The formal identification of two people killed in an explosion at a bungalow is expected to take days.
They died after a series of blasts at the property in The Street in Lidgate, near Newmarket, Suffolk, at about 12:00 BST on Tuesday.
An investigation into the explosion will resume after a “safe entrance” to the property can be guaranteed, firefighters said.
Part of the building will be demolished before closer inspections can begin.
The cause of the explosion is not known, but it is thought to have been caused by a gas explosion, Suffolk Police said.
Officers added that while the deaths remain “unexplained”, they do not believe there is any “third party involvement”.
Steve Mableson, from Suffolk Fire and Rescue, said work by contractors would “render the property a lot safer than it is now”.
He did not specify what part of the bungalow presented a risk but said demolition work would provide a “safe entrance into the building”.
One neighbour said Tuesday’s blast rattled the windows of homes further along the road, and described it as a “huge explosion”.
Suffolk Fire and Rescue Service sent four crews to deal with the subsequent blaze.
