I haven't seen a wet bar in a living room in a long time. I think you should rethink the use of this space.

Sounds like a great idea, but instead of "wet bar" put in an espresso machine with the wine cooler. Place glass shelves for cups and wine glasses. Think the look will be super modern and sleek. Oh yea don't forget indirect lighting.

I disagree with the sentiment that you shouldn't do what you want to do. Go for it, enjoy your space as you want.
Have you contacted the millwork/kitchen shop that will actually build this for you? They will often include some amount of design service/guidance as part of their scope of work.

I don't believe anyone said that she shouldn't do what she wants to do. What I said was I thought it needed to be rethought, and what Terrance said was that he liked the idea.

Thanks for the comments guys. I've consulted my partner and we agree it only needs to be a "dry bar" no running water, sink, faucet required. Can someone give me feedback on the design. More specifically I'd like to know if there the placement of shelves as I've drawn it here is "old fashioned" as I want it to be modern and not a newly constructed design based on an older style. Thanks so much in advance.

I would include a wine cooler, probably not behind a cabinet door, and a refrigerator drawer. Glasses would be stored in a glass fronted cabinet. You could also add an ice maker if you're serving items that require ice.
I would not do wine storage with diagonal dividers as you have drawn. Square dividers seem to have taken over.

You should definitely ask the millwork company to do a drawing for you. It will gave thicknesses, returns, fillers etc and make the design much more real. Having them supply two or three versions is not unreasonable. You need to see this better before you decide. Even glass shelves have thickness and need a means of support....all of these will change the final look of the wall layout.

Love the comment re square wine bottle openings, less dated than diagonals. If you are serious about wine you need to modify layout to ensure you have enough bottle space - another thing you will gain by having true drawings done.

Are you thinking you want the entire back wall behind the glass shelves to be a slab of black marble??!?? Did I understand that correctly?

Would also locate fridge so it lines up below the upper unit that goes all the way down to the counter top and has the drawers (move to left) Make it feel more balanced, symmetrical and you can widen wine storage if need be.

Personally the hanging glasses seems.......meh, especially if in your living room.....I'd make it more about having a mix of shelves and cabinets so you can add some artwork mixed in with barware - again, less seventies bar in a living room look.
