For anyone who wasn’t on Instagram and didn’t watch the extravaganza unfold in real time, the Italian fashion editor, creative director, and street-style star Giovanna Battaglia married Swedish real-estate developer Oscar Engelbert in an over-the-top celebration in Capri, Italy, this June. (Go down the rabbit hole: #gioandoscar.) There was a sunset ceremony—the bride, who grew up in Milan and has worked for such brands as Dolce & Gabbana and Carolina Herrera, wore an Alexander McQueen wedding dress with a 12-and-a-half-foot train—followed the next day by an all-night rager on a barge floating just beyond the island’s legendary Blue Grotto.

When the hangovers wore off, many wondered where the couple, famed for their fabulousness in the social swirls of New York and Paris, would swap their dancing shoes for bedroom slippers. Turns out the newlyweds had a trick up their sleeve: this elegant apartment in an 1800s building on Stockholm’s Djurgården island, where Oscar was raised. What’s the one word Giovanna uses to describe time there? “Quiet!”

In renovating the three-bedroom, four-bath flat, the couple was sensitive to the structure’s 19th-century roots. It was “a restrained, modern restoration,” Oscar says. “The home is 100 percent a reflection of what we like and what we collect. Every single piece has its history of where and when we bought it.”

The duo did not use an architect or designer, instead relying on Oscar’s visual savvy—he founded Oscar Properties in 2004 and has constructed modernist buildings around the world with such architects as Rem Koolhaas and Bjarke Ingels—and Giovanna’s personal style, heretofore mostly expressed in the fashion arena. Giovanna, a contributing fashion editor at W and a senior fashion editor for Japanese Vogue, explains, “All the knowledge I have came in handy, but you have to be more careful since you can’t pin a chair to make it look good the way you can with a skirt for a photo shoot.”

By their own admission, Oscar’s design approach is cleaner and more subdued, while Giovanna usually subscribes to the more-is-more ethos. “It’s been interesting to look at the evolution of my own aesthetic since I met Oscar,” Giovanna says. “I used to think Oscar’s taste was too cold or too minimal, but I got caught up in his enthusiasm and passion, and now I really like it.”

At the same time, Oscar has learned to appreciate Giovanna’s penchant for color, notably in the sunroom they call the veranda. “I wanted natural colors, and then Gio came home with velvets from Rubelli. It was out of my comfort zone, but when it sank in I loved the idea. Now it’s one of my favorite parts of the house.” He laughs as he says that his friends—many of whom teased the couple that collaborating on their house was a bad idea—are just as surprised by the results as he is. “Miraculously, we ended up agreeing on everything!”
