Building regs
I'm replacing a hearth and Building Regs Part J specify that the
constructional hearth has to have a depth of 500mm from the fireplace.
Unfortunately there is a wooden joist 460mm from the fireplace. If I
was to comply with the regs I would have to remove this part of the
joist. It all seems a bit much for 40mm. What are the consquences of
breaching the regs?
Does "Constructional hearth" mean something different than:
"the fireproof surface in front of the fireplace opening?
If not, why do you have to mess with the joist? can't
you just run over the top of it?
