If you are going to the effort of retiling the fireplace surround, would you consider going to a bit more effort and creating a full wall unit which incorporates the fireplace and the TV, with extra shelves and cupboards to display and store? (I also have reservations about the heat and the TV and associated wiring.) This may also address the lack of symmetry associated with the location of the fireplace, if that is a consideration. Do you use the fireplace often enough to justify keeping it? Alternatively, a wall unit on the left hand wall, which is where the power and TV points seem to be, may be the best solution - as previously suggested. All the best.

I went to Photos>Outdoor>Decks and searched "barbecue" and found lots of them on wooden decks. Some were freestanding, but most of the built-ins seemed to be surrounded by fireproof material.

Depends on how you want to style it, but I think this would look lovely and make your room feel nice and cozy.
