The island works in the plan provided, you might even make the island longer. 42" clearance will work between island and cabinets (36" if not much trafic, and no appliance door swings).

Hello there, Since you have put an all white kitchen with recessed lighting, you won't be needing much lumens for the island. As for the length, two small pendants with 12/15W lamps spaced 2-3' apart would be enough to illuminate the space. It's always better than one large pendant because it disperses light over a larger area and aesthetically pleasing as well. Regards, Aurum Ideas and Spaces India

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

Pencil interiors, 12x14 is by no means a snall kitchen space. An island of decent size can be accommodated unless floor plan has some typical challenges . Thanks, Nitin Cornerstone Designs, Bangalore
