Further wall collapses are likely to happen following the second incident in four years on a Sheffield street, residents have warned.
Peter Coope, who lives in one of the affected properties on Armstead Road with wife Michelle and their two children, said a similar wall collapse had happened at his parents’ house on the same street four years ago.
“It is going to happen all the way down eventually,” he said.
He said he was concerned the latest collapse meant a large garage in one of the Orchard Lane properties is now only a few feet away from the gardens below.
“If that goes, somebody could get hurt,” he said.
Mr Coope’s parents Keith and Lyn still have rubble in their garden from where the boundary wall at the back of their property collapsed four years ago.
They are involved in a legal battle over who should be responsible for the costs of the clean-up, with a High Court hearing due later this year.
Mr Coope Snr said planning permission should not have been granted by Sheffield Council in the 1970s to extend the height of the walls at the back of the Armstead Road properties.
