This is your kitchen designer’s job. The availability of the parts and pieces of your bulder’s cabinet line is only known by your kitchen designer. Basic cabinet lines cannot do things that mid grade lines can do, and they can’t do the things that the custom lines can do. Do not forget the code required electrical outlets that need to be on both ends of the island. They occupy space that has to be accounted for in the planning.

The builder has the ability to go fully custom. I am gathering ideas now so that when I meet with the cabinetry team I have an idea of what I want without unrealistic expectations! I have already been asked what I would like to do with the extra foot of space in the island base. The other “drawing” is a complete mock up and will likely change just shows that I am doing mainly pots and pans throughout the entire kitchen.

Please add some of the extra inches to the isle between the island and cooktop. For me, it would feel super cramped at 42”. Actually it is less when add counter overhangs.

I would add 3” to the seating overhang making it 15”. I believe that is the recommended minimum for leg room if I remember correctly.

The rest I would add to the cooktop isle. You can play around with how much to add since the end of island countertop doesn’t have to line up exactly with the end of the sink runs’ countertop. I would do no less then 48”. More is even better! I think the isle between my island and cabinets is 52”. May seem huge to some, but it really isn’t. Two or more people can move around the kitchen freely. Like if Dad is flipping pancakes in front of the stove, someone else can actually get behind him to get the dogs’ food, throw something in the trash, or prep at the island and not cramp the cook. The scale is off but hopefully this helps explain.

I agree that a less deep island and wider space between island and cooktop/counters is a much better use of space. No to cabinet access under the counter overhang. That would be very inconvenient.

Microwave & walloven next to refridgerator which is next to a wall is not a good layout if there is a better option. Is that a walk in pantry? How about putting the microwave in the pantry and having a range rather than a cooktop and wall oven. That would open up the space next to the refridgerator and give you landing space for items going into and out of the refridgerator. Also, less congestion in front of the walloven and refridgerator if both are in use at the same time.

I agree widening the aisle while still adding some extension to the island is probably the better idea. I use my oven tons and having an elevated one is much more useful for me than landing space beside the fridge when I am more than happy to use my large island as a fridge landing space. We also often use the stove at the same time as the oven so the ability for someone to gain access to oven while the other is using the stove is very valuable! We don’t often use the microwave so we will keep it above the oven as we already have plans for several other appliances we will be keeping in our walk in pantry (we will have a countertop and outlets in the pantry along with ample food storage)
