When Greg Natale got the call for a new project in Melbourne, the Australia–based interior designer was on a research trip to Paris. Surrounded by the magic of the City of Light—so many arches and swaths of maroon—inspiration was not difficult to come by. The owners of the residence, who run a luxury watch and jewelry business, fittingly requested the lavish use of jewel tones—particularly pink and maroon—after seeing the latter’s rich application on the walls of Natale’s own apartment.

The brief for the 4,000-square-foot penthouse apartment in the elite Melbourne suburb of Toorak included bringing a sense of grandeur to an otherwise uninspiring minimalist shell. The sprawling space started as a spec apartment, so it presented an incredibly clean slate. “But that also meant it was neutral. My clients aren’t neutral people,” Natale says. “They’re a young couple, and they’re open to a lot of new ideas.”

Taking the owners’ love of rich and varied hues, and the beautiful gleam of brass, Natale began a process of luxe layering and embellishing over the original space. New elements included a dramatic mirrored entry, a series of arches to form different spaces, and the additions of a fireplace, joinery, kitchen benchtops, bathroom vanities, finishes, and furnishings throughout. Blush-painted ceilings make for an intimate setting while picking up the slight pink tones of the light oak floors. On the walls, fluted white lacquer panelling adds luxurious detail and evokes the spirit of ‘80s-era *Dynasty–*style glamour.

Pink comes into its own in the dining room, which features Gucci Heron wallpaper , and creates a delicate cocooning effect in the wallpaper of the guest bedroom and in the lacquered joinery and pink marble wallpaper of the dressing room. “My favorite is the dining room. The Gucci wallpaper is so elegant, but it’s also useful,” Natale says. He admits that pink is easily his favorite color, too. In the bathroom vanities, kitchen benchtops, and backsplashes—and with the living room fireplace—pink tones come courtesy of the striking materiality of Calacatta Viola marble. Maroon enriches the palette with lacquered joinery in the kitchen and lacquered fluting in the living room and primary bedroom. “The millwork relates to the owners’ jewelry business too. The same builder in their home also did their shops,” Natale says.

Maroon patterned wallpaper brings with it a luxurious feel to the powder room. In the primary suite a lacquered maroon door opens to reveal a change of pace thanks to black, gray, and white mosaic tiles from Bisazza laid in a chain link pattern. Accidentally, it makes for a playful reference to the owners’ business.

Beyond the shared affinity in terms of tones, the clients were also keen on finding a designer who could easily incorporate their already existing Jonathan Adler furniture into their new space. So, with a foreword written by Adler in Natale’s book, The Tailored Interior , it was another obvious match. “Jonathan likes when I reupholster and reinvent his work,” Natale says. He introduced a mix of vintage and contemporary pieces to work with the existing Jonathan Adler furniture.

The final element to the design was establishing a grand sense of entry, which Natale expressed by creating a hall of mirrored panels and arches. With sculptural Kelly Wearstler lights and a pink-and-gray postmodern Art Deco rug beneath the gray textured wallpaper on the ceiling, the effect is mesmerizing and suitably sultry at once. The end result strongly relays the love of luxury and glamour—for the owners and for Natale.

Inside the home.

In the dining room, Jonathan Adler chairs in different shades of pink velvet sit around a brass Boca do Lobo table under a vintage pendant light. A Greg Natale rug is another foundational element to the scene.

Brass and marble accents find their way into nearly every corner of the apartment.

In the sitting room, reupholstered sofas bring a fresh modern print to the space. A luxe clear acrylic coffee table by Jonathan Adler with brushed brass accents sits beneath a vintage pendant.

In the living room, a pink quartz Christopher Boots pendant hangs above a maroon Minotti sofa and blush Jonathan Adler chairs.

The veins of color in the marble play off the fluted maroon walls, which create a warm and character-filled mood.

Arches of varying widths—a callback to that trip to Paris—were added throughout as a way of breaking up the open-plan interior and creating moments of drama and interest. Lined in plated brass, which speaks to the owners’ fondness for the metal, the arches also serve as a way of shifting between different spaces in the home. The Laine Suspension lamp over the island is from Delightfull.

The bold Calacatta Viola marble sink is nestled in a richly patterned-cloaked powder room.

In the bedroom, a spectacular sculpted Oly canopy bed in antiqued gold adds the final touch of grandeur to the moody maroon-hued space. The Art Deco–style rugs, which are an essential piece of Natale’s business, are used throughout the interior to add vibrant patterns to the apartment’s unique energy.

“I love a chain link,” Natale says. Entering from the lacquered maroon door, the primary ensuite reveals a much less colorful room, but still a sense of drama with Bisazza tiles laid in a chain link pattern.

The panels of brass-lined mirrors create a dramatic moment for a walk-in closet.

This project will appear in Natale’s latest book, The Layered Interior , which is slated to be released later this year. The Norah Suspension lamp over the guest bed is from Delightfull.
