I'll stick my neck out and toss my opinions in here to get this thread rolling.

On the wrap-around FP, any other openings in the same FP massing is too distracting for me. The FP glass is the moneyshot - it accentuates the horizontality, and anything above or below conflicts with that and distracts in an unappealing way.

On the backlit tv, yes it's cool looking but we are still in the early stages of an invention where you stick modern technology anywhere you can think of. The light seems to compete with the FP flame and if you are a pure media watcher it distracts from the screen as well. However, I would appreciate a backlit cove around either the entire FP mass or just along the sides, but not within the tv inset.

Just my opinion worth the price you paid for it.

I'll stick my neck out too. I agree with 3. The light is distracting, but subdued lighting is very attractive. I might do a fp with glass surround if it was the corner, not meeting a wall; open on both sides. For some reason with a wall it looks more like a fish tank. Now with 2 contents you'll likely get a whole slew of people who disagree. Just build what you like 👍

Thank you so much for your help and incite :)
It's a pretty big investment for us, so we just want to get it right the first time around.

Please post pic of finished project.

The glass sides wouldn’t be my first choice with the tv above.
