If the primary use will be tv I'd aim for comfort watching tv.

Remove the chairs, shelving and sofa table to start. Add a sofa with chaise opposite the tv and blocking the room behind you're using as an office. Ad a matching ottoman. With those and your existing sofa moved back a little, you have layout family space for tv watching. I like this piece from IKEA because it has removable washable covers and pocketed coil seat cushions at a fair price. Plus, storage.

Harlanda Link.

as a start, I would swap the sofa/sofa table and the two chairs.

move the small shelf unit to the right of the window

I would also add drapery panels to both sides of the window to soften.

Center that big unit on the wall.

...wondering what is on the wall you too the photo from?

Here’s a view of the other side of the room.

nice. I think I would swap out that big unit and those framed pieces, along with my other suggestions above. too clean up that trafiic flow.

Not sure if there is enough room to keep the console table behind the sofa.
