But that trope is what architect and designer Andreas Martin-Lf and his client, fashion journalist Sofi Fahrman, were trying to avoid when designing the 4,800-square-foot Stockholm flat for her and her husband, businessman Filip Engelbert. Our mood board was very Parisian, says Fahrman. For Martin-Lf, however, his primary mission was embracing the buildings past. In Sweden, people are a little bit afraid of things that look old, he says. But my architecture relates to both a buildings history and its future.The architect Andreas Martin-Lf and Sofi Fahrman, a fashion journalist.The property, originally built in 1917, possessed no shortage of historical intrigue. It was once home to Ivar Kreuger, the disgraced matchstick mogul known as the Leonardo of Larcenists for his Ponzi scheme business dealings. Unfortunately for Fahrman and Engelbert, their unit, located directly below Kreugers one-time abode, had been marred by a gut renovation in the 2000s, which had stripped out most of the original details. But a fortuitous meeting with the elderly current tenant of Kreugers former apartment allowed them to understand precisely what was missing. I went there with my measuring tape, Martin-Lf recalls of his visit to the domestic time capsule, which he describes as Rothschild-style for its dark-stained wood-paneled walls, carved door frames, and grand staircase reminiscent of those in Gilded Age Manhattan mansions.Such drama may seem like a far cry from Martin-Lfs workthe Swedish architect is best known for his minimalist houses wrought in noble materials and luxe custom yachtsbut his skills lie in an innate ability to gracefully layer styles and eras. For instance, in the living room, sheer curtains flood the cream-colored room with light, bouncing off a pair of amoeba-shaped brass coffee tables and a spiral Murano glass chandelier. A custom curving sofa upholstered with Pierre Frey velvet echoes the shape of the rounded bay windows and is balanced by two cross-hatched Croisillon armchairs by Jean Royre and a vintage Italian sideboard. In the sprawling primary suite, the dark-stained boiserie recalls the homes original wooden paneling, while on the walls and ceiling, cornices and carved door frames create texture. The patterns are based on ones I found upstairs, Martin-Lf says. We brought the house to life by having a strong connection to its history.While much of the kitchen echoes the white and gray hues of the marble countertops, including the dove gray cabinets and white pendant lamps by Apparatus, it is the caramel-hued woodin the form of oak parquet floors, Pierre Jeanneret dining chairs, and stained oak bistro tables by Hanna Wessmanthat really adds a sense of warmth to the space. An abstract glass sculpture by Rina Eide Lvaasen sits on a plinth by the window.In the kitchen, the designer even recreated the original marquetry wood floor, though there were also structural reasons for ripping up and replacing the parquet. The solid marble countertopa heavily veined white stone from Portugal that matches the dove gray cabinetsrequired Martin-Lf to install reinforcements to support its weight. (A similar procedure was required to accommodate the capacious freestanding marble tub in wood-lined the primary ensuite.)For Fahrman, it was important to get the kitchen just right. She and Engelbert have a large, blended family, and they wanted to make sure there was space to keep everyone close. Filip has three kids, I have a daughter, and we have one son together, she explains. On weeknights, between the kitchen island and built-in benches with scalloped-edge tables by Hanna Wessman, there is room for everyone to pull up a chair. But for holidayswhen both of their extended families are overthey needed to get creative to fit everyone in at once. In the dining room, a grand salon with a custom bar cabinet, pendant lights from Apparatus, and hand-painted de Gournay wall covering depicting climbing vines and perched birds, their solution was to eschew a single long table in favor of a series of small ones. The circular pedestal tables, complete with cozy loveseats and wire chairs by Warren Platner, are scattered around the room like a Parisian bistro. Its quite Swedish, you know, reflects Martin-Lf on the decision. Were not super formal people.1/13Maria Miesenbergers sculpture, Leap of Faith, basks in the sun in front of the living room window.2/13Soft curves and luxe materials set the tone in the living room, where a custom sofa upholstered with velvet Pierre Frey fabric dialogues with a pair of bespoke tables in brass and a vintage Murano glass chandelier.3/13Martin-Lf layered contemporary and vintage pieces in the peaceful, light-filled living room. That included custom furniture like a softly curving sofa, amoeba-shaped brass coffee tables, and spotlights from his own lighting brand, Untitledas well as impressive auction finds like a pair of Croisillon armchairs by French master Jean Royre, a vintage Italian sideboard, and a spiral Murano glass chandelier.4/13Martin-Lf was forced to rip up the kitchen floors to install reinforcements able to support the massive Estremoz marble countertops.5/13One of my best friends, Hanna Wessman, makes amazing bespoke furniture, says Fahrman. I love knowing that she made these tables in our kitchen.

But we also wanted them to be fun. A custom bunk bed, set inside an arched casing, is flanked by two floor-to-ceiling shelves holding books and toys.
