Very nice! But there are a couple of things (mostly upstairs) upstairs that would bother me. 1) From the loft area, there is no access to a bathroom, without walking clear thru one of the bedrooms or making a long trip downstairs. 2) It is a very long journey from the central bedroom (the one that is over the craft room) to the toilet in the J&J bath that bedroom shares with the back bedroom. From the most probable location for a bed to the toilet, it looks like a distance of about 25 feet, thru three doorways and requiring several half turns. I would not want to navigate that journey in the middle of the night, particularly if I woke up feeling nauseous. 3) If/when you finish out the future bonus room, do you plan to add another powder room up there? If not, getting to a toilet from the bonus room will require a trip downstairs and thru the length of the mud hall. 4) There is no easy access from the upstairs bedrooms to the bonus room. So, the bonus room is NOT going to be a natural common "play area" for kids or teens because it is simply not convenient to the areas where they are likely to keep most of their "toys". You MIGHT be able to solve some of the above issues (that is, if you agree that they are problems) by making the J&J bath a hall way bath. And, downstairs, I'd probably want access from my craft room to the foyer...just because I imagine that that would be where I might spend significant time during the day when someone might come ringing the front door bell. I think it would be nice to be able to answer the door without having to make a long trek around. Might not be an issue at all for you tho.

Here's the Island.

I'm concerned that you are going to find that your deep drawers under the baking center aren't big enough for what you want to put in them. With our 36" high counters and frameless cabinets, we have a bit over 28" of interior height in the boxes - the rest of the 36" is toe kick, cabinet box top and bottom and counter thickness. With 30", you will have about 22" to play - or less if you have framed. Your picture shows 3 equal size drawers - that means 7 or maybe 7.5" drawer face height. It varies a bit depending on the exact drawer construction, but interior drawer height will be about an inch less than that making your deep drawers about 6" deep. We have an 18" wide drawer stack for baking supplies. Our flour and sugar drawer interior is 10" high and 15" wide (those pesky cabinet box and drawer sides take up the rest). We decided on that height after measuring convenient flour storage containers. At that size it can hold a container with the sugars and 2 5-lb flour containers and a few smaller bags and boxes or 1 5-lb flour container and more smaller bags and boxes. We have ended up doing the latter. Our bread flour (because challah gets made every week) is stored there along with corn meal, cocoa, flax seed and some specialty flours. All purpose and whole wheat have to be fetched from the pantry. I wouldn't want to go any smaller than that. BTW, that is in our bottom drawer - since the containers are mostly tall, it requires less bending to get them than having small stuff where you need to reach to the bottom of the drawer. A slightly shallower drawer (7" drawer front) holds other baking supplies like baking powder, baking soda, etc. A much shallower drawer can hold a lot of the utensils. Our main pot and pan drawers are about as deep as our flour drawer. One 36" x 11" (drawer front dimensions - interior about 33" by 10") drawer holds a pretty complete set of everyday pots and pans (we have one for milk and one for meat plus a couple of smaller drawers for parve). Therefore, rather than having three drawers about the same height, I'd suggest a deep bottom drawer (10" interior depth at least), a medium size (~6" interior) middle drawer and a shallow top drawer. That's if you are going frameless and your cabinet construction is similar to ours. For framed, it might be best to go with just 2 drawers per stack. One use for the 9" cabinet by the range would be storing flat pan items such as cookie sheets, baking sheets and cooling racks. If they are half sheet size laying on their sides, that would take up the bottom 13" of the cabinet. We have ours in a 12" wide cabinet and 6 of each plus a couple of muffin tins take up the bottom. We have a pull out for other cake pans above. It might be tight to do 2 levels of 13" high flat pan storage. If you had a fixed shelf in just the right spot, you could do it. Our cooling racks and muffin tins are less then 13". You might do the bigger sheet pans on the bottom and smaller ones like muffin tins above. Cutting board storage is another possible use. Our food processor accessories are in a custom insert that my husband made for a pull out in another 12" cabinet. I don't think they would fit in a pullout in a 9" cabinet, but maybe if yours is smaller they might. 16" is very deep for a bookshelf. Is the cabinet to the right of the range all bookshelf? We have 12" to the left of our rangetop. It isn't ideal, but it works for us. What is the rationale for wanting at least 16" to the side of the range "for safety" when 4" at the back of the range is okay with you? We have an island rangetop and really like having the rangetop and prep sink on our island. But I'd rather have a foot of counter behind the range. If you had the space, you could do 12" deep cabinets on the back of the range. Rather than looking for cabinet companies with nifty inserts, I'd look for how they use the space in the cabinet - how much interior space do you get for a particular size cabinet or drawer. I think that the microwave will be really difficult to use where you show it. It will have to be accessed from the side making the panel difficult to read. Perhaps you are taller than me, but you mentioned kiddie cups so I assume that you have kids. That height and sideways access will make it difficult for your kids to use when they are old enough. I'd put it under the cabinet to the right of the fridge in the snack area. You might at least have an outlet there for it in case you find the other location inconvenient. The open shelves to the left of the sink would bother me. They will interfere with use of the counter to the left of the sink and you have minimal counter to the right of the sink. I'd suggest getting rid of them or doing only one shelf for more clearance between the counter and the shelf.

I basically like what you're considering and am posting to underline my agreement with no angled sink. I have that corner in a tiny vacation kitchen, and if I could make one major change to that kitchen within its footprint it would be to sacrifice what minimal counter space I have to its right to set it in next to the refrigerator. Note that an angled sink removes inches from the front counter edge to stand and work at, making the entire space work smaller, and it shifts precious counter space to wasted area behind the sink. (I'm short, so it's especially wasted.) Go ahead and measure the counter edge inches with both layouts and see. Creating one very good, pleasant work space--which you do have in excellent position between sink and stove--would be my first priority. So I'd set the sink on the fridge run wherever you want it. And if the DW has to go under the prep run, oh well. Disadvantages would be offset by the real advantages of a compact work area which are seldom considered these big-kitchen days. Btw, I predict you'll love your spice and other shallow storage across from the stove. :) Addendum: I forgot to mention that I'd strongly consider effectively abandoning the corner space under the counter, instead running drawers right up to the corner on one or both sides depending on where the sink was set. My home kitchen has an 18-inch drawer-and-door to provide access to a susan, and even though I think building in a few deep knee bends is a good thing, I'd trade it out in an instant for a high-efficiency 18-inch drawer stack. (I do have a basement pantry for large, seldom-used items.) I'd also seriously consider putting drawers under the sink. that's extremely, extremely valuable space RIGHT THERE, and just a little kind of the custom attention you've given to between-studs storage would secure it for items you use right there. Most of the chemicals and whatever that typically occupy that space would be better off on broom-closet shelves somewhere else.
