How's the fireplace coming along? Can't wait to see the end product. What surrounds the flue above the stackstone? Do you have to build a hebel chimney or will this just be fire retardent plasterboard?
We are currently looking to do the same thing but I was under the impression that an inbuilt fire without a zero clearance box needs to go into a fully bricked fireplace/chimney. Is this right? It would be so much easier if we only need to do a hebel box around the fire.
