Herbflavor- I will try the 3 sketches. I've heard of the Liebherr, might be a bit out of range, $3000 for a freestanding 24", also sounds like service maybe expensive too. I do like the counter depth and compactness it would provide though. Katsmah- great idea, although the fridge door swinging how it does makes easy access to beer when I'm in the next room over (living/dining room). Moving the fridge towards the right may address this though. roarah- Another great idea! Except my sink/cooktop wall is an exterior wall, I may not be able to do this depending on what's behind there, but I can do it on the opposite wall. Also- a standard studded wall is 3.5" deep, how did you fit a toaster here? fori- Aisle is 49" wide from edge of existing countertop to countertop. I may be able to get a few (3) more inches by taking out studs on the fridge wall. It's a non-bearing wall, I planned to do this with the 'fridge anyhow so it doesn't stick out as far as it does now. I'll see if I can fit 30" depth cabinets but I dont think there's going to be enough space, not to mention the added expense. Yes, cabinets all the way up to the ceiling is in the plans, and yes I can, there's nothing behind there but air. On the existing fridge wall, the soffit stops at the pantry. I made a graph paper sketch, I'll have to find it and scan it.

Use a kitchen designer either remotely or local to you. Getting the design right is critical. Also, please make sure you pull a permit to do the changes. Here in my area permits are required if you are moving plumbing and electrical around - but not if you don't move those items. Here it would be a real problem with code enforcement which can fine the property owner up to $1000 per day. I mention this because many people aren't aware that if they didn't pull a permit to remodel/change their space there are steep fines. Check your municipality's building department so you have accurate info from your town.

There seems to be a lot of space wasted on hallways on the kitchen side of the house. If it were me I would put the kitchen where the dining room is, and have a great room open area with living/dining side by side and a larger kitchen. To me an eat at island, plus breakfast nook, plus formal dining room is a bit overkill. So I'd move the office to the breakfast nook, and use the old office space as the pantry, and use the old pantry space to expand the guest bedroom suite. Here's a quick sketch. I traced your floorplan so it's approximately correct.

Wow, your dimensions are very similar to my house, although we have no basement and a prior owner did an addition off the back. The good news is that you can do a lot if you're prepared to utilize space from the dining room for the kitchen. There are (at least) 3 factors you need to think through carefully. One, opening up the wall between the kitchen and dining will make your kitchen visible from the front door. Not everyone likes that; for us, it was a perfectly reasonable compromise and I don't have a single regret. Either way, you want to think about the design with that perspective in mind. Even more important, you need to get the function right. Opening up the wall would give you 23 feet of length ... but it could mean a huge trek between the sink, range, fridge, trash if you don't plan carefully. Do you have a staircase to a second floor - does it run above your existing staircase? Finally, your budget looms large here. Opening up the wall was less exorbitant than I initially presumed, but in a small old house there are lots of costs I didn't initially anticipate. Your windows may need to be moved/resized among other things. I joined Gardenweb thinking we could just replace our existing layout and estimated it would cost about $15k. The eventual cost (including a heavy up, opening up the wall, and moving the gas and plumbing on a slab) was at least double that, and we'll add a bit more storage and counters in an upcoming addition/remodel. For us this made sense; we're here for the long haul and we still have one of the least expensive homes in our zip code. But YMMV. Finally, take a look at these two kitchen reveals that I remembered from wayyyy too much time on pre-Houzz Gardenweb. The first one looks larger than yours, but it's worth looking at since they did such a nice job of expanding without completely blowing out the wall separating the kitchen and dining: Cape house kitchen reno (So does this more recent one btw.) This one has a different layout than your kitchen but it shows how you can maximize every inch of a tiny kitchen if you plan carefully: beautiful small kitchen reveal I found this one when I was looking for the links to the others, another great example of what you can do with a very small space: tiny kitchen/dining reveal
