What do you need to store in the kitchen proper? You already have crockery storage and food storage elsewhere. Just tally what you actually need to store and provide space for that. You may not need all built-in cabinets; shelves, hooks, or pegboards may do as well. And yes, the utility room is very tight....it look like just a 24 in (600 mm) wide passage? I'd scrap the sink rather than squeeze it in so tight. Do you really need separate spaces for utility, kitchen and store? If you combined these all and planned them carefully, you could have a large, very functional kitchen, at least by US standards. (Not being familiar with exact kitchen norms in India, I can't fully comment on the tradeoffs.)

I have a hard time seeing a true color on my PC, however I think the shade of this color is too much like the shade of your lovely cabinets. It may make it very dark. Do install under cabinet LED lighting on dimmers whatever you do.

I am not a designer. Not every house has to have a hallway but I wonder about efficiency problem: people crossing into dining table/chairs to get beyond to another room. There just has to be enough room I guess.

this is looking good. finally someone on houzz has listened! Thank you. I would leave it as it is since any items you place up there needs to be maintained and that is one more task we would be adding to the lady of the houzz. but if you are still wanting to add something for that first client impression may be few large glass pickle jars or just two of three colourful glass sculptures. as would perhaps know - less is more in modern design.
