i've just femoved an old gas fire and 70s concrete surround and exposed an old back boiler which i want to remove so i can brick up the inside creating an alcove. but i,ve noticed there is no lintel above fire place and the two centre bricks have fallen out when i removed fire place.
i basicly want to know if this is normal or there should be somthing in there holding up bricks above?
It certainly doesn't sound like a lintel. I'm afraid I don't know enough to advise you on wether you need to install a lintel. It may be that your best bet is to get a structural engineer to take a look at it.
