I suppose that depends on the budget. You can get that look without custom.

Looking at all the idea people have shared I love the one you showed best it's open very spacious and clean

The others without the bookshelves make it look very cluttered a lot of dusting Much older look

The look you showed is definitely updated most current style of anything else that's up by far

HI -- Do something like the picture of the room with the long console . I dislike the other kinds because they look dated and cluttered.

You have nice opportunity to use all width of the room...from wall to wall . So if you can find something long enough to fill in space...if not then build in console.

I'd do a long low built in on the whole wall, or just get a simple cabinet under the TV and put some club chairs under the windows to create a conversation area. Either way, I would lower the TV just a bit so that it sits in the middle of the vertical distance of the windows.
