Just starting on re-installing a victorian fireplace (will be a working fire) and started pulling plaster off. There was a gas fire fitted sometime in the 60's I guess. The original hole has been built up with breize blocks & I was expecting to find a lintel of some sort, or a brick arch, above however it just seems to be the row of bricks without any real support apart from the breize blocks. Whats the next step? please see pics in my album (sorry I cant work out how to upload to this post)
