Just to clarify, you have presented 3 versions. I believe the consensus is the original version with the wood grain ( linen grain) cabinetry works the best and is most updated. The only thing that is out of place are the cabinets or "shelves" on both sides of the range hood. If this is what you need to find a solution too. I would suggest only experimenting with rendering options for these two cabinets( or shelves). This cabinet ties in all the other hard surfaces. The white is not working. It just adds another element. The black is a little dated.

What a beautiful house, Shahbaaz! I live in a similar house - a 150-year-old colonial bungalow in Kumaon. You have already received lots of excellent advice from better-qualified people, so all I would say is, keep its age and heritage character the central theme. The white tiles do clash, I am afraid ... flooring with terracotta tiles would echo the roof and look lovely. The columns and the arches over the doors and windows are amazing. But I'd say, leave it all chuna-painted - there's a beauty and softness to it. Don't let the painters add too much neel (indigo) in the limewash -- in the hills where I live, they put far too much if I don't watch out and the result is a harsh white. Natural lime has a softer, creamy look.

Your setting is good but could be better.the centre table is a misfit.you can use 2 level rectangular table either white poly paint one level and the other level glass or black paint or poly paint.keep the length of the table after leaving approx 16 to 18"on either side.the width can be20-22 " and ht 16".the cushions can be change to black and white design,with a dash of red.a nice rug with grey,black and white geometric design will enhance the effect.brown does not go well with white.i hope this should solve your problem.once you make this change.you eye will pick up the other flaws.

For the wall in the balcony I have shortlisted two stones A) Black leather finish granite B) Grey William granite. I am posting pictures of both. What can be pro and cons as I am looking for the exteriors wall only. Further for there will be window and steel/glass grill at wall of balcony so not sure whether book match pattern of grey William stone will work or not. I request whoever reading this to suggest which stone will look better at my elevation wall. Thanks a lot for reading this. Looking forward to get some positive suggestions.
