Yes to the floor plan with dimensions.

As above. Every solid wall, every opening, every door, and every window has a dimension.

You can use graph paper, and be consistent with boxes on that paper and SCALE. - such as one box, 1/4 " equals ONE foot."

Yes to the floor plan and posted here in a comment in jpeg format. Right now that wall where that monster dated TV cabinet is should go for sure what a huge waste of space .

After the floor plan provide phots standing further back, and pick up / put away random items that clutter the existing view.

Difficult to figure out the room layout based on only your photos so yes to a floor plan of connecting rooms showing all dimensions.l

Yeah our house didn’t come with one so will make one 👍🏼

We await the floor plan. Include the contiguous rooms as well.

Based on your brainstorms above, remember when you knock down or open up a wall, you are diminishing space on both sides of that wall against which to hang cabinets, push furniture etc.

We purchased a beautiful apartment in which the previous owners removed a galley kitchen wall the year before we purchased it. They made a gorgeous open space. The first thing we did was rip out the new kitchen and add the galley wall back. It more than doubled our storage space.

Indicating load baring walls is necessary to know if demolition is being considered. Your pictures have no reference to each other. Are you saying the TV backs your cupboard wall? Pics with no dimensions are so deceiving right now I wonder why your kitchen did not extend into where you have the table. It appears a door was poorly placed.

Still waiting for the floor plan.

Here is the floor plan

If you want to extend the kitchen into some of the adjoining room(s), we need the floor plan of that as well.
