Sharon Osbourne described Ozzy's final resting place as her "little piece of heaven" before his death.
The 72-year-old star's late husband died of heart failure aged 76 at their Buckinghamshire home on July 22, and he's been buried on the grounds of Welders House 32 years after they bought the Grade II listed property.
Upcoming BBC One documentary Sharon and Ozzy Osbourne: Coming Home will explore the last three years of the Black Sabbath legend's life as the couple returned to England after three decades in Los Angeles.
In the film, she says: "It was just like I could breathe. It's our little piece of heaven.
"All you hear are birds, little bit of our dogs barking, Ozzy screaming."
In the film, she reveals it was the heavy metal icon's decision to make the move away from the United States.
She adds: "It is Ozzy's decision whether he wants to spend the rest of his life there or here.
"Home is where both of us are. As long as he is with me I am alright."
The documentary - which will air on the BBC this evening (02.10.25) - follows the final three years of Ozzy's life as he prepares for the move back home.
The rock star himself says: "We're so used to running after the kids we don't know what it is like to be with ourselves and to be with each other.
"I can't wait until I am there."
Elsewhere in the documentary, fans will see Sharon opening up on how the couple planned to retire from public life once Ozzy turned 70.
She says: "I always always told Ozzy, when you're 70, we say goodbye."
The former X Factor judge recently spoke out for the first time since her beloved husband passed away as she thanked fans for the "comfort" their messages of condolence have brought to her.
She wrote on Instagram: “I’m still having trouble finding the words to express how grateful I am for the overwhelming love and support you’ve shown on social media.
“Your comments, posts, and tributes have brought me more comfort than you know. None of it has gone unnoticed, in fact, it’s carried me through many nights.”
