I posted the first version two weeks ago, which included an 18' wide, 6.5 foot deep expansion off the back of the house. There were many helpful comments but buehl nailed a great layout for that configuration.
See linked thread if interested.

I will be presenting these 2 versions to contractors for pricing to see which type of expansion gives us the most bang for the buck.

Repeat information about us:
1. We are a family of five with three boys ages 21,18, and 15. The older 2 are in college. I would like to have a large kitchen for extended family and friends gatherings well into the future. There should be room for 2 cooks.
We do have a kitchenette in the basement with an additional full refrigerator for overflow.
2. My husband is insistent on a separate eating area hence the breakfast room addition. Dining room is needed separately and will stay as a dining room. I might like a few seats on the island for "visiting" with the cook.
3. We have a great backyard and would like to showcase that through the windows. In this design, it would be the breakfast room addition and in front of the cleanup sink. I would like the windows to go down as low as practical.
4. We do a lot of stovetop cooking and some stir fry as we are Asian origin. Planned appliances: 36" induction cooktop, 36" vent hood, 30" wall oven, 30" 240v advantium, 42" subzero SxS fridge (paneled), bosch dishwasher (paneled).

Version 2 expansion does not take down any walls; the existing 80" wide window in the breakfast nook across from the door to the front hallway becomes a large walkway/opening to a new breakfast room, perhaps 10x 10 feet? Existing breakfast nook space gives way to the main aisle to the planned breakfast room addition, the counter stool eating area, and the coffee/breakfast center.
.

I was really hoping to include an island but the aisles would only be 36" and 40", so I eventually gave up on that and went with a slightly expanded U shaped kitchen, with counter stools outside the "U". My brainstorm was to place a breakfast center between the walkway to the new eating area and the family room, complete with under counter fridge/freezer, perhaps a small upper microwave, and perhaps even a single dishwasher drawer, creating a coffee/breakfast/snack center. The prep sink in the peninsula is close enough to service that coffee/breakfast center.

There would be two prep centers- between the stove and the cleanup sink , and along the peninsula. The trash is convenient to both of those.

I have tried to include the aisle widths. Please let me know if you need to know any other measurements. Again, I welcome critiques and suggestions. thank you in advance!

Left wall against dining room is 14'2". width of the kitchen side to side is 18'2", and the depth between the wall of 3 doors and the outer wall is 10'4". That's why we didn't quite have enough room for an L shaped kitchen with an island.

When I get home late tonight I will post a corrected diagram.

Your suggestion would work great if my kitchen really had the external measurements that I posted in the first diagram! Sorry for that misleading information. I can't post the corrected diagram until tonight.

I should also mention that this new plan is very similar to my current kitchen setup- only adding a trash cabinet, and swapping appliances around- the fridge is where the cooktop is diagrammed, the cooktop is currently in the peninsula with a downdraft vent which I really dislike. Current peninsula overhang exists but is not used because the eating area is to small for a table and counter stools. So the "mockup" is already there. The real additions are the prep sink in the wider peninsula with the 24 and 12 inch cabinets back to back, and the breakfast bar.

Anyway...here's another idea for opening the kitchen up to the new addition. Sorry it's not prettier, but hopefully you get the idea :)

lavender lass, I like the open-ness of your plan, I had not thought of a galley layout. I'm worried about the reduction in prep space though. Those corner areas are my main prep spaces now and your plan would reduce the counterspace for prepping. Asian food requirea a lot of washing and chopping!
I did think about moving the tall oven cabinet over where you suggested, but decided against it because it would partially block the view to the backyard (a key item I want to preserve). This is really a "form over function" thing where I thought that the slight gain in fuction did not warrant the larger loss in form. thank you for thinking of it though!

Thanks for your thoughts about the screened room- good memory!
I had drawn out a plan joining the screened porch with the breakfast room in this plan but both current and former architects independently advised against a porch roof outside the kitchen windows since it would significantly change the great natural light and view that we have, so we will just have a deck in this plan between the breakfast room addition and the screened porch addition.

I hope I'm not sounding intransigent for your suggestions. I've had far too long to think about many different layouts and have tried most of them. However I know that I can't have thought of everything and welcome new thoughts. Additionally, it's definitely better to have new eyes on a plan to point out its flaws. So thank you again!

Here is the 3-D visual

If you're already doing a bumpout, it really will not be that much more expensive, and it might even be cheaper as it simplifies the foundation and eliminates the jog. Also, the kitchen would have a lot more connection with the breakfast area, which it now does not. I thought that was one of the requirements for your husband too. To have an "eat in" kitchen. With a bump out for the breakfast area away from the kitchen, you might as well be using the dining room, as it's actually closer and more connected.

Explore opening up the dining room to create that connected eating area that you want for everyday eating. Then think about the screen porch addition as the more "formal" area, with the connection to the exterior. Or, if you did the screen as a french doored addition to the dining area, the french doors could open to link the two spots for more formal dining and when you had parties. A table with lots of extensions could extend through the dining area into the sunroom and hold a LOT of people. It would be pretty nice for entertaining, and be a LOT cheaper to look at going that route.

You need to leave 5 feet between the edge of the counter and the edge of the breakfast bar. Seated people take up 2 feet beyond the counter edge (temporarily using 32" to get into or out of the stools) and you need to leave at least 3 feet behind them for passage and for people to be able to use the breakfast bar. are you aware the overhang for the counter as shown on the drawing doesn't match the size stated for it?

If I remember correctly, you're using the ikea planner but have no plans to use ikea for the actual cabinets? That sink is smallish for cleanup (ask me how I know), a better choice would be to plan on using a 27" to 30" sink.

You can't put a stages sink in a 24" sink base. The part of the sink that is less deep - in cabinet terms, is still too deep to have a top drawer in the adjacent cabinet. And you'd need to make significant cuts in the cabinet sides of both the sink base and the cabinet beside it. Even the small stages has an array of rack, board, bowls, etc that live on a rack under the less deep end. I'm not sure it would be possible to use the storage rack with two cabinet sides in its way. Plus - no rolling cart - or at least none over about 26" tall.

The dishwasher positioning means two things - you'll need to be careful to choose an integrated one to avoid having huge fillers in the corner because:
-- Dishwasher doors frequently sit in front of the cabinet line - even integrated ones. The filler on the drawer side would start out being 2-3" deep. Generally, with framed cabinets, the minimum corner filler is 1.5" on both sides, but dishwashers don't have cabinet sides or frames but you'll need to allow 3/4" for the corner overlap, another 3/4" to get beyond the cabinet door, plus extra to get beyond the dishwasher door.
-- Drawers perpendicular to a dishwasher need to avoid its handles. I have a bar handle on mine and it sticks out 2.5" beyond the outer surface of the dishwasher. I would need to add at least 2" to the filler on the drawer side - making it more like 5".
-- It is impossible to get into the cabinets to the left of the dishwasher while the dw doors are open.

This is a sorta galley without extending the room at all. If I could do something more, it would be to replace the former kitchen window with a door + transom. I'd put a small deck out there to connect better with the screen porch. I garden, so it would have steps so me and my garden produce and dirt end up directly in the kitchen.

Scrappy- You've said you need a lot of prep space for your cooking, so if you need that extra counterspace...what about moving the sink to the peninsula and having the space under the window, for your prep?

Using Bmore's drawing...maybe something like this?

From Cottage house plans

LWO- the breakfast room in this plan will be on piers (surrounded by a deck)or a foundation, it will be adding a separate room onto the back of the house using the existing window header as the support for the new doorway. I wanted to use this as an alternative to the 6.5 foot bumpout addition of the whole kitchen (18.2" wise) that I had posted two weeks ago. I may be wrong, but I think the costs will be mush less as no significant demolition of walls, much less plumbing and electrical work. The breakfast room addition would just have basic heating and electrical, no plumbing.

You are right that in this plan the breakfast room is more disconnected from the kitchen than in the whole kitchen bumpout, but it is still right by the family room and with the great lighting and view to the backyard.

Bmorepanic and lavenderlass, I think you guys have nailed it between you two, thank you. I'm going to spend some time thinking about your layout as I work in my kitchen now.

I do have one question though- why is 60 inches needed for the passageway through to the breakfast room? I thought that 44" was what was needed for walk through area behind counter stools. I have read a bunch of threads about distances between islands and kitchen tables and the recommended distance there is 60" but we don't have chairs on the other side of the aisle. Buehl stated that she has 54" and it is fine for a person seated on one side as long as noone is seated at the other side. I had thought that I would use the backless saddle stools which would nicely tuck under counter when not being used and also take up less space when being used.

thank you again!
