Diane Keaton "can't stop" looking for a home.
The 69-year-old actress has renovated at least 12 houses over the past 25 years in her quest to find the perfect base.
She admitted: "I've always been looking for home.
"I feel like I've chased the concept of home with all the renovations and building I've done in my life, and I can't stop. I can't seem to stop having the dream of it."
The 'Annie Hall' actress - who is a single parent to adopted children Dexter, 20, and 15-year-old Duke - admits her mother's death had a profound effect on her and changed her outlook on life.
She told AARP The Magazine: "When I think about my life now, I try to be in the moment, cherish people I love and not be in pursuit of some abstract concept."
And getting older has also awakened a "magical aspect" of life for Diane and she thinks things are more interesting than ever.
She explained: "In a way, this is the most interesting time.
"At this age, everything seems much more astonishing. Like, 'Oh my goodness, look at that sycamore tree! Why didn't I see that before?' There's a magical aspect, a wonder to being on this planet."
