Hanna Weg stitched together three photos to create this image of the house before the remodel. She bought the two-bedroom hillside house 12 years ago, before she and Gill met and married. She was drawn to it because it felt like a treehouse in the sky, came with a pool and had a separate space below the living quarters that could serve as her office. But the architecture was all wrong. "Midcentury modern is in my DNA," says Weg, screenwriter of "The Beautiful and the Damned," an upcoming film starring Keira Knightley that's based on the F. Scott Fitzgerald novel. Weg grew up with Eames furnishings purchased for the Altadena home that her mother and graphic designer Saul Bass commissioned in 1958 — Case Study House No. 20, designed by Buff, Straub & Hensman — before they divorced. Gill, a self-described "recovering studio executive" and co-founder of the production company the Film Department, had refurbished four traditional homes in Hancock Park. But after visiting landmarks designed by Richard Neutra, he became a fan of the L.A. modernist's clean lines. Like Weg, Gill began dreaming of life in a light-filled modern house that embraced the outdoors.
