Shallow <12" deep cabinets under the tv only won't be a problem. You have a window in the dining segment. This could balance the tv somewhat for taller cabinets across both segments. You need to draw the wall with the window and tv. Then cut out some different cabinet pieces and see what looks good if anything.

@dan1888 thanks thats my main concern that it will look unblanced or like i didn finish across the wall and one side heavier. i wonder if i paint the dining side it would help

Extend it all the way across as a buffet in the dining, and media storage in the living. 15" deep cabinets will work for either.

I'm looking now at the overlap between your sofas. One end isn't usable. Maybe a sectional will avoid that.

Put cabinets on the long inside wall. You only need 12" deep to store dinnerware and glassware.

The table/chairs can be redesigned to accommodate any space issues.

I am looking at the plans with the table horizontally, and you have two more horizontal pieces in the living room...too much of the same visual. Either turn a table or get a round one.

Consider facing the sofas, so one sofa divides the space. Where the sofa is now, facing a tv/fireplace (?) add two chairs.

How far along are you?

You need to draw correctly scaled furniture and lay it out on the plan. I think you will find that you don't have as much room as the designer/architect drew on the plans. Design software programs always seem to have way undersized furniture which gives a false idea of what you can fit and how spacious the space will feel.

The sofas shown are 7' x 32" which will not fit 3 people comfortably and will be too shallow for comfortable TV lounging. The type of uncomfortable sofa you would find in a doctors waiting room.
