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.

Hi, this is parveez from best interiors , island type of kitchen , it will look good but the combination should be a light one in colour thn it sounds good

Totally doable as long as the island is not too bulky. And of course if the circulation space around the island is at least 3'-0" wide. You don't need too much space to move around in a kitchen because you should be able to pick up a hot dish and put it down on another surface without having to move too much. 12'x14' is a large size and a work island would possibly make the space more practical to use. In the pictures attached, the work island is only 2' wide but 4' feet long

Ruhi, it's a good size kitchen you can go ahead with an island. You can share the floor plan for more details. Thanks, Nitin Cornerstone Designs, Bangalore
