Can't you just use cabinet doors?

If it’s only 22” deep, not much of a walk-in. But 7’ wide is a lot of space to cover with door. If you put french doors, is there enough clearance in front to open the doors.
Alternatively, can you just use the existing buffet and cabinets as your pantry. Use the counter space to store/display the prettier pantry stuff (fruits/vegetables, anything you can/will put into pretty jars).
Or you can put all the small appliances out on the counter and see if you can get appliance garage doors for that area.
If you are thinking of remodeling the kitchen later, and not ready to choose cabinet doors and maybe try working with what you have?

I am guessing you meant a reach in pantry and not a walk in pantry. Can you take some pictures of what you are replacing and the rest of the kitchen and show a floor plan of the kitchen with dimensions so we can get a better idea of what you are trying to accomplish?

It's a reach in pantry. Or several. . Frame it in to 3 sepatate at 24 x 80 inch and use regular doors. . I assume you need walking clearance in front of it.

Far easier to organize food from small appliances and bulky pots, bowls..etc Don't forget the BACKS of the doors

Lisa, thank you for showing us what a real-life pantry looks like. Most pictures show a staged, sparsely stocked pantry.

LOL. Yea it is what it is.

lol It is what it need NOT be?

Don't put standard interior doors on your pantry as that would be extremely inconvenient and a waste of space. Use solid folding doors as you might use on a hallway linen closet

and/or use the tall base cabinet doors to create upper and lower doors -- don't try to make it literally a "walk in" pantry because the objective is increasing your storage space, not walking space.

Do leave any electrical outlets in the wall in place.

Construct a floor to ceiling wall on both sides of the width of space you have available for your pantry that are the same depth as the overall space you want to use for the pantry. With seven feet of width, you could begin buy building floor to ceiling shelving in the center of that space between the two new walls that are sized (width and height) for what you want to be most easily reachable -- such as for your largest countertop appliances that will be stored in your pantry.

With shelves, you can use trays or baskets or boxes as drawers for the shelves -- especially useful for the bottom shelves, to make it easier to reach what is in the back of the shelves at the bottom of the pantry.

Thanks for all the tips and ideas. Yes, you are all right.. it's a reach in pantry. I wasn't sure what to call it. Also, even though I am going to be updating the kitchen as a separate project, this is part of the update. It was suppose to all be done at once but the contractor is now having trouble getting people to forgo unemployment pay and come to work so he's had to adjust his scheduling and this is my priority. I like a lot of these ideas and will share with him. I found him here on Houzz btw.

I've attached some photos. Please disregard the bubble wrap on the corners. I have a blind dog.

There used to be a small corner pantry that would have been perfect but the original owner installed a full size Sub Zero wine fridge and closed off the rest of the space. I considered converting it back as I am a widow...who likes wine but I don't need to store 146 bottles !! Still, it's kind of fun to have and will be good resale in this retirement community. But I still need a pantry.

Jan what do you mean?

If I knew when they were building it I would have made the walls where the door hinges are longer so I’d have deeper side shelves when the doors open. This would have lent itself to a little more wall space on either sides and less door—

Stephanie, have you done this project? I have almost the exact same situation and pantry goal. I would love to see pictures of what you decided on.

I'd build some very simple shelving (there are a lot of tutorials to be found) and bifold doors that match the style of your other doors. This would be the most cost effective. If you are willing to spend more, I'd do some pullout options maybe. Analyze what you are going to store and try to plan accordingly. :-)
