You could install a retractable wall or sliding doors of some sort? OR washable curtain panels mounted from the ceiling to open and close when needed.

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.)

Rui, On the contrary, If you look from the left it should align with the base cabinet because they are in same size. Most likely, it will go off by 3/8 of an inch after the dish washer (as it has been wiggled in). It is too small a difference to be noticed by average person because they are at different heights. We are suggesting to change either the cabinet above sink or the single box above right of dishwasher. It will be easier and the filler will be least noticeable above the sink as the shutters are already of a different size. Good news, is that you may have the cabinet boxes already. You can check by placing them starting from the left most wall whether the above suggestion works for you. Thanks, Nitin Cornerstone Designs, Bangalore.

Thanks for both of your responses CUBSpaces team and Shweta from Shades studio. It really gives a clarity about possible consequences. I am now doubt free about changing whole things in Bathroom as it will be interconnected. However will appreciate your opinion on few things: 1. Kitchen wall tiles: I have those from countertop height to roof(almost area of 6X15 feet) which are good and not hollow. I changed countertop 5 years back without any damage to these tiles. It might cost me another 10-15 K, but I feel the whole process and quantity of wasting old good tiles makes me little sad. 2. kitchen countertop: Made new around 5 years back. I don't expect to get it all intact. But large pieces can be cut and can be used as top for other freestanding structures like dishwasher, front load washer, heighten base cabinets, etc. 3. Plywood: I don't mind giving enough labour charges for old sheets recycle. I am planning to use doors, loose sheets(like kept on bed frame of settee frame.) or parts of big frames like settee. I am keen on reducing waste than to save money. You can see various DIY ideas by western people, who remove or sand laminates and re-paint furniture, or carefully remove hollow tiles and re-attach them. Some are also re-painting ceramic tiles. I am just asking myself: Are we creating more and more waste by use and throw approach every 10-15 years, just because we can afford it?
