In addition to my post above...having lived with a fire set in a wall for many years with a vent to let the hot air into the room...I'd do neither of the above....except maybe old cabinets of well seasoned timber and not new built ins up against the wall enclosing the chimney. The heat from that fire and from the vent would affect the cabinets, dry them out, make them crack...especially since timbers today are not well seasoned as when the fire place was built....That enclosed chimney/flue would radiate heat as well...There's a reason why the walls each side as well as the timber shelves are a dark colour and there's nothing built into the spaces on either side. Installing the cabinets and painting them a pretty light colour might look good for a while but not if you intend on making good use of that lovely fire place. I've lived in my current 1900s house for 32 years and have come to know the why's and wherefore's about timbers and heat in old homes. One longs for a lighter environment sometimes but this needs to come from other sources rather than anything against the fire place. Its a bit of a blocker to renovations at times but again, with Wuff, "Embrace what you have"...read up about homes of the same period, surf the net...you'll find some beautiful solutions. Here's one....you could clad the walls either side of the fireplace with a fireproof stone cladding...enlarge on that...may not be your 'cup of tea' but for what its worth in making your place "yours".

strip part of the brick and mantle back to orignial if the exposed colour lines up with the room, strip the whole thing. Looks so well crafted not to pay respect to the past

I love the timber panelling, maybe with a bit of a clean it will look a bit lighter, but in any case, I love it! I actually think some lighter flooring would make the room work better - not what you were asking about I know! The current flooring being dark and matte sucks a lot of the light out of the room and also makes the timber panelling/fireplace feel heavier. Even a lighter rug (or even a fun Ikea Stockholm rug?) could make it look more crisp, fresh and stylish, whilst still giving a nod to your home's gorgeous retro features. A fresher light fitting - maybe a simple drum style?) would make it look more modern also and less busy to allow the original features to be the focus. Your existing armchair etc suit it beautifully though! The fireplace I'm not sure about - I hate to ruin original features but I'm not sure about that?! Maybe wiht the other changes done it might work much better anyway? Otherwise an interesting tile or sandstone cladding could work beautifully with the timber tones?

Has anyone here used country ledge stone in Ashfall for a fireplace? It is the stone that we picked, but I am second guessing my decision. I am having a hard time finding any pictures of it used. The two that I have found look different than what my sample is. I am also having a hard time trying to decide mortar color - go light or color that will blend? My plan was to have the stones placed a little further apart than what most do.
