Custom. Mine are the same. I have 7 cabinets all in an attached row /not 7 boxes with duplicate side pieces between them.

I've seen the term "ganged" used for inset cabinets that are built as one unit rather than individual cabinets. Not sure if that applies in your case.

That would be site built.

I'm trying to research if I can modify/retrofit them or cut them down to fit a different layout of the kitchen.

Not sure what you are expecting from a google search, but the cabinets are just pieces of wood and other materials. So yes, they may be modified, just like most any cabinet.

Cabinets built in sections are often built in a shop, not only site built.

Shure you can modify your cabinets. Disassemble,layout and cut parts to size for modified cabinet, reassemble,touch-up finish and put modified cabinet in preferred location. If you are inlarging/extending cabinets you will likly have to buy additional wood but the buying is much easier than the using.

Thanks for all the responses. PPF, I'm a novice diyer and YouTube/google has held my hand on projects and I was hoping to find more how-to's so I can reconfigure my kitchen without buying all new cabinets. I don't want to ruin my cabinets and was hoping to find more people who have done what I want to do.

Eam44, no I don't believe I have what you're talking about. I'm glad you were able to modify yours! I love when you're able to work with a vintage kitchen !

Thanks Sally - I should say, that’s not my kitchen above. Mine was a 1970s brown kitchen in my old beach cottage in CT. I re-worked those cabinets till they were awesome. I miss that house every day ☺️ Good luck with your project!

I think Utube and Google have fizzled out. I've searched and searched for instructions on playing violin,dancing the Watusi and painting portraits without any success. Every one wants me to spend a bunch of time apprenticing and practicing but I'd rather play golf my days off and only do a little bit of dancing,fiddling and painting now and then.

Your cabinets have face frames? Rearranging them is probably a no go but modifying a specific section of the cabinet to say put in a dishwasher could possibly be done. Taking off the counter would show you clearly what you have to work with. I'm guessing there will only be 1 piece of mdf/plywood between each section. Hence you can't cut them in to separate boxes since you'll be missing sides. On top of that you'd have to cut the face frame. Which, if separating the boxes was feasible, you'd want to build new face frames.

The other thing that may be working against you in moving them around is the toe kick. Used to be made separately so it was put on the floor and then the cabinet run (? lets go with that term I guess) on top. I'm not sure how you'd be able to tell if yours are like this or not.

I don't blame you for not wanting to buy new cabinets but this may be waaay more trouble than it'd be worth in the end.

If you still wanna try I'd pivot and check out the tech or junior Colleges in your area. The one near me has a cabinet building class. I had a neighbor that made her kitchen cabinets through it and I and made a built-in China hutch for my last home. It'd be designed exactly how you want, with an instructor on hand, and all the perty wood working tools you'll ever need.

"for example cut the small refrigerator upper cabinet part off of the 27 inch upper cabinet it's attached to to instead build a refrigerator surround"

I read that three times and I admit that I don't understand it. Maybe some photos would help.

Wdccruise, this is all one piece. I want to remove the little cabinet above the refrigerator space but keep the 27 inch cabinet next to it. Then id like to build a refrigerator surround with a deeper cabinet above.

Some random thoughts.

Do you have help? That section of cabinets probably should come off the wall.

Do you have the tools needed, and know how to use them?

Do you have experience with finishing (stain and topcoat) and the ability to match what's there now?

Do you have a source for the crown molding?

Do you have room? Difficult to tell how close the cabinet is to the door trim.

What about the countertop and backsplash?

How is the face frame put together? Pocket hole screws were used by many shops and make disassembling the face frame easy.

Cabinets are not normally built with disassembly in mind, so it helps to know how they might go together to make taking them apart easier.

From the picture it looks straightforward to do what you describe. As for term you can google to find instructions, I doubt instructions exist for your specific cabinet.
