Here are pictures of our design. We had the same half wall and made it a penisula, that looks at to our sunroom/DR. If you have a large family I would suggest extending the penisula to the pole so you can sit 4-5 stools. Where is the 20 foot wall that leads to the sliding glass door? is that across from the 1/2 wall? Do you plan to use that as the kitchen or is that the DR? I would leave the sink where it is and work around it, especially since you have an existing window above it. I hope these pics help. I'm sure you'll get alot more responses. good Luck!

A paid professional will be your best bet. There's too much lacking here to get you up to speed on. You'll need the plans to file with your municipality anyway. I'm surprised that you began such an extensive job without having written plans, including those from an engineer to support all of those walls that came down. There may be some heat from the codes office for that. You are forgetting the human element in your plans. People need to have room to move through the space, and you are forgetting that most of all. A LOT of things you are proposing are below code and/or extremely poor design choices. Kitchens need 3' aisles minimum, and are better with the NKBA recommended minimum of 48". Baths need 60" minimum for a double vanity, and 30" of space for the toilet. You also have to have minimum walk spaces for each fixture. Humans occupy a minimum of a 2x2 cube when moving through the space. Chairs have to be pulled back to be occupied. Closets have to have room for people to access the hanging space. I could go on and on. Pay a pro. It'll be well spent money.

Oh, those are nice vinyl mats, april! Very nice. Are they cushioned? And what a great idea to tile under your cabinets. The unforgiving nature of tile sneaks up on you. I remember my MIL telling me it was a hard floor when we were doing our kitchen over twelve years and I scoffed. How hard can it be, I thought. She suggested vinyl. OMG. Vinyl! I turned up my nose at that. And also, I kept thinking of off-gasing. Well, I got my tile floor and then had to deal with the godforsaken grout. Thankfully, it's one of those tiles with a pattern that hides the dirt well. But the grout! I asked about sealing it when we did the floor but the contractor said it didn't make much difference. Besides, he said, you just clean it. And he's right. I do. On my hands and knees with a toothbrush. After a couple of years, I'd notice that I wasn't spending much time in the kitchen. Washing the pots and pans wasn't a 15-minute chore anymore. I'd give up after five mins or so. Finally dawned on me that I couldn't stand to stand in there for very long. Everything hurts. (We got a gel cushion mat for the sink area. I wish it covered the whole floor.) Never again. I'd rather have a water-stained hardwood floor in there than tile. If the wood got too bad, I'd paint it with marine-grade paint. Or I'd look into cork, linoleum and vinyl a bit more. Cork wasn't widely available back then. I can handle tile in bathrooms but not in the kitchen where I must be on my feet for more than a few minutes.

Yes we have lived in a house gut to the boards total remodel. DH who is in the business did the forming and carpentry work. The electrician we hired got all the permits and strung the wire for the electrical. We also got a certified plumber. We survived. I cooked and froze a million casseroles lasagna spaghetti and meat sauce. Did fresh vegetables to go with the casseroles and cooked on portable stove top and in microwave. We had lower-calorie but still Dagwood style sandwiches a lot. We couldn't afford to eat out and fix the place up. Our kids were three and four and didn't know any better thank goodness. My kitchen for the reno was my laundry room. We did that room last. For a countertop I got 2 portable dishwashers with a board across them. I had about 6 feet of counter that way. I had 2 rolling carts one for the microwave and food and the other one for the portable stove tops and food. Our fridge fit in there as well but it was tight. It was definitely a one butt kitchen. I think it was what kept us most sane though. Just having a home cooked meal made us feel like things were still in our control haha. I filled the dishwashers up and ran them in the laundry tub one at a time as the day went on. It made it easier to keep things clean as well I could pay better attention to the kids. (when I first read this I truly thought we were talking about cosmetic surgery on our tummies. I haven't been getting enough sleep for the last well 10 or maybe 12 years so that makes me possibly see things...I would love to lose my tummy. I'm told that no matter how much exercise I do the only thing that would help me is some kind of operation.)
