Homes left hanging on the edge of a Norfolk coastline following this month's tidal surge will be demolished by Christmas. Great Yarmouth Borough Council say four homes will be knocked down. The council say one of the homes was also found to contain asbestos.
The council say they hope to recover the costs of the work through Government schemes.
Thieves have stolen belongings salvaged from a home which fell into the sea after a tidal surge hit the east coast.
Three homes were destroyed and four others "seriously undermined" as waves ravaged the village of Hemsby in Norfolk on Thursday night.
But while residents formed human chains and battled to save whatever possessions they could as the homes slipped over the cliff edge, suspects made off with valuables which had been rescued.
Norfolk Police said the offenders struck at some point between 10pm on Thursday and 11.30am on Sunday.
A police spokesman said: "They entered the shed on The Marrams and removed a carrier bag of items that had been saved from a bungalow falling into the sea.
"Items taken include a gold necklace, three watches, a digital camera and a camcorder.
"There were many members of the public in the area offering assistance over the course of the weekend and officers would like to hear from anyone who may have seen any suspicious activity around the bungalow or adjacent sheds at the time of the incident."

"I think you can always do more, so here we are with a flood that was bigger than 1953, but with many fewer homes flooded - even though of course we built lots of homes in flood plains since then.
"So, I think the figure is had there been no flood defences you could have seen 800,000 homes flooded. So there's always more that can be done.
"There's always more flood defences that can be put in place, the funding is there but you can't always protect everything."
The Prime Minister has been paying a visit to North Norfolk this morning to see for himself the extent of last week's flood damage.
David Cameron visited Wells-next-the-Sea and spoke to residents whose properties were damaged in the tidal surge. He also thanked the emergency services for their work.
