Mustafa, my apologies for the delayed response! I've been thinking about your dilemma and this is what I've come up with. I'd make the most of the vertical space in the room so that you allow yourself maximum square footage for counter work space. If you're able to, I would suggest putting the refrigerator on the opposite wall (where the tall storage unit is in the sketch). Something similar to this:

Work with someone in your location who designs and provides kitchens. If you location is not in the U.S. cabinets sizes and appliances are very different and info will not apply.

ya... as. i said earlier go for same layout with centre opening. keep 2' counter on outer wall. if possible go for open kitchen. that will give little open feeling and along with ur dining space, the area will loook bigger. As i see in the plan utility area is missing. If u want , instead of store u can go for utility.

One Follow-up question.. Is there any strength issue with 20mm Granite slab over 40mm Granite.. Are the 20mm granite slab prone to chipping or crack on normal usage.. Usage would be like, chopping vegetables, keeping hot vessels,.. The normal usage what happens in normal indian kitchen.. I just want to be sure that I decide based on experts judgement (like you), as people are just throwing their opinion based on their guess...
