Embarking on making our fireplace larger - both wider and taller. Read a lot of post and feeling fairly comfortable about extending the opening from 550 to 1000mm with a prestressed concrete lintel. Have taken further plaster away to see if there is an upper lintel above the brick arch over the opening. Have found a couple of coke blocks on side in amongst the block Are these likely to be related the the lintel that I'm looking for?
Thanks
