I cannot read details on your plan, but I have a few questions to start things off. Those better at this than I will follow. 1. Do you want to cleanup on the island? That is where the DW is, I think. And do you want to prep on the blank perimeter wall where the other sink is shown? I wouldn't. 2. Do you need two such large sinks? I wouldn't. A smaller sink on the island for prep, a single sink large enough for any cooking utensils for cleanup. I would not want a double sink. 3. Why not make the island wide enough for seating as you perhaps suggested? With the space you have, I would. 4. Are most of the base cabinets drawers? 5. Is there a pantry somewhere where you can store cleaning supplies--mops, brooms, vacuums? The 2 foot wide one seems skimpy. Can you repost somehow so we can read the details on the plan? Did your architect supply you with elevations? Can you post them?

In your latest, while the pantry access from the kitchen won't be quite as convenient, I think it will work. I think it's better than the one with only one entrance. Plus, it gives you a shortcut from the garage to the Garden room w/o having to go through the kitchen - which I can almost guarantee that people would do - and that they would cut through the main workspace instead of going around the island. I like it! I also like the idea of the appliance pass through - which makes me wonder if you could also use it as a staging area for things you want from the pantry to cut down on the amount of running around to the side door with your arms full - you might want to make it another foot or two wider to use it that way. Will the pass through have a door to hide the appliances from view when not in use (and to hide the interior of the pantry)? I do have two concerns about the pantry: #1 - You don't appear to have much real storage space. Do you really need that sink in there? I'd rather see that wall be all shelving for food storage. If you really want a sink, then put it on the opposite wall. Make the wall that's shared with the kitchen a row of cabs + counter with the sink. It would also make it easier for the pass through idea. #2 - The refrigerator & Freezer locations...First, the refrigerator may not open fully b/c it's against the wall and it might not quite fit b/c of the door frame/trim. You will need at least 6" b/w the wall and the refrigerator to allow it open fully - and then it will be opening into the doorway. Second, how wide is that aisle b/w the refrigerator and freezer handles and the opposite wall? You don't want to have a "pinch" point there since you will exiting with items in your hands/arms. I would try for at least 45". So, how much space do you really need in your office? I know that when I work from home, I rarely take up more space than that needed for a desk to hold my laptop + two large monitors + notebook space (yes, I still take hand-written notes!) You might want to take another foot or so of depth on the "bottom" to add to the pantry to give you a wider aisle. Inside the pantry, I would add another 6", at least, to the refrigerator/freezer wall so you can put a 6" pullout or similar b/w the refrigerator and wall. Idea! Why not take 13.5" and... From the wall, add 1.5" filler (to clear the door trim) Then, 12" pullout for brooms, etc. Then, refrigerator & freezer Then, shelving Finally, eliminate the "Broom" cabinet on the bottom and use that for more cab/counter space in the pantry.

Have your electrician develop a proper load calculation. Note that with gas heat/hw/dryer your big draw will still be A/C. Once you have a load calc, you can compute what the drop will be given the size of your service conductors. I can't imagine that 30' is going to make a big deal but you'd have to check (and see what sort of voltage the POCO is currenly providing).

From and operator style...yes. With that grid pattern...its tough to say. When you get into the ornate grid patters (as pictured above) they are often confined to those windows that occupy the top of the price market. That grid pattern would be a very expensive option in addition to the window. As an operator type, a fixed picture window with casement flankers is certainly available.
