Depth of Chimney breast

[Yellowduck]

Hi,

I have a 1950's bungalow with an external chimney breast (not party wall) that extends into the room by about 15 inches. Can anyone give me an idea how far back from the front of the chimney bresat the flu runs?

The reason is I want to create a 3'' recess, 3' x 4' in the breast for a flat screen TV, and preferably do not want to damage the internal flu (the fireplace will have an open gas fire installed, it will not be an open coal/log fire).

Thanks

I am sorry to say that creating a recess in the chimney breast is a non-starter unless you never want to use the flue again.

The actual flue is probably around 4" in from the face of the wall. There are minimum thickness's of non-combustible material required all around the Flue, so you see any recess forming is going to impact on that.

As above; if the breast extends into the room by about 15" (could it be just a little less?), then it is more than likely the front will only be a single-thickness of brick, which precludes hacking any of it away.
