I assume you mean this inside corner.

It’s a toughie.

Remove the door(s) behind the dryer and make it a solid surface to match your cabinet end panels, since you can’t open the door anyway. Then, make the blocked area accessable from the next cabinet to the right. You could slide biggish items in there, like coolers or suitcases (something with handles to make them easier to remove).

Maybe someone more clever than me can come up with a better plan.

It's okay to have empty cabinets.

I love the random red sink! Forget the weird unusable cabinet and have fun with the red. Maybe paint the window trim red! Or put bright red cabinet pulls on the cabinets. Or maybe add red wallpaper.

I wasn’t sure about the red? But I could be swayed! This was my inspiration image.

it looks like your inspo photo. Just leave it empty.

Would have been nice to have the sink under the windows and W/D on a solid wall with a closet rod above. It's done, and matches your inspo! Success.

Oh, the double sink is handy, if it is as big as it looks in the photos. With the farmhouse sink, using a plastic dishtub when necessary will be fine.

If you are replacing cabinets, don’t worry about turning the corner back there with the upper, just let it die into the wall. And if you leave it open under the counter, you’ll know where to look for missing socks and dust bunnies.

I love the inspiration floor!

There are 13 other cabinets and four drawers. I'd ignore the problem.

My perfectionist brain has a hard time ignoring!

It looks like without the cabinet door, it’s easy enough to reach inside, so I might just have a big low sided basket in it to hold all my hangers

Good advice already - I would probably remove the doors and drawers and use a curtain, then store very seldom used items in there

Great idea!! Thank you!

I was going to suggest removing the doors and using it as an open shelf. Baskets too if they fit. I see others have mentioned that.
