On the 1888 ordnance survey map there is a smithy shown in tyberton, it seems to be still there on the modern map.
Assuming we mean the tyberton near Madley I have driven past it many times but never noticed a house there, I feel it may be hidden behind a hedge.
You should be able to find it on street view, it is on a very tight bend just after tyberton going towards Madley on the B 4352
