If a designer has barely a month after signing onto a project to begin finalizing its fixtures, finishes, and fittings, she better hope she finds herself fully dialed into her clients’ aesthetic aspirations from the get-go. Lucky for London’s Tiffany Duggan, of Studio Duggan, that proved just the case with a creative, art-collecting couple whose four-story Victorian row house she recently completed in Notting Hill.“They’ve got great taste, great style,” says Duggan of the homeowners, parents to three children. What they didn’t have, however, was time to spare: Their new home was well into its top-to-bottom renovation—with the build team, Pembridge Developments, more than ready for final design decisions—when Duggan joined the project. And that’s why it proved a very good thing, indeed: “We were really well aligned from a style perspective and what we both liked,” the designer explains. “That made the process quicker.”Like many spaces in the house, the living room combines rich pink with paler green tones. Here, Edward Bulmer’s Celadon paint color adorns the walls, while a sofa from Duggan’s Trove lifestyle and home collection wears a Pollack red-pink velvet, and the fireplace fender a Schumacher ikat in similar hues. The clients brought with them the graphic cut-pile wool carpet as well as the art collection, which here includes a woodcut by Tom Hammick over an antique mantel from Lassco. To the right hangs a family portrait. Their simpatico sensibilities extended from a shared love of color to a mutual belief that any interior benefits from a mix of old and new. The clients wanted the decor to feel collected, “very much like it had been growing over time,” the designer continues, explaining this was relatively easy to achieve because the homeowners already had collections of antique and vintage pieces plus extensive art holdings. Perhaps the most important aspect of the alignment between Duggan and her clients? “They wanted to do something fun and interesting,” she says.So that’s exactly what Duggan did, beginning, of all places, with the children’s bathroom on the top floor, for which she paired zellige tiles in a soft lilac hue with a sink, tub, and toilet from the Water Monopoly, all in a buttery yellow. “We wouldn’t normally start with the bathroom,” Duggan admits, “but since we were tight on time, we focused on things we had to for the build.”
