Not sure what we're looking at here - is this the entire kitchen area? Why aren't their any drawers? Range goes where? Be careful with installing your cabinets too high - will you have difficulty reaching the second shelf? I'm only 5'3" so placing cabinets 24" off counter top puts me at a great disadvantage. Sorry eagledzines! Check out Hafele cabinet hinge options and see if you can incorporate any of those....

there is no perfect dimensions for an island. Try to organce space subdividing into smaller cabinets of 60x60 cms which is the max space for a structural division and works for seating area as well

One option, I would get a very large rug so that all the chair legs and at least one corner of the sofa is on the rug. I think I would also bring the table set away from the window a little more. I think there is enough space to place the two-seater opposite the table in front of the window. or bring the table forward toward the kitchen ....... With the sofa centered to the large window. They probably will not be opposite each other, but at an angle which is still ok. They might seem more functional for the table set to be closer to the kitchen. Another option is two rugs in wide runners. Creating a walkway through the center of the room. Still thinking the sofa center of the right window. Just some ideas :-)

acc to ur kitchen cabinet pic, I would request u to get stone ( kadapa ) vertical base frame and on top before granite fitting and then wooden panel can be done for drawers n shelves. this will eliminate wood to get wet and start to fall apart. looking forward to modular version need to know it last few years only. wherever water is concerned only wooden panels won't work for longer n steady use. for counter tables or side working space that will work but not where the sink will be placed.
