After seeing your before/after photos in your [kitchen thread[(https://www.houzz.com.au/discussions/kitchen-reno-ideas-suggestions-please-dsvw-vd~3651370?n=11) I thought I'd bump this thread. I have a better idea of the whole space now. Have you had any more ideas of what to do? I think by cladding the whole surround and wall above could have big impact and modernise so it ties in with your new kitchen. Also give some balance as it sits alongside the glossy black bench. If you like the warm of timber, you could clad running the wood horizontally. This final photo is cataloged as a transitional look but same idea with cladding all the way up. ETA: That artwork would look great on a dark grey backdrop.

Looks so cosy! Stone fireplaces are the best :) Well done

It is difficult to give suggestions as we cannot see the space you have. However, I like the idea of a pop-up flat screen. This would mean that the TV doesn't become the feature in the room. Alternately - You could have a wall unit built where the TV is hidden behind doors. If you have the room, have matching cabinetry on either side of the fire-place.

By viable I mean workable, functional. A chimney sweep or a builder adept in chimneys will give you a report. Certainly enquire about a future gas fitting rather than logs if possible. I say this as a fireplace anywhere is delightful and, if downstairs, it could heat upstairs through the house, to a certain point too. If you look at the quality of the brick laying, you will see that its not meant to be a feature which is why it was rendered, but that is choice only. Certainly seal the bricks. Good luck and stay with it if you can. Everybody loves the romance of a fire.
