A wood stain cabinet. with stain factory applied is I think the easiest to maintain. If you like white cabinets, make sure that the white is factory applied, too. Cabinets that are painted and / or stained at home, do not have as durable a finish as factory applied finishes.

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.)

You should be able to get everything that you want ........ Are you going to have a cabinet maker build it for you ? I suggest that you work with them and have them draw it up for you........Most cabinet makers are very good at working with their clients to get them what they want.

too tiny kitchen for island. need to have accurate floor plan and water source for sink design along. foldable table might work better with counter wall in cabinets. island counter with ceiling hang chimneys if cook top here may save space OR simple counter table with utility below and just one wall touch kitchen platform so have a corner for other cabinet or fridge.
