they wanted to turn the corner w the counter probably, which could have been useful to them. Inside..maybe just stacked papertowel rolls/toilet paper/ large bag dog food/ there's always usefulness in that way. but without the need for the extra bend in counter..think how much more useful a stack of drawers ...wider ..on the right would have been with no corner issue. that why galley kitchens w their straight runs/ now w drawers being universal, are hard to beat, as far as simple configurations go.

If you don't have a tray cabinet. I would think about purchasing some after-market tray dividers to install on both sides of the pie shape opening and forget about accessing the cavernous space in the back.

I had one of those in my previous home, though the doors were about 12" wide each. I kept flower vases, art supplies (for my visiting grandchildren), etc., in there. Less wear on the door if you store things that you don't need often.

In our new home build, we will have 2 sets of corner cabinets. Like yours, one cabinet will be near the range. I will probably keep large soup pots & pans in there that are rarely used.

The other corner cabinet will utilize one of THESE.

Here's an informative video for your situation.

Those corner cabinets hold an amazing amount of stuff, but getting to it is difficult. I had "super Susans" in mine, which I ripped out because I can fit far more on the shelves than on the rotating round trays. I like the suggestion of paper towel storage!

I actually really like lazy susans. I agree in an ideal world I'd prefer a galley-style kitchen - but if you have cabinetry that turns a corner, I'd rather have a lazy susan over dead space.

Are you making changes? New cabs and counter? Wide drawer cabs where possible would be an option to consider, No corner cabinet.

Is this kitchen under construction? Is that the actual pic of your cabinet?

That is a standard corner cabinet and Super Susans work pretty well to organize things in them.

Had one like this in previous house. The doors were attached to the pie shaped wedge and the whole unit turned around so you could actually access the stuff on the susan. You could probably retrofit something like that. It's a little hard to tell on this pic because the L-shaped door is partially hidden, but the whole door spins around inside the cavity.

We also have one at our lake cabin. It’s amazing how much the lazy Susan holds.
