I updated the surround of my fireplace 8 years ago but are going to be doing a whole house remodel this summer. Here is the current fireplace. Dimensions are six feet wood by six feet of fireplace by six feet of wood and then A five foot opening to the dining room.

Any ideas? This is the room we sit in all the time. It is 18’x23’ with wood walls, wood doors, or windows on every side. I could do a fireplace insert of about the same size and add rock for the entire six feet of the fireplace
Or I was thinking of taking out the chimney and creating a whole new look. Photos attached. Second photo show 30” bump out in dining room. All walls are walnut.
Floors are either going to be engineered French oak or a 2’x2’ natural stone. Graph paper is 1 sq. =1’
Option 1 is just add tv to right and three pictures to left
Option 2 is rock fireplace floor to ceiling add rock bench
And tv
Option three is Last photo, a whole new look see thru corner fireplace to dining room

Just not sure if the rock bench or see thru fireplace go with the walnut paneling and then how long to make them and where to put the tv.
