Sonia Kimotsuki and Alden Huen have called San Francisco’s Marina District home for close to 20 years. It’s been a backdrop to the big moments in their lives: buying a home, marriage, the birth of their son, Ethan. So when they decided to completely transform their three-unit building in 2014, it was another investment in the area that they’ve lived in and loved for decades.
After losing out on so many properties, they widened their search—but, as it turns out, their future home was just across the street. One day, as Huen was returning from a run in the neighborhood, he noticed a for-sale sign going up on a house diagonal to theirs, one that featured arched windows on the top floor, an elegantly curved entryway, and terra-cotta shingles. It was clearly not a two-bedroom condo, but they immediately called the selling agent to see it and made an offer before it even hit the market.
“It was a little risky, because it was a three-unit building,” Kimotsuki remembers. “We were kind of like, are we ready to be landlords? The whole idea was very scary at the time, but we did it and it ended up being really good.”
The purchase process was a whirlwind, not least because the couple happened to be getting married the same week. “We had family from all over the world traveling in and the timing could not have been worse,” she says. “There was a lot of trust put into the process. Sometimes that happens in a good way, right? You have to prioritize.”
In the 13 years between buying the building and renovating it, Kimotsuki and Huen split time between San Francisco and New York for six years, and also had Ethan, which meant more extended family was around the house. So when both rental units opened up at the same time, they took advantage of the vacancies to transform the building into a two-floor residence, opting to convert a small unit in the back into an apartment for rent.
Their initial thought was to combine the building’s middle and bottom units, but the more the couple thought about it, the more they realized that change wouldn’t add much space, and they enjoyed living on the top floor, which had been their apartment since the beginning. Instead, they fused the top two units, which were both two-bedrooms, and added a roof deck.
“Having Jay involved from day one was so important, because he didn’t just come in and do the design of an interior that he didn’t have any say in,” explains Kimotsuki. “He actually was part of the building process and figuring out with the architect the layout and our lifestyle, and incorporating how we wanted to live in the space.”
Jeffers enlisted senior designer Victoria Nady to work with him on the project, and describes the process of working with Apparatus as a joint design effort on everything from the staircase that leads up to the living space on the second floor to the look and flow of the kitchen, like a custom banquette that greets them at the top of the stairs.
He took cues from the home’s Art Deco-influenced curves and mixed them with jewel tones and a modern sensibility in the design and furnishings. “We knew the clients were fairly modern, we knew they wanted to be very comfortable,” Jeffers says. “They have a busy life, but they love being at home and having friends over.”
Instead of putting the living space on the first floor of the residence and bedrooms on the second, they inverted them for a more seamless flow onto the roof deck. To boot, the ample light from the top level’s arched windows fills those daytime-use rooms. The original layout of the home was more formal and segmented, but Kimotsuki and Huen wanted a casual, easygoing floorplan.
“When you come up to the top of the stairs, you’re basically in the kitchen,” Jeffers explains. “The back of the kitchen island is a banquette with a table and you would think that might be just their breakfast table, but that is their all-occasion dining.”
They divided the family room and kitchen with a section of cabinetry, allowing the kitchen to be more expansive without being closed off. The media room flows directly into a library—framed by a curved molding that plays off the arched windows—that houses the couple’s family book collections and desks.
The master bedroom is anchored by a row of windows and a floor-to-ceiling custom upholstered headboard. The bed is flanked by paneled walls with a hidden door into Huen’s closet, and nightstands were built into the walls to give a streamlined look. (Sonia’s closet is off the master bathroom.)
Kimotsuki and Huen gave Jeffers full freedom to execute his style, which made the project an exercise in creativity for him. The couple was thrilled with the end result, and were delighted that the design allows for their son to age without feeling stuck.
“He made it a space that Ethan was going to be able to grow in and it wasn’t going to be outdated from day one,” Kimotsuki says.
Huen loves how much warmth the home now exudes.
“It took a long time to kind of plan, but we’ve been so happy that we went through this,” he says. “The moment we stepped in, it just felt right. It felt like home.”
