I'm anxious to see what others suggest.

Totally off topic question though: What program did you use to make your drawing? I am looking for a free or low cost program to do simple layout drawings. Thanks.

@julieste floorplanner.com basic level is free

That's a strange one! Could you just get some inexpensive undermount slides and attach a piece of plywood to them (making a sliding shelf). Put slides on the shelf in the blind corner which would open to under the sink, then slides on the shelf under the sink. You would need to pull out the shelf under the sink to be able to pull out the shelf from the blind corner. I'm not 100% sure this would work, it would depend on the plane of the shelves in the blind corner and your plumbing, but that's all I got!

plastic bins would probably be the easiest/cheapest/least likely to make you lose a security deposit when you move out.

Put a lazy Susan in the far corner so you can just spin it without reaching in so much- meaning the large spinning trays, not an actual installed lazy susan

How about a piece of plywood with casters on the bottom? Or try googling "cabinet dolly" (a term I had never heard before but ran across in my search).

I wouldn't recommend adding a Lazy Susan so you can reach from under the sink. I love the new ones that was just recently produced but for your kitchen you would have to place your sink at the Island if your'e planning on having one.

A rental says plastic bins snd a flashlight. Save your money for the house you buy.

I wonder if you could use something like this: https://www.target.com/p/stackable-slide-out-drawer-organizer-medium-white-threshold-8482/-/A-76768961
You could put a couple side by side and/or stack them. But you’ll have to have a way to get whatever is under the sink out of the way in order to slide out the drawers.

I like the plastic bin idea. You really only want to put things that are large and seldom used there anyway. How about putting some storage on the wall of your dining area instead? You can find free or very low cost shelving, buffet pieces, or other storage units on lots of different sites, and you may even find some peices you like enough to keep and use in other rooms or ways later on.

Thank you! The plastic bin with wheels is very intriguing!

Definitely keeping lesser-used items there. Or maybe leverage the hard-to-get-to aspect and just keep the snacks and sweets there......

If there are bugs, the humidity under the sink plus drain hole access + snacks n sweets might be a bad idea.
I’d store someone inedible there where it’s ok if it gets a little damp or whatever on it (Ex. Toilet plunger, the jumbo cleaning product container you use to refill your smaller convenience sized cleaner bottles with, etc.
