Demolition work has begun in Hemsby to tear down five homes at risk of falling off the cliffs and into the sea.
They are among 13 properties evacuated last weekend after strong winds and high tides eroded the cliffs.
Great Yarmouth Borough Council says the work should be finished before Easter weekend.
The other properties are being closely monitored by the council.
The diggers moved in this morning as Great Yarmouth MP Brandon Lewis was surveying the damage.
He'd been criticised for not visiting sooner, but now he says progress is being made towards a plan for new sea defences.
Next week, more than 100 lorries of sand will be moved from North Beach at Great Yarmouth and taken to Hemsby.
It will be used to fill the gap between the beach and the lifeboat shed so the sloping ramp into the beach can be kept.
People are being reminded that the beach below the cliffs is dangerous and should be avoided.
The cost of the demolition will be discussed with insurance companies.
