The Block Australia winners Dea and Darren Jolly - may end up losers if a Melbourne council has its way.
The couple must rebuild the original frontage of a heritage home they bowled over, and could face a maximum fine of $190,000.
Former ex-AFL player Darren and his wife Dea have been contestants on The Block Australia twice, breaking records in April to take home almost $1 million.
Now Boroondara council are taking the couple to court for illegally knocking down a Californian bungalow, angering local residents in the process.
They purchased the problem property in the Melbourne suburb of East Kew, in mid 2015.
