Arent&Pyke Soften a Federation Home in Mosman with Curves, Colour and Slow-Crafted Stone.

Full disclosure: this one’s personal. I’ve known Sarah-Jane and Juliette for longer than they’ve been a practice. I’ve watched Arent&Pyke take shape from the very beginning, and my admiration has only deepened since.

Few Australian studios have built a business as quietly assured. What Juliette Arent and Sarah-Jane Pyke established in 2007 has grown into one of the country’s most celebrated names in emotive interior design—and the generosity that runs through its projects is the same generosity that built the business. It’s all connected: the warmth, the layering, the conviction that a space exists to enrich the lives unfolding inside it.

Tucked into a harbourside pocket of Mosman, Bradleys Head House is a clear expression of that ethos. A Federation Arts and Crafts residence recast for a new generation, the home was extended across three levels by TKD Architects, with Arent&Pyke advising on layout, determining every surface finish and joinery element, then layering the furnishings that give the place its soul. One of the homeowners grew up here, so the brief was a balancing act—preserve the home’s stories while adding your own.

Arent&Pyke's Golden Light Proves That Great Colour Is Never Just Decoration.

At the centre of this Sydney home sits a chromatic palette of extraordinary depth—marigold, forest green, dusty mauve—that gives each room its own distinct emotional register.

Colour is, of course, an Arent&Pyke signature, and the living areas are where it sings. A symphony of terracotta, antique rose, light turquoise and pale sky blue moves across walls, joinery and stone, yet never tips into excess. The result is vibrant and richly layered while staying calm—exuberance held on a gentle leash. The deep terracotta of the loggia-like dining terrace deliberately echoes the home’s external red brickwork, dissolving the line between inside and garden.

The studio’s cleverest move, though, is softness. To marry old with new, Arent&Pyke introduced sweeping curves that nod to the home’s existing arched entrances. The most commanding is the kitchen island, its convex base carved from Pink and Rose White Tiberio marble, relieved by a bronze kicker and iced with a feathered sweep of Calacatta Vagili. Arches recur like a refrain—framing a freestanding oval bath in the parents’ retreat, repeating as an inverted woven-raffia pattern across dressing-room wardrobes, and inlaid as a tumbled Carrara mosaic underfoot in the powder room.

It’s the slow-crafted detailing that rewards a second look. Taking cues from the white timber shingles cladding the original verandas, the team layered intricate texture into the bathrooms—finger tiles rippling between fine brass ribbons, reeded glass filtering light through arched doors, and vertically scribed stone hand-chipped to catch shadow. In the powder room, a Turquoise Green granite pedestal rises straight from a mosaic floor, its accordion bands softened entirely by hand.

Threaded through it all is Arent&Pyke’s deft curatorial eye—vintage Scarpa Monk chairs, a Le Corbusier Lampe de Marseille, an Apparatus Cloud pendant hovering above the music room, mid-century finds mingling easily with contemporary pieces like the generous Lowell sofa by Hessentia.

What lingers is balance: heritage and modern are held in confident equilibrium, soaring period proportions grounded by warmth and gentle light. It’s the kind of home that feels properly lived in—generous, layered and without pretence. Which, when you think about it, is the whole Arent&Pyke story in one address.
