The grandmother of six children who died in a house fire said they will be able to rest in peace now their former home is being demolished.
Vera Duffy, Mairead Philpott's mother, said she had wanted to see the start of the demolition process to end the tragic chapter in the family's history.
Derby City Council said the process of demolition is likely to take up to three weeks; one week to prepare the site and a further two weeks to take down both properties, beginning with the outbuildings and roofing structures.
New social housing is expected to be built on the site.
