Hi Vandana, although we agree with some points Minipie mentioned, but we think glossy marble in the house is just beautiful. Concerns that it feels cold can easily be solved by installing underfloor heating. And the fact that is glossy, we agree it can be slippery, but in the living room we presume you will have a nice big rug to make it cozy and non-slippery, but in the kitchen, that glossy finish will make it much easier to clean the floor.

I like the polished look, I have polished tiles from my entryway all the way to my kitchen and utility room, I have no problem with slipperyness. The key is a good entryway rug, cleaning up spillages and a good steam and microfiber mop. Your choice of tile will depend on your personal taste but I like the Greek key tiles. I think it will look fab. Also agree with buying a sample square to see how it looks before committing fully.

We have our open plan kitchen/dining/living room in wood effect tiles and the front sitting room in real wood. I wouldn’t want a cosy sitting room to be tiled in the UK, personally. UFH is great but doesn’t quite compensate for the look and feel of a naturally warmer surface and also you can’t use thick rugs without compromising the UFH effectiveness. Equally, I’m so glad we didn’t put real wood in our main room, given the amount that gets dropped on it. Hallway is also tiled, again wood would have got trashed there.

My friend has the large white porcelain tiles throughout ground floor of her open plan home with underfloor heating. They look great in a contemporary home - cleaning is not a problem - white/light coloured tiles are easy to keep clean unlike black tiles, which are a nightmare (if they’re polished porcelain). She has 2 kids and 2 dogs and the floor never looks grubby so I would say go for it if you love them. As above posts, the starkness can be broken up with rugs, plants etc.
