The 44-year-old star was living in a rented property during the time the guest house at their main mansion was renovated.
It is believed that after the project was finished the actor moved back in with his family, reported AceShowbiz.
"At some point it just seemed illogical to keep living separately," a source said.
"He spends so much time in the main family home, the kids thought it was weird and they were asking lots of questions so both Jen and Ben thought it made sense for him to officially come home," the source added.
