Sometimes what appears to be a relatively straightforward renovation project turns up a few challenges that slow up or even stop the completion of a property makeover.
But with this property in Bargoed, Rhymney Valley that featured on BBC's Homes Under The Hammer it was a human based challenge that slowed up progress, an unresolved disagreement.
It meant that when the programme's production team returned to film the renovation project transformation two years after the first visit, the property still wasn't finished.
