For the overall here[it's a social floor plan-casual] I'd do a U kitchen-sink wall is the middle of the U. Reason is that people migrating in from deck and from family and dining area can use the right arm of the U as a peninsula with stools. Great spot for seating. You'd still be able to have 8 feet width inside the U it appears. Place fridge on lower wall backing up to closets...sink and range inside U-sink about where it is,maybe center the windowscape and range on wall that backs up to corridor over to the left. The island as you have it isn't desirable to me. the range on the left wall means at the peninsula you can do something more visually appealing with pendant lights/back side with panels or whatever to work with some stools and also have just a little separation from the cook's part of kitchen. this will be appreciated I think especially if the dining zone is the only one you are planning. Activities at the range with lots of counter around it will be a little more removed from the middle extremely open part of kitchen where you are suggesting it. You could plumb a small 2nd sink down on lower wall with fridge-perks to that as well.....stylish little zone with added pendant light carrying the theme from peninsula.

Overall, it's a pretty good layout - once you move the Cleanup Zone off the island and the Prep Zone onto the island. . Some things to note: Regarding aisle widths...aisle widths are measured counter edge-to-counter edge or counter edge-to-appliance handle -- basically, b/w items sticking out the farthest into an aisle. Your layout appears to be measuring cabinet-to-cabinet, which means your aisles are at least 3" narrower than you think. You need to account for the door & counter overhangs - usually around 1.5". So, b/w the range wall and the island, you really have only 45" counter edge-to-counter edge and even less b/c the range door and handle stick out even further. Refrigerator and Freezer...are they built-in? If not, they will stick out further into the aisle than you show. Most counter-depth refrigerators are actually around 30" deep (then you need an inch or more behind it for air flow, power cord, water line). The only "counter depth" part of a counter-depth refrigerator is the refrigerator box/carcass. The doors must stick out past the surrounding items (walls, counters, cabinets) to open fully and allow you full access. Some of the higher-end CD refrigerators are closer to being true counter-depth as are built-ins. I don't know which you have, but I wanted to bring it up b/c it will impact your actual aisle width. (Standard depth are usually around 36" deep.) Table and island aisle...be sure you have at least 60" (5') b/w the island counter and the table behind it. You need to have room for people sitting in both locations and have room for (1) seating at both island and table and (2) someone to pass b/w them. Prep Zone on island...As others have said, you generally do not want to center the prep sink on the island. One of the biggest advantages of an island or peninsula is the wonderful extensive workspace they provide - and accessible from multiple sides. You don't want to break that up with a sink stuck in the middle. In addition, Prep Zones should have a minimum of 36" of clear workspace - and 42" to 48" are much better. Prep Sink Location...Whether you put the sink all the way over on one end is personal preference. Some people like it on the corner b/c then they can access it from two sides. However, having landing space on both sides will give you more landing space options and prevent accidentally pushing things off the counter onto the floor, That space will also minimize splashing water onto the floor. ... My preference is at least a 15" cabinet on one side of the sink (18" are better) and then at least 42" on the primary working side, Prep Sink Size...the interior of the prep sink should be at least 15"x15", which means an 18" sink base. If you have the space, then one at least 18" wide is recommended (21" sink base). If you have a lot of space, I would go for one that fits in a 24" sink base. Seating overhangs...should be a minimum of 15" of clear knee/leg space after accounting for cabinets and decorative doors/end panels. Note that this space cannot be shared by two seats on a corner - each seat needs its own 15" of space. You appear to have 17" (18" - 1" for cabinet doors = 17") and no shared corners, so you should be fine. Seating space...each seat needs at least 24" of linear space. So, for 4 people, the island should be at least 8' wide. This is assuming you don't have island legs, etc. getting in the way. Space taken up by island legs do not count toward the space needed for a seat. In addition, with legs, you need a few more inches to allow someone to maneuver in/out of a seat with the island leg in the way. Your island is 10' long, so 4 seats are OK. If you want to add 4" legs, I would not add anything more than a leg on each end. As to using legs to separate seats - first, it doesn't work to keep kids from fighting; second, you are drastically reducing the flexibility of that seating by constraining seats to one small space; and third, you will need to add another couple of feet to the island to accommodate the legs. Some things sound good at first thought, but when thinking through all the ramifications, they aren't always that great overall.

Thanks all for the thoughtful feedback! @mama_goose: We are planning for granite counter tops. As for storage planning-- we haven't gotten that far yet. Now that we are pretty sure we will stick with this general layout we will need to go through buehl's "Planning for storage" activity. Thanks for taking the time to sketch out the potential island modifications. @buehl: The entrance from the garage is right around the corner from the fridge (the garage entry door is just barely shown in the original picture. Thanks for the detailed response regarding the measurements. @practigal and others: I don't know if I can justify buying 2 dishwashers!! :) @dan1888: We've considered a CD fridge, but not sure if it will be right for us. I've also wondered about recessing the fridge into the wall. It looks like we only have a few inches of wiggle room before the right fridge door would hit the wall though (as also highlighted by buehl). Thanks again everyone. Your input is much appreciated!

OK here's another suggestion without changing out the front windows. I do love that large window and I think it will help with light into the kitchen. I extended the foyer wall and moved the stove to that wall. I moved the opening from the hallway up a bit and added the fridge there with about 3" of room on the end so the fridge door opens. The sink is in the same place it was. Didn't move it. Moved the dishwasher to between the sink and the fridge. Shortened the island. It's now 6' long and will seat 3 comfortably. Moved the prep sink over a bit so you can put things on the end of the island before washing. So now you have two excellent spaces for prepping food. Or if it were me, I'd probably ditch the prep sink on the island and leave the island "bare" and instead get a large prep sink like the Kohler Prolific. It's about 45" long and if you put two faucets on it, 2 people can work at it at the same time. BTW: You can also get a dining table that is wider than 36".
