Consider a fold-down wall table if you don't find an L desk configured the way you prefer.

It seems a simple ask, but large desks like that are not common anymore. I had a beautiful, large cherry L desk for a very long time, when I moved here I tried to donate it and NO ONE would take it (HforH, Salvation Army, Good Will, consignment shop, etc). No one wants desks anymore, especially not big ones -- that's what they all told me. Take a look furniture stores -- that statement will bear itself out. Maybe you can find something on-line, IDK. So explore other options such as a regular desk with a separate folding table or a fold-down table, like mentioned above.

I Googled "L-shaped standing desk" and got a gazillion results back. You can raise and lower as needed.

There is something called a Lagun table that they use in RV's. It can be moved in many directions and can be raised and lowered and the top can be custom made to the size you need. Take a look and see if this would work for you.

Those standing desks aren't what I had in mind when I typed my reply - I was thinking traditional desk-desk.

ETA: What do you want in a desk, OP? To me, those links above and the standing desks rec brings up items I consider tables, not desks. I'm basing that comment on what *I* consider a desk to be and how it should function. But that may not be you -- so you need to think about how you need the whole shebang to function before narrowing down your choices.

I found this. Not a bad idea. It looks nice an I can take it out of the room to use when I entertain a few times a year. No holes needed in the wall!

porkchop_mxk3 z5b_MI I have 24" touch screen PC and a printer/fax machine I just got. I also need a file cabinet and drawers for supplies. Im trying to keep the window space to my left open so I can have a place for my cat to sit and be entertained.

@porkchop_z5b_MI unfortunately I need a deep desk because my new monitor/PC is quite large and I need distance. I understand what you mean though.

^^ Did you ever find anything that would work for you?
