KV fire department crews got the call about 2:30 on Sunday morning of the blaze at 16 Devonshire Crescnent.
Deputy Fire Chief Dan McCoy tells CHSJ News the cause is not suspicious.
McCoy says a lot of resources were needed to battle the blaze and Police helped evacuate nearby homes as a precaution.
He says in the years they have been fighting fires they haven't seen a house go up in flames so quickly and they can't at this time explain why.
