No date has been set to demolish the former home of Josef Fritzl in the northern Austrian town of Amstetten, the BBC reported.
Fritzl, 74, was jailed for life in March 2009. He was convicted of murdering one of his children through neglect, as well as incest, rape and enslaving his daughter.
The town's mayor wants the home demolished during the night, to deter media attention.
Fritzl's daughter, now in her 40s, and her children have received counseling, but details about their situation have not been made public.
