Great design can be reinvented. The evidence unfolds like poetry at Beverly Grove—a new residential creation from Shelly and Avi Osadon, the husband and wife duo behind SEE Materials and SEE Construction. The 11,255 square-foot residence’s museum-quality details and unparalleled hillside perch, just five minutes from the Beverly Hills Hotel, say nothing of its architectural past. Yet somehow, they say everything.

A landmark 1947 Case Study House by Rodney Walker had once resided on the same site. Like all the Case Study Houses, it was a bold experiment—a modernist’s dream for how families should live (or in Walker’s case, his own family). The No. 16 house had fallen into disrepair decades later, and was eventually demolished to make way for another dream: a custom contemporary for a married couple. During the planning phase, however, the husband had suddenly passed away. The wife kept the property for years, not ready to let it go, says Osadon.

“She had no interest in selling the property initially,” recalls the designer. “I gently convinced her that even though we wouldn’t be building their dream home, a dream home would definitely rest on this incredible site.”

Five years later, Osadon made good on her promise. Her vision of a dream home? A world-class boutique hotel.

“We wanted to include every amenity, so that when one enters the home, they really have no other place they would rather be,” she says. “There are so many different places to entertain guests. And at the same time, you feel like you are at the highest-end resort.”

You get the resort feeling from the moment you enter the main level living area—voluminous, open and flowing with materials that inspire you to move seamlessly from indoors to outdoors without one step or change in elevation. The powder room is a statement in itself with its angled mirror and floating sink design. The dining room table and living room areas are illuminated by Osadon’s custom glass tube chandeliers, while a custom leather wall commands attention in the family room.

On the lower level, you arrive at the entertainment and guest spaces—a theater room, climate-controlled wine room, two additional bedroom suites and a game area that features a window looking into the pool above. Upstairs, there’s a stunning 2,200-square foot master suite with equally stunning city views.

Moving outside, Osadon strategically placed an infinity-edged pool with a 12-person spa, fireplace and entertainment area. The partially submerged chaise lounges, reminiscent of a Greek island getaway, face the Pacific Ocean in the distance. These are just the kind of details that Osadon is known for.

She traveled to the far corners of the world to bring rare and oftentimes unexpected elements to the home. It shows in her restrained palette: Italian-imported engineered marble slabs measuring 5 x 10 feet on the floors, eye-catching Calacutta marble fireplace in the living room and metallic black pearl wallpaper lining the master bathroom for a mesmerizing, kaleidoscope effect.

“You can’t have a great design without great materials,” she says of her design philosophy. “I believe less is more. When you pick the right materials, you don’t need many of them to make the space feel unified. In fact, in this home, we used less than 10 different materials to outfit the entire home. The end result is such a cohesive and unique feeling.”

The engineered marble slabs, for example, not only create a visual impact, “since they had never before been used in a residential flooring setting,” she says, but they also create an amazing stage for the rest of the materials to stand out.

“They are a work of art in and of themselves,” she explains. “We worked with this material in a few different ways, by placing it on fireplace walls, creating a custom vanity and applying a leather finish to the stone, as well as designing a new edge detail that was extremely unique.”

Osadon is a master at mixing unexpected textures and artwork as well. For the leather wall in the family room, she selected untreated leather and cut them into tiles to apply to the wall. She also used the same material, treating it to a wash for a vintage look, and designed two chairs to sit along the leather wall. In the formal living room, there are two dramatic tufted sofas draped in black leather like “a beautiful dress,” discovered during a trip to Italy. She also personally curated the artwork in the house—most of it by fashion photographer Guiliano Bekor.

“Everything in this home is so special,” she says. “It makes you feel. It gives you an emotional reaction.”

With the reinvention of 9945 Beverly Grove complete, the residence has become the new benchmark by which Osadon judges all other projects—and the new benchmark by which one sophisticated buyer will judge all other dream homes.
