Just a little ceramic information to share as a potter. Vitrified simply means the clay has become glass like by being fired to its proper maturing temperature. Usually ceramic tile means it is a lower temperature clay like earthenware or terra cotta. Porcelain is fired to the highest temperature and is more vitrified if you will. This usually means it is less porous to to absorb water and harder. Low fired ceramics with glazes much darker or lighter than the clay body will show chips easier. Rectified has to do with making the edges precise enough to fit smoothly together for less grout lines. So porcelain cost more to produce but it is more sturdy. All clay tiles should be vitrified.

I would take away those top arches and have builtins either side of fireplace, have the tv placed on a shelf on the built in, like in the pics, you don't have to have it above the fireplace, if room is small it will feel like it's coming at you lol. Panel above fireplace and hang some artwork or a nice mirror. Quiet like the builtins with the back wall painted

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:

Hi Nishi, Beautiful furniture and a very cute cosy nest you have. To begin with replace your existing coffee table with a hard wood simple coffee table. Replace your cushions with an assortment of pink, turquoise and golden yellow in different sizes and shapes, this will add some brightness to the room.Replace the pictures on the wall with a big mirror as per the wall size and add a nice frame to it. On the shelf on the picture wall place the candle stands currently on the centre table. The stools can be replaced with a nice upholstered ottoman bench in a printed fabric as sofa is plain. Cover the entry door with curtains as well so that it gives an illusion of a single wall behind. Since the wall behind the bench is already textured do not put anything on the wall. Remove the white bench there, instead put two big white teracotta pots there of different height and put bamboos on it. Finally put a blue/brown shaggy rug below the coffee table to complete the look. Hope you find the suggestions useful. Also you could put a few glass shelfs on the wall behind the 3 seater and place all your small knick knacks on displayLike how I have done on my wall
