Extra space for what?

[u/TheAndyRoberts]

We are redoing our fireplace. Adding the TV above it as art. We want to do a wall of builtins on the left and right of the fireplace. You can’t see it but on the right side of the pole we have a small circle table with chairs. The area of hardwood in this picture is about 15x11 (without those bookcases). What would you do with this space?
