fill the space between pavers. If you are thinking about pea gravel or sand, you probably want less space between to help keep your costs down and make it easier to power wash. If you are looking to add greenery then more space between the pavers gives you more green, creating a more natural-looking space. If you do decide to go the gravel route, you can apply a clear coat of something like gravel-lok. It acts like glue, keeping the gravel in place. It may not be able to take the full force of a power washing, but it will certainly hold the gravel in place better than not having gravel-lok. If you do want to go for a green option, grass could work, You could also look into small succulents, moss, or clover. With any green option, you will have a little more maintenance in the form of trimming and watering, but the look is stunning! You absolutely can put grass between the pavers. It will actually help stabilize and hold the pavers not move them. (if installed correctly) I would space it 4” apart and use netfin or a similar subsurface drip line to water the grass underneath the soil. This look is probably my favorite but you could also use a crushed aggregate in between too. Gravel is a terrible idea because it doesn’t stay in place. Here are some ideas from our projects of all kinds of paver designs:

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

I really liked the indirect lighting and the bar light fixture.
