It's nice that you tried to create a floor plan and gave dimensions. However, the kitchen area you are asking for help with doesn't match up with the photos you provided. You say there is only 31" of floor space between the cabinets and the wall, but I can see at least 50". I'm guessing you measured the space between the refrigerator and the wall?

Unless there are cabinets that I can't see on the wall opposite the sink area, you have room for a 30" square 2-person table with chairs right there. If you want a table for more people it should move into the living room, because dining tables start at about 36" wide by 60" long, although you can find drop-leaf tables that take up slightly less room. There might also be space for storage across from the range. Wire shelving is great for pantry items, freeing up counter space and allowing more cabinet space for dishware and cookware.

Do you have any reccomendafions for what I could use to add more counter space
