2.5 year old post...and you still haven't found a floor? Local species are always best for local climates. India has different wood species than N. America...so our suggestions are going to be of little help to someone on the Indian Subcontinent. Local hardwood works best in local climates. Work with that theory and choose the wood you like the look of.

I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

Is the tile for the flooring? I would recommend long rectangular plank tiles, there are many different looks available here is an example of one project we did that gave the client a neutral design option, they are tiles that look like a textured wood.

You list is all "stone" products. Stone products are natural. The durability is guaranteed with stone. Stain resistant...remove marble and granite from your list. Both can stain and etch and both will do this with "flooring" more than they will with a counter top. Gloss levels all change...but it will take years to do it. All stones have maintenance = homeowner needs to work at keeping stone looking good. Stone = expensive. There is no "benefit" for "reasonable" when working with stone. They all cost plenty of money. Stone is expensive. No way around it. If you want "glossy" that doesn't stain for a "good price" then you have forgotten to mention the BEST option: porcelain tiles. Porcelain will do everything you want for a lower price. Stone is expensive, it can stain (especially "oil" stains) it will "etch" or lose gloss level with certain liquids (acid based liquids will do this) and they all need to be maintained and eventually need repolishing to maintain "gloss". Durable is all you can expect out of stone. The rest of your wish list belongs with porcelain tiles.
